Pickering asphalt-water emulsions stabilized by polystyrene nanoparticles obtained from recycled material
Abstract: In recent years, emulsified asphalt has been found to offer numerous advantages over conventional asphalt. More recently still, emulsified asphalt stabilized with nanoparticles has emerged as an option for the construction field because this substance has many advantages over traditional emulsified asphalt, which is formulated with surfactants that tend to be less stable and more toxic. These new formulations are called Pickering emulsions. They can align with basic sustainability principles. …

Improving Highway Surface Course Properties of Asphalt Concrete for Heavy Traffic Loading using Mineral Fillers
Abstract: Failure signs seen on both rigid and flexible pavement as distresses is most often instigated by mix properties of the surface due to many factors. Traffic loading, Stripping or raveling is another possible cause of such effects. Stripping occurs when poor adhesion between asphalt cement and aggregate allows the aggregate at the surface to dislodge. As a result, mineral fillers in hot-mix asphalt concrete to obtain certain desirable properties has …

IMPACT OF HYDRATED LIME AND SBS ON HMA MOISTURE SUSCEPTIBILITY
Abstract: Abstract In recent years, many of the newly built asphalt and concrete roads in Baghdad and other Iraqi cities have broken down too soon. This has hurt the country's economy and public safety. One of the main reasons why these newly built roads break down is because of water damage. Leaking water weakens the bond between the aggregate and the asphalt, which makes it more likely that sidewalks will fall …
