Research on the Capability of Basal Layer Stabilized Gravel by Cement and Fly-Ash

Abstract:

Aiming at the basal layer demand on pavement performance in Tu – Wu Highway of Baicheng diversion road, based on the theory of gradution in mixture, experimental studies have been done in grade of gravel and road performance of stabilized gravel by cement and fly-ash. The right amount of cement and fly-ash in mixture can improve spatial structural components of mixture and its mechanical properties. Base on these measured datas, the mixture of cement and fly-ash mixed in the gravel is reasonable and feasible，and the results show its mechanical properties rely on mix proportion of the basal layer.
