The objective of this study is to review existing literature in the area of nano-modification of asphalt and proceed to apply nano-materials to asphalt to improve the performance. This study integrates literature review, preparation, and characterization of nano-modified asphalt materials. In the experimental testing montmorillonite, nanoclay at 2% and 4% by weight of asphalt was blended in asp...

Asphalt crumb rubber is a type of pavement material formed by mixing asphalt cement with that derived from recycled tires. This eco-friendly approach aids in waste reduction and promotes environmental preservation incorporating materials into construction. The study aimed to examine the behavior mixtures modified rubber, made blending tire-derived cement. Adding improved performance mixtures, 8...

The performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. Therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. One common method of improving the performance of asphaltic mixtures is using different types of ...

Work in the asphalt industry has been associated with nonmalignant respiratory morbidity and mortality, but the evidence is not consistent. A historical cohort of asphalt workers included 58,862 men (911,209 person-years) first employed between 1913 and 1999 in companies applying and mixing asphalt in Denmark, Finland, France, Germany, Israel, the Netherlands, and Norway. The relations between ...

The analysis of pavements and their ingredients has always been important due to a good understanding of their behavior under different conditions; that leads to more accurate relations. Due to the extent of asphalt mixture application in the world, the assessment of different behaviors of this mix is very important from various aspects of performance and safety. Given that the asphalt mixtures...

This paper discusses the laboratory design of continuously graded asphaltic concrete mixtures containing styrene butadiene styrene (SBS). The purpose of this study is to evaluate mechanical properties of control and SBS modified asphalt mixtures. Furthermore rheological properties of conventional and modified asphalt in different SBS content were studied. AC-10 was used as binder in the study. ...

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 ...
