The Meso Structure and Strain Distribution Analysis of Cement Emulsified Asphalt Concrete
並列摘要
In this article, the mix design of Cement Emulsified Asphalt Concrete (CEAC) is introduced. A 2-dimensional image of CEAC obtained in meso scale could be distinguished into 3-phase materials that include cement emulsified asphalt mastics, aggregates, and air voids. Then, an FEM model is used to simulate the steady mechanical behaviors of CEAC in which cement emulsified asphalt mastics are defined as dispersions of aggregate fillers within a medium of binder. The virtual indirect tensile test is simulated to study the strain distribution of CEAC and the results show the cement-asphalt binder can be considered as the weak failure phase material. In addition, the influence of mechanical properties of aggregate and cement-asphalt binder are discussed and the results show that the strain distribution of CEAC is sensitive to the elastic modulus of cement-asphalt binder.
