Abstract


Cement stabilized macadam asphalt pavement cracks easily , especially in heavy traffic conditions, road construction easier premature destruction . In this paper, the use of local raw materials , based on the proposed use of fly ash and adjust gradation two ideas to improve the cement stabilized macadam road performance . Meanwhile, with fly ash for cement stabilized gravel mix design , and through the mechanical properties, shrinkage , frost resistance and fatigue resistance and other road performance verification, the optimum mixture of fly ash dose and the most excellent mix . Then through the cement stabilized aggregate gradation on the performance impact studies, that the best gradation type. This paper proposes porosity index , through the analysis of cement stabilized Macadam road performance and the relationship between porosity , voids mixture obtained optimal range .
