Three types of subgrade filling material are selected to analyze the change rule of subgrade resilience modulus under different compaction. Meanwhile PFWD（portable falling wei-ght deflectometer） is combined to integrate this parameter with compaction of construction control index,which brings about the conversion relation between three subgrade filling material and compaction. It can provide reference for pavement design and construction.
