This document discusses the advantages and disadvantages of using recycled aggregates in
construction. The main advantages are that it promotes sustainability by reducing waste and using
less natural resources. It can also reduce costs. However, recycled aggregates may have varying
quality and inconsistencies that make them less suitable for some applications. Proper processing is
needed to ensure quality and consistency.

Asphalt concrete is extensively used to build roads. Asphalt concrete mainly contains asphalt
which is used as a binder and some other aggregate of minerals. Asphalt layer is laid upon a base
of gravel layer to construct a stiff and dependable road. Asphalt can be categorized into different
categories depending on the laying temperature of the asphalt.
advantages of asphalt :-
Asphalt is used for highways having high volume of traffic. These roads are lower in cost and
produce lower noise making it more suitable for regular usage with safety. It also offers higher
traffic speed and is easy to repair as well
disadvantages of asphalt :-
However, Asphalt roads are less durable and become soft in hot weathers. Higher temperatures
can soft down the asphalt binder making the roads softer. Thus a heavy load on such soft surface
can deform the surface. However, very cold temperature can cause the contraction of asphalt
resulting in the formation of cracks. Good maintenance can increase the durability of the roads. It
also reduces the cost of repairing

real threat in both the short and long term. For one thing, asphalt has very high thermal mass
properties through which it can retain heat generated from the sun. Said heat is slowly released
from pavement over time, creating the heat island effect, which is responsible for increasing
temperatures in some cities by as much as ten per cent relative to surrounding rural areas.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Impermeable, surficial materials such as massive bedrock and asphalt paving prevent infiltration so
moisture runs off or evaporates. Water infiltrates more readily into moist, unsaturated regolith than
into dry regolith. Dense, vegetative cover enhances infiltration because soils are typically moist and
porous, thus runoff is retarded. In forested areas, trees slow down the rate at which precipitation is
delivered to the land surface, and considerable moisture is temporarily stored in humus and forest
litter. On gentle, tree covered slopes and flat lying terrain, slow runoff enhances infiltration. Runoff
is accelerated on steep slopes and in areas with sparse vegetation, and infiltration decreases
accordingly. The rate at which water is delivered to the land surface has a very important effect on
infiltration. Short–lived storms with intense rainfall result in lower infiltration and increased runoff
because the water "piles up" on the surface faster than it can infiltrate. During periods of light to
moderate rainfall, runoff is retarded and infiltration rises accordingly. Special environmental
conditions, such as snow melting above frozen ground, greatly intensify runoff and reduce
infiltration; conversely, snow melting above unfrozen ground can result in a high percentage of the
moisture infiltrating the soil. Thus regional and local climatic factors are also important. 9. How

If we say "pavers", and you think of bricks, you are in for a surprise. Pavers are a huge part of our
hardscapes, and there are enough different types to warrant a whole page.
NATURAL STONE PAVERS: These may be limestone, flagstone, or shale. For more exquisite
tastes, consider marble, travertine, or granite.
CULTURED STONE PAVERS: If you desire the look of expensive stone but would rather avoid the
price tag, or simply don't want to have the weight of the real stone to deal with, consider using
cultured pavers. These manufactured replicas are just as durable, lighter, and less expensive.
Choices then break into the following groupings. Some categories consist of natural and cultured
options, while others, such as the permeable varieties, ... Show more content on Helpwriting.net ...
While some of these are in overlapping categories, such as grass pavers or interlocking concrete,
that isn't necessarily true for all of them.
INTERLOCKING CONCRETE PAVERS: This style is another permeable paver, and they lock
together for a good, tight fit. These make beautiful patios, walkways, and driveways. Some are
standard shaped, but others are special shapes which interlock in beautiful patterns. The standout,
defining feature of these pavers is that they give a solid appearance. The materials, however, allow
water to seep through. This advantage is not found with all types of pavers, and sometimes this is
the reason to opt for this type of paver.
BRICK PAVERS: These kiln–fired blocks are one of the most common types of building materials,
and there are millions of homes around the country with bricks in the patio or walkway. They are
durable.
GRASS PAVERS: These pavers are an amazing technological feat. The purpose of these pavers is to
manage the rainwater, and allow it to move back into the ground while keeping the ground stable
and solid. They are beautiful as well, and can almost be an art form of their own. The geometric
shapes can be complex, or quite simple, but all are a beautiful way to enhance your grounds while
allowing a green space. These are wonderful for people who may have smaller yards. If you have

8. Advantages And Disadvantages Of Roller-Compacted Concrete
Roller–compacted concrete (RCC) is a stiff mixture of aggregates, cementitious materials, and water
with zero slump. RCC is consolidated or compacted in the fresh state by use of a roller with or
without vibration. RCC typically is placed with asphalt paving equipment in thicknesses of 4 to 8
inches for pavement application. RCC has gained the attention of the paving industry in recent years
and is becoming more popular day by day because of its low cost, rapid construction, and durable
performance. The energy required to compact RCC mixtures to their maximum densities is much
greater than for concrete of measurable slump. The largest difference between RCC mixtures and
conventional concrete mixtures is that RCC has a higher percentage of fine ... Show more content on

(ii) Low unit costs of RCC: The unit cost of low paste mass concrete is favorable; to reduce the heat
of hydration a significant portion of cement is usually replaced by locally available pozzolanic
materials or fly ash.
(iii) Incorporation of spillway into dam body: Due to the slope of the downstream face of 1:0.8
(gravity dams) to 1:0.4 (arch–gravity dams), the spillway can directly be incorporated into the dam
body which helps to accommodate large floods and which are in need of large spillways.
(iv) Use of shape of conventional dams: Because the stresses in gravity type dams are low, the
cross–sections of RCC dams are the same as those of conventional dams.
(v)Heat generation: RCC is more favorable while taking into consideration the heat dissipation
which always remains a vital issue for mass concreting structures.
Because of the above advantages, RCC dams are interesting alternatives to conventional dams in
most parts of the world. An example of RCC dam is shown in the Figure–1 built along Santa Cruz

scuffing, mixes are typically designed with polymer–modified binders. Fibers are often added to the
mix to reduce drain down. Many states have a specification for open–graded friction courses and
asphalt treated permeable bases that may be used in specifying mixes for porous asphalt
pavements." (U.S. Department of Transportation, 2015). An added advantage to using porous
asphalt is that it does not need proprietary ingredients. It also does not require the contractor to have
special paving equipment or skills other than those needed to place normal asphalt. With the proper
information, most asphalt plants can easily prepare the mix and general paving contractors can
install it. State specifications should be checked to see if they abide by the key properties shown in

Rating System in Nigeria Going Green In Nigeria OMOEFE AGHIMIEN 119051038 ABSTRACT
Green building rating systems are in a state of constant flux and often differ from region to region.
Regardless, fundamental principles persist from which the rating system is derived. These include
sustainable sites and structure design efficiency, water efficiency, energy efficiency, materials
efficiency, indoor environmental quality, operations and maintenance optimization, innovation and
design process, waste and toxic reduction etc. The essence of green building is an optimization of
one or more of these principles. The green building rating system, LEED® ... Show more content on

* Reduced air and water pollution (with direct health benefits) * Reduced water consumption *
Limited waste generation due to recycling and reuse * Reduced pollution loads * Increased user
productivity * Enhanced image and marketability. The concept of sustainable development can be
traced to the energy (especially fossil oil) crisis and the environment pollution concern in the 1970s.
The green building movement originated from the need and desire for more energy efficient and
environmentally friendly construction practices. There are a number of motives to building green,
including environmental, economic, and social benefits. However, modern sustainability initiatives
call for an integrated and synergistic design to both new construction and in the retrofitting of an
existing structure. Also known as sustainable design, this approach integrates the building life–cycle
with each green practice employed with a design–purpose to create a synergy amongst the practices
used. Green building brings together a vast array of practices and techniques to reduce and
ultimately eliminate the impacts of buildings on the environment and human health. It often
emphasizes taking advantage of renewable resources, e.g., using sunlight through passive solar,
active solar, and photovoltaic techniques and using plants and trees through green roofs, rain
gardens, and for reduction of rainwater run–off. Many

The recycled aggregates can undergo some processing procedures and adaptation to the desired
characteristics. Some of these processes are: homogenisation, crushing and screening and
autogenous cleaning. The homogenisation process Material aims to standardise and remove waste
materials such as wood, steel, plastics, among others. Initially, construction waste and demolition
are separated by the predominant color: gray or red. It is then performed quartering, where the
material is distributed in different layers along a plastic and from the middle section, they are
divided into several sections entitled cells. The material is then sent to a crusher where grinding
occurs (Kwan, Ramli, Kam and Sulieman, 2012).

Alternatively tyres can be recycled through civil engineering projects. These include projects such
as paving, erosion control and retaining walls. Tyres utilised in retaining walls are typically a
complete tyre that has been separated into halves prior to being filled with aggregate to increase the
structural integrity of the tyre before being placed in a number of possible configurations. The tyres,
once they are in their final configuration, can then be coated with a number of finishing products,
ranging from shotcrete to timber, to give a desired appearance. The construction method of these
walls can vary from a gravity supported system, where in the wall retains the earth through the
physical weight of the wall itself, to fully reinforced where further reinforcement is used to obtain
the desired strength and stability. It is common practice in construction of slabs for residential and
commercial buildings to use permanent internal formwork, which is the use of nonconcrete
materials to reduce the material costs when pouring the slab. Common practice is to use polystyrene
blocks to offset the amount of concrete used however it is possible to utilise tyres in the place of
polystyrene blocks furthermore it is possible to use site generated waste that would require to be

Salvador Minuchin, born and raised in Argentina, is known as the founder of structural family
therapy (Colapinto, 1982). Before creating what would be known as his most lasting contribution,
Minuchin spent years paving his way to his success. Traveling back and forth from Israel to the
United States, Minuchin finally settled down in the year 1954 where he began training in
psychoanalysis at the William Alanson White Institute in the United States (Nichols, 2014).
Following the White Institute, Minuchin began working at the Wiltwyck School, which consisted of
delinquent boys from unsystematic, multi–problem, underprivileged families (Colapinto, 1982). At
the time Minuchin began working there, therapists had found that certain clinical populations were
not responding to traditional psychotherapy (Lappin, 1988). In fact, the population of delinquent
children, like those that Minuchin was working with at Wiltwyck, resisted even more so than other
populations to this traditional psychotherapy (Lappin, 1988). This was due to the fact that the
traditional psychotherapeutic techniques used, were developed for middle–class patients who were
verbally articulate (Colapinto, 1982). It was then when Minuchin realized that a new model of
change was needed, particularly one that worked with unprivileged, delinquent boys (Lappin, 1988).

rent, and over 14 percent of households live in a rental apartments. The following chart list that 35%
of population rents, which does not seem much in comparison to 65% of house owners but they also
contribute a lot to this society. Multifamily housing has high potential for energy savings through
retrofits, but the lack of data on best practices and historical cost savings has weakened investment.
Data related to energy efficiency, utilities and construction is really difficult to obtain for a building,
as many multifamily owners and operators never benchmark the energy performance of their
building. This critical shortage of information about building energy performance has prevented
property markets from valuing energy efficiency and severely undermined both public and private
efforts to increase the energy efficiency of multifamily housing. This has really affected the
development of energy efficient and green policies in multi family building. Green building is about
improving our design and construction practices so that the multifamily homes we build today will
last longer, cost less to operate, and won't harm the health of workers and residents. It is also about

33. The Resource Of Tap Water
Water is a seemingly abundant source that is vital for basic life on Earth. This element not only acts
as a catalyst for human survival but is constitutional for certain entities of architecture such as
passive water cooling or permeable paving. Water is a renewable natural resource, but society's
uneconomical uses of this depleting resource may lead to a future of drought. Generally speaking,
one of the main types of water is tap water, which is water that undergoes through of series of
treatments that maintains a governmentally accepted water quality. In this paper, the resource of tap
water will be analysed through its process of its development, social expectations and inevitable
consequences that underlie in this resource.
Two hydrogen atoms and one oxygen atom are the basic components which fundamentally make up
a water molecule. However with the process of water treatment, chemicals such as chlorine (Cl) or
ozone (O3) are added to improve the safety and quality of the water (Water, 2014). Before the
system of water treatment was adopted, drinking water was often contaminated with bacteria which
led to water–borne illnesses such as cholera and typhoid. The concept of treating water was adopted
in India using the technique of sunlight to destroy bacteria, charcoal filtering and storage of drinking
water in copper compartments (Water, 2013). The city of Toronto receives their tap water from Lake

41. The Problem Of Wet Pavement Clusters
Introduction: According to the United States Department of Transportation, there were
approximately 2.6 million registered vehicles in 2014 and with that number increasing over the past
two years; the importance of studying our roadways and the materials that are used to produce
roadways is also on the rise [1]. There is a total of 2.7 million miles of paved roadway in the United
States. The primary material for paving those roads is asphalt [2]. Asphalt is a material that consists
of bituminous oil mixed with sand and gravel. Asphalt makes a good material for paving roads
because it is cheap and easily accessible, however, it does have its downsides. Wet pavement
clusters are sections of asphalt that become excessively slick after it rains. This phenomenon can
cause serious accidents that can be avoided by better understanding what causes wet pavement
clusters to occur and then researching different ways to stop them from developing. Research
Questions: There are three major questions that need to be answered to decrease the amount of wet
pavement clusters in the United States. 1. What types of components can be added to asphalt to
decrease the slickness of the pavement after it rains? 2. Are there components that can increase the
strength of permeable pavements? 3. Are there installation methods that can be paired with new mix
designs that increase permeability while still maintaining durability? Answering these three

they offered to provide the service to households for free through volunteer groups. Downspouts
need to be replaced approximately ten years installation and maintenance is minimal besides
ensuring the drainage area is functioning properly and not eroding as well as making sure the spouts
are clear of debris, holes, etc. The total cost of the program was $13 million, and 56,000 downspouts
were disconnected, which remove a total of 1.3 billion gallons of stormwater from their combined

According to the Environment Agency, 31% of land used for residential uses originated from
farmland. Two widely–used terms in this arena are brownfield and greenfield. Brownfield refers to
sites that have previously been occupied by a permanent structure, greenfield to virgin land. A
governmental target has been set for 60% of new housing to be sited on brownfield areas. As the risk
of flooding is expected to increase due to climate change, there can be a conflict between the desire
to build on flood–safe areas and to utilise brownfield sites, as many of the latter are situated in areas
known to be at risk from flooding. Another problem is that the greatest need for new housing is in
the South–East, whereas more available brownfield land is located in the North due to the decline of
heavy industry. Building on previous industrial sites has its own problems as there may be
contamination in the soil itself, something that has to be assessed at the planning stage as part of the

Question 1 a) Explain the affects that Urbanisation can have on the hydrology of a catchment.
Outline how SuDs can mitigate these impacts and explain the role and features of the following
systems: Permeable pavements Swale Detention Ponds Urbanisation affects the hydrology of a
catchment in various ways, it causes issues with the natural drainage of the environment by blocking
stream channels and removing trees which help break the momentum of rain. Urbanisation creates a
lot of surfaces that are impermeable which causes water build up, the water picks up pollutants and
chemicals and these are dispersed into streams and rivers. Roads and pavements collect rainwater
and channel it into waterways rather than letting it disperse into the ground, like it would if it had
not had any human intervention. SuDs have been introduced within construction projects now in
order mimic the natural drainage pattern of a specific area, these SuDs that are now being
introduced are aiding urban developments in allowing surface water to be managed well without
causing any impact on other sites. Permeable paving comes in a range of materials, it was designed
to allow water through a surface that would have usually be impermeable, they are generally used
on pathways, lawns and roads that only take light vehicle movements. They essentially reduce

permeability to allow rain and snowmelt to pass through it, thereby reducing the runoff from a site

1999). This base serves as a reservoir for stormwater runoff where water is allowed to infiltrate to
underlying permeable soils or is redirected through an overflow drain system. Filter fabric is placed
beneath the aggregate subgrade to prevent fine particles from moving into the soil bed. Essentially,
"porous pavement infiltrates and treats rainwater where it falls" (Ferguson, 2005, 10). The pore
space and aggregate base act as rainwater retention, reducing runoff during storm events. Further,
particles and pollutants are removed from the water flow through the filtration process, with the
underlying soils acting as a second filter treatment area and as a water recharge basin. Use &
Applicability Porous pavements are particularly functional as low–volume traffic surfaces and
parking areas and have been used for over thirty years. Early installations continue to function as
both parking lots and stormwater management systems. Cahill Associates (CA) designed one of the
first large–scale porous parking lots for an office park in a Philadelphia suburb. The design consists
of porous asphalt parking bays terraced down a hillside and connected by conventional traffic lanes.
The site is over 20 years old, has not needed repaving, and has staved off sinkholes in an area prone
