Evaluation method of continuous compaction quality of highway water stable base

Abstract

This article summarizes several commonly used real-time monitoring indicators of compaction quality, proposes the methods for evaluating compaction quality of water stable bases. Two methods, the Kriging interpolation method and the geostatistical analysis method, are proposed for evaluating the spatial uniformity of compaction mass. The results show that: the Kriging interpolation method has strong extrapolation ability, and can consider the spatial correlation of data; the geostatistical analysis method can not only describe the structural variation of continuous compaction detection parameters, but also describe its random variation. It would provide reference suggestions for the compaction quality evaluation of water stable base.
