Abstract: Asphalt binder is very sensitive to temperature and exhibits bonding or lubrication effects at different temperatures. The bonding/lubrication properties of asphalt affect the mixing, compaction, and service performance ...

Abstract: Aggregate segregation is an important factor affecting the early distress and durability of asphalt pavement. To analyze the segregation tendency of aggregates on the mesoscopic scale, first, the segregation tendency of ...

Abstract: Aggregate particles migrate and rearrange their spatial positions during the compaction process. To analyze the migration law, an accurate method to track migration of particles is proposed using discrete-element simulation ...

Abstract: To effectively evaluate the contact characteristics of a particle system, an aggregate contact-slip tester was developed in this investigation on the microscopic level. Contact indexes, including the maximum slip force, ...
