Feasibility Study of Cement Modified Mastic Emulsified Asphalt Concrete

Abstract

Abstract Cement Asphalt Concrete (CAC) is a newly developed cold-mixed pavement material at room temperature. In this paper, a kind of cement fast-cracked emulsified asphalt mastic and a gradation of stone mastic asphalt was used to obtain a high-performance pavement material. This material improves the gradation by calculating volume parameters and observing the state of the concrete, and then we determine the optimal cement asphalt mastic content through specific gravity, Marshall stability value and aggregate wrapping state. Finally, the Marshall stability value, flow value, indirect tensile strength and Cantabro loss were used to evaluate the performance of Stone Mastic Cement Asphalt (SMCA), Continuous-graded Cement Asphalt (CCA) and SMA. This paper shows that SMCA’s technical performance is relatively similar to CCA, and the Cantabro loss is much lower than CCA. In comparison with SMA, except for flow value, other performances are higher than SMA.
