In the present study, two different data-driven models, artificial neural network (ANN) and multiple linear regression (MLR) models, have been developed to predict the 28 days compressive strength of concrete. Seven different parameters namely 3/4 mm sand, 3/8 mm sand, cement content, gravel, maximums size of aggregate, fineness modulus, and water-cement ratio were considered as input variables...

Concrete, the most consumed man-made material worldwide, has shaped environment and modern world. Even though concrete is a major contributor to carbon footprint, it indispensable for building sustainable world of tomorrow. Researchers have been exploring ways reduce footprint implement strategical waste management plans in which wastes are repurposed. Pollution challenge almost all countries, ...

Cracking is a major distress in asphalt pavement which can lead to premature pavement failures and can cost agencies millions of dollars in maintenance and rehabilitation costs. Even with modern advances in pavement engineering, attempts to quantify and model cracking in asphalt pavements have proved extremely challenging; this is due to the visco-elastic behavior of asphalt concrete and the co...

Reclaimed asphalt pavement is used as an aggregate in the cold recycling of asphalt paving mixtures. The more common method involves a process in which the asphalt pavement is recycled in-place (cold in-place recycling), CIPR. Where the Journal of Engineering Research (University of Tripoli) Issue (20) September 2014 67 reclaimed asphalt pavement is combined without heat with foamed bitumen and...

ii To my family, friends and professors who helped me throughout this experience iii ACKNOWLEDGEMENTS This research project was made possible with the help of many supporting people throughout the process. I wish to express my gratitude firstly to my supervising professor, Dr. Hosin " David " Lee for the support and advice needed to start and finish this project. I would also like to thank the ...

The classical asphalt mix manufacturing commonly requires the heating and the complete drying of aggregates. The induced energy cost has opened the way to develop alternatives processes with low energy/ carbon materials such as Warm Mix Asphalt (WMA). Their manufacturing requires specifics techniques to achieve similar performances than Hot Mix Asphalt (HMA). However, manufacturing temperature ...
