Abstract

Abstract

This paper studied the relationships of dynamic elastic modulus with compaction, and moisture content with PFWD. It was pointed that the obtained satisfactory correlations of dynamic elastic modulus with static elastic modulus, compaction with moisture content are over 0.85, the maximum value of dynamic elastic modulus is near by the optimum moisture content, which is agreetment with the real situation. The result shows it is feasible to measure and evaluate subgrade resilience modulus with PFWD.
