A Laboratory Study on Acid Modified Bituminous Mixes in Comparison for Ruttin...civej
The rapid growth in trafficload intensity, tire pressure and traffic volume has put a hugedemand on
pavements to perform satisfactorily for the design period. A number of efforts are made in the past to
develop pavement materials that helped in attaining longer serviceability. Most of these efforts were
directed towards improving the design of bituminous mix through modified bituminous binders. In this
context an attempt is made to evaluate rutting characteristics of conventional bitumen modified with Poly
phosphoric Acid (PPA). Immersion Type Wheel Rutting Machine was used for evaluation of rutting
characteristics and is considered as one of the major critical criteria for design of pavement. Poly
phosphoric Acid (PPA) is added as modifier to virgin bitumen (VG – 30) at regular interval of 1% up to
6% to the weight of Bitumen. Bituminous Concrete of Grade-II is considered for Analysis. Slabs of
400X300X50mm are prepared for evaluation of rutting characteristics. Stability, density, voids and flow
parameters were determined using marshal test method for virgin and PPA modified mix. The result of
immersion wheel rutting explains that acid modified binders resist more rutting compared to virgin
binders. Acid modified mixes at 3% optimum performs better in rutting characteristics when tested in
laboratory for induced applied pressures, load and number of passes.

Design and Evaluation of Open Graded Hot Mix Asphalt Using Cement as A Grouti...IJMREMJournal
Road networks ought to be efficiently designed to be safe, speedy and loading sustaining as it has a significant
importance in country’s development. For that, pavement should be designed efficiently to exhibit better
strength, durability and economical at the same time. Generally, a pavement is classified as Flexible or Rigid.
Flexible pavement is opened early to traffic, has good riding quality and ease of maintenance but owing to heavy
loading conditions these pavements are more susceptible to wear and tear. On the contrary rigid pavement is
load sustaining, durable but having higher construction cost and poor riding quality. World is heading to semirigid
pavement which exhibits characteristics of both these pavements. It is the combination of cement concrete
and porous asphalt concrete which is achieved by leaving 25% to 30% air voids infused by cement grouts and is
known as Semi-rigid pavement.In this research, semi-rigid pavement was designed using ratio of grout of
optimum mix was 1:0.55 at water cement ratio by 2% of cement dosage with SP. Study concludes that, Semirigid
pavement’s Marshall stability of 7 days was almost 85% of rigid pavement and 28 days compressive
strength of semi-rigid pavement was almost 30.5% that of rigid pavement. Besides, it has been ensured that 7
days strength is comparable to 28 days strength of Semi-rigid pavement

This research work was carried out on concrete specimens made with different proportion of Ground Granulated Blast Furnace Slag (GGBFS) as a cement substitution in concrete. To accomplish the goal of the research work, overall 75 cubes and 60 cylinders were made. Out of 75 cubes and 60 cylinders, 15 cubes and 12 cylinders were cast for control concrete, and 60 cubes and 48 cylinders were cast by replacing 5,10,15 and 20% of cement with GGBFS. The cubes and cylinder specimens were 100x100x100 mm and 100x200 mm respectively, and mix design was done for 28 Mpa. All specimens were tested at 3. 7, 28 and 90 days of curing ages. The fresh properties such as workability and hardened properties such as compressive and tensile strength of all mixes were determined. Tests results showed that the workability of the concrete mixes made with GGBFS was higher than control mix. As the percentage of GGBFS increased the workability also increased. Hardened properties of concrete mixes made with GGBFS was lower than control concrete at early ages of curing. At the later age, hardened properties of GGBFS made concrete was more than control concrete. Furthermore, water absorption and density of GGBFS made concrete was lower than control concrete.
INFLUENCE OF VISCOSCITY MODIFYING ADMIXTURES ON FRESH AND HARDENED PROPERTIES...Ijripublishers Ijri
The use of self-compacting concrete (scc) in general building and civil engineering constructions is becoming popular
over the years ever since it was invented and guide-lines have been formulated by the efnarc (european federation of
national association representing concrete) in 2005. Although in india, we do not have any specific codal provisions for
scc similar to normal concrete, considerable research has been done in both development of scc and its applications with
various admixtures and fibers to enhance the properties of scc in hardened state. As scc is very sensitive to variations
in moisture content and gradation of aggregates, construction sites face difficulties in free flow of scc.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

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.
