INTRODUCTION
• Pavements and surface treatments are used to
provide a roadway wearing surface and to protect the
underlying material from moisture.
– Both concrete and asphalt mixes are used to construct
pavements.
– Because of their plastic nature, asphalt pavements are often
referred to as flexible pavements in contrast to concrete
pavements, which are identified as rigid pavements.
• Surface treatments, on the other hand, are produced
by applying liquid asphalt or some other bituminous
material to a roadway surface, with or without the
addition of aggregate.](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

The document contains numerous figures and tables to illustrate the different equipment types and their specifications.
Suspension bridges
This document provides an overview of suspension bridges, including their history, components, structural analysis, and types. Some key points:
- Suspension bridges have two towers that support main cables, from which vertical suspenders hang to support the road deck.
- Early bridges used ropes or chains, but the first design was in 1595. Modern bridges use steel cables anchored into solid tower foundations.
- The main forces are tension in the cables and compression in the towers. The cables form a parabolic shape and must be anchored at both ends.
- Underspanned designs run the main cables underneath but are less stable. Modern decks are aerodynamic trusses to withstand wind forces.

Rcc slab design guidelines
The document provides guidelines for the design of reinforced concrete slab structures, including:
1) The effective span of a slab is the lesser of the clear span plus depth or the center-to-center distance between supports.
2) The depth of the slab depends on bending moment and deflection criteria, and can be estimated using provided formulas accounting for steel percentage and load class.
3) Loads on the slab include dead load from thickness, floor finish, and live loads ranging from 3 to 5 kN/m^2 depending on building occupancy.
Michael Machnik ASBI 2011 Movable Scaffolding System presentation
The document discusses the benefits of using Movable Scaffolding Systems (MSS) for constructing multi-span bridges. MSS were first designed in the 1970s and have since been used successfully on over 100 bridge projects worldwide. MSS are lightweight, easy to assemble, and efficient. They can be adapted to different bridge designs and reused across projects. Self-launching MSS were developed to address challenges in moving supports over water or high piers without a crane. MSS provide faster construction with cycle times up to 50% shorter than traditional methods.

Effect of creep on composite steel concrete section
Creep and Shrinkage are inelastic and time-varying strains.
For Steel-Concrete Composite beam creep and shrinkage are highly associated with concrete.
Simple approach depending on modular ratio has been adopted to compute the elastic section properties instead of the theoretically complex calculations of creep.
Suspension bridges
A suspension bridge has three key components: cables that suspend the roadway from towers, towers that support the cables and transfer loads to anchorages, and anchorages that secure the cables using massive concrete blocks. The roadway hangs from the main cables by vertical suspender cables. Suspension bridges can span long distances between 2,000-7,000 feet due to the weight being transferred through cables to the anchorages. Construction involves erecting towers, spinning main cables between anchorages, attaching vertical suspender cables, and building out the roadway across the span. Famous examples include the Golden Gate Bridge and Akashi Kaikyo Bridge.

M6l36
This document discusses two approximate methods for analyzing building frames subjected to loads: the portal method and cantilever method. The portal method assumes inflection points at midpoints of beams and mid-heights of columns, and that interior columns carry twice the shear of exterior columns. The cantilever method assumes inflection points at beam midpoints and column mid-heights, and that column axial stresses are proportional to their distance from the storey's centroid. Examples demonstrate applying each method to determine member forces in frames.

Chimney one go
This document describes the slipform construction method for building reinforced concrete chimneys. The slipform method involves using hydraulic jacks to continuously lift steel formwork panels, allowing wet concrete to be poured without stopping to form continuous cylindrical shells. As the jacks lift the formwork by 1.5 to 3 meters per day, workers are able to place reinforcement, pour and finish the concrete, and cure the shell in a continuous, 24-hour process. Once the shell is complete, internal platforms and flues are installed along with other finishing work.
suspension bridge ppt
Suspension bridges have evolved over time through various innovations:
1) Early bridges used ropes and chains that were later replaced by stronger steel cables
2) Advances allowed building foundations underwater and constructing taller towers for longer spans
3) Later bridges had to withstand forces like wind and earthquakes, leading to designs that added stiffness and flexibility
4) Modern construction involves building tower foundations, spinning main cables between anchorages, attaching vertical cables to the deck, and lifting deck sections into place section-by-section.

Wind Analysis and Design of G+11 Storied Building using STAAD-Pro
This document presents a study analyzing wind loads on a G+11 storied reinforced concrete building using STAAD-Pro software. A 3D model of the building was created in STAAD-Pro based on specified dimensions and material properties. Wind loads were estimated according to Indian code IS 875 (Part 3)-1987, taking into account basic wind speed, zone factor, and height factor. Static analysis was performed considering dead load, live load, and wind load. Results found that deflection and forces increased with height and were highest under wind load in the x-direction. The study concluded wind loads are more critical for tall structures and designs should consider loads in both directions to determine critical forces.
[Awad s. hanna]_concrete_formwork_systems_(civil_a(book_zz.org)
1. Concrete formwork provides support and containment for fresh concrete until it can support itself. It molds the concrete to the desired shape and controls its position.
2. Formwork accounts for a large portion (40-60%) of the cost of a concrete structure. Reducing formwork costs and construction time can provide significant savings.
3. Faster forming cycles allow for quicker stripping of forms and reshoring, accelerating the overall construction schedule. Proper formwork design and construction also improves worker safety on the jobsite.

Introduction to Slurry Seal - Todd Vargason, Ergon Asphalt and Emulsions
A slurry seal is a mixture of asphalt emulsion, crushed aggregate, and other additives that is spread over the surface of a pavement. It fills cracks, adheres firmly to the surface, and provides a weatherproof layer that extends the life of the pavement by 5-7 years. Application is fast, taking only 15 minutes for a typical residential street. It restores texture, protects the pavement from oxidation, and preserves the underlying pavement from further deterioration.

Porous road construction _ Asphalt as a healing material
Self-healing technology is a new field within material technology. It represents a revolution in materials engineering and is changing the way that materials behave.
Incorporating self-healing technology into the road design process has the potential to transform road construction and maintenance processes by increasing the lifespan of roads and eliminating the need for road maintenance.
By decreasing the unnecessary premature ageing of asphalt pavements, self-healing asphalt can reduce the amount of natural resources used to maintain road networks, decrease the traffic disruption caused by road maintenance processes, decrease CO2 emissions during the road maintenance process and increase road safety. In addition to environmental savings, self-healing materials have the potential to deliver significant cost savings for road network maintenance across the EU..
There are three main self-healing technologies available for asphalt pavement design:
Nanoparticles,
Induction heating and
Rejuvenation.
This study reviews all three options and outlines the future development of self-healing asphalt technology

Structural Analysis of Stabilization and Consolidation Settlement of Selected...
The problem confronting roads in Nigeria is increasing immensely. It is ranging from folding or deflection of road surface and cracking due to improper investigation, soil stabilization and consolidation. Soil stabilization is of great importance because it is used to improve on site materials to create a solid and strong sub base and base coarses. Unsatisfactory soil and solids structures which do not have the desired quality as an engineering material need stabilization so as to improve its engineering material for better construction. This work is aimed at determining structural analysis of stabilization and consolidation settlement of soil structure interaction. This is done to ascertain the effect of soil stabilization of selected laterite using cement, lime and bitumen. Liquid limit test, compaction test, Plastic limit test and California Bearing Ratio CBR test were conducted using comparing Mechanical, Chemical, Cement and Bio Enzymatic stabilization method. It was observed that Cement stabilization is the best option as it could effectively implemented in this work. Ohaofia soil that is treated with 10 ordinary Portland cement can be recommended to be used as Base coarse for road construction. This is because its mixture satisfies both the strength and durability requirement that were set by different agencies for the Base coarse materials. While for Isikwuato soil was treated with 8 bitumen is recommended for Road Sub base surface as it gave the highest CBR value. It is observed that Lime is not a good stabilizer for road construction, but the CBR value achieved met up required standard for Road and Bridges. Based on the various results obtained, it is recommended that utilization of the locally available soil should be given due consideration for upcoming road construction within the study area and Cement stabilization is more suitable for road construction.

An attempted has been made to evaluate the strength
and performance characteristics of cold mix bitumen using
reclaimed asphalt. An experimental result obtained from
laboratory testing of the physical and mechanical parameters of
the recycled material, in which the material from the existing
pavement layers were analyses. The air void content, Marshall
stability and flow of the recycled mixtures were investigated. The
tests were performed on the road base mixtures incorporating
reclaimed asphalt pavement (RAP) with bituminous emulsion. It
was observed that the reclaimed asphalt was having impact
strength of 10%, crushing strength of 8.2%. It is significant to
note that the reclaimed aggregate which was subjected to loading
condition already was still showing very good strength properties.
The maximum stability obtained from optimum binder content
was 384 kg which is a very good value for a cold mix made up of
reclaimed asphalt aggregate. The flow value obtained was also
5.06 mm as observed. The aim of the tests was to evaluate the
properties of the mixes in terms of the recycled aggregates.
Satisfactory results were obtained.

Eccentrically Loaded Small Scale Ring Footing on Resting on Cohesionless Soil
A number of works have been carried out for the evaluation of a ultimate bearing capacity of shallow
foundation, supported by geogrid reinforced sand and subjected to centric load. Few experimental studies have
been made on the calculation of bearing capacity of shallow foundation on geogrid-reinforced sand under
eccentric loading. However these studies are for strip footings. This paper presents the behavior of ring footing
under eccentric loading on sand. The model tests have been conducted using ring footing with ring radii ratio
(Di/Do) = 0.4, 0.6, 0.8 for varring eccentricity ratio. Parametric studies have been made to find the impact of
eccentricity ratio, ring radii ratio and geogrid reinforcement on bearing capacity of the foundation.
