Study on the Method of Fixing Voids in Coarse Aggregate in SMA Mixture

Abstract:

The current volume design method of SMA is the comparison of volume characteristic parameters (VCA in the mixes,VCA in the dry rodded condition) between aggregates and the mixture,but ignores the systematic error between them.It is the different molding method and different tamping container that cause systematic error.The study compares Marshell compaction method and the Gyration compaction,tamping density tesy of Gyration tube and Marshell tube,and analysis the results.Choosing the Gyration compaction and gytatory tube to measure VCA is more reasonable.
