Study of Mastic-Aggregate Interfacial Adhesion in Cement Emulsified Asphalt Mixture Based on the Discrete Element Method (DEM)

Abstract:

Cement emulsified asphalt mixture is a kind of composite materials, which is comprised of organic and inorganic materials, such as emulsified asphalt and cement, and has both advantages of cement concrete and asphalt concrete. Aiming at the problems of cement emulsified asphalt mixture that adhesion decline and road performance down in the using of process, the Discrete Element Method (DEM) was used to simulate two different kinds of aggregate used in the mixture. Through comparing the splitting strength, stress-strain curve, fracture development situation, and so on, suitable aggregate type, limestone aggregate, was obtained, which had higher adhesion property with cement emulsified asphalt binders.
