Abstract
Raveling, mainly caused by interfacial failure between binder and aggregate or cohesive failure of asphalt mortar, is one of the major causes of premature failure in asphalt pavements, and it also accelerates the severity of other distresses. The experiential adhesive experiment named Vialit Test under low temperature was chosen to investigate the adhesion behavior between binder and aggregate in this paper. The influence of aggregate size, aggregate types, binder types and impact energy were discussed. Quantity of ravelling aggregates and weight loss of aggregate and binders were used to evaluate the adhesive performance. Test results demonstrate that aggregate types have limited effects on the adhesion at low temperature, while aggregate size, binder types and impact energy have significant effects on adhesive performance between binder and aggregate. Binders with fine fillers exhibit better adhesion to aggregate when compares with pure asphalt.
