Abstract: Pneumatic transport of solids in a riser has a unique nonuniform flow structure, characterized by the core solids acceleration and the wall solids deceleration along the riser, which causes the downflow of solids and hence ...

Abstract: Previous research has proved that paraffin has a negative effect on the mechanical properties of asphalt binder; however, until now there are very few studies on the fundamental mechanisms on a microscale. To study the ...

Abstract: Workers involved in asphalt pavement construction are exposed to asphalt fumes. The adverse health effects of asphalt fumes have long been recognized; however, there is still a lack of consistent and systematic approaches ...

Abstract: The long-term durability of both coarse and fine aggregate significantly affects the mechanical performance of asphalt pavements. Extensive investigations of aggregate durability have been conducted on coarse aggregate in ...

Abstract: Asphalt pavements are commonly used for highways and airport runways. In pavement design and analysis, environmental factors such as temperature need to be taken into account to accurately predict the service life of asphalt ...
