Comparative Research on Pavement Performance of Cement Stabilized Macadam Base in Different Molding Methods

Abstract:

The indoor molding methods don't match the actual degree of compaction, which will cause the compaction over one hundred degrees and the more reflective cracks of the cement stabilized macadam base. In order to prevent this kind of phenomenon, a series tests on two kinds different molding methods were conducted. It contained maximum dry density, UCS,drying shrinkage performance and impact of aggregates performance .The results show that the dry density and UCS(unconfined compressive strength) of vibration molding are greater than isostatic pressing method's, the drying shrinkage performance of vibration molding is better than static pressure molding's. The vibration molding has less affected for the aggregate performance. It is more similar to the actual field.
