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.

This paper analyzes the principle of the LP-LFC process,presents the physical and mathematical models of mould filling of the new process. The patterns including window-plate, ladders cluster, electromotor frame and exhausting manifolds are poured using LP-LFC process with AZ91D alloy, and the mould filling course is tracked with electrode touch point method. Based on above tests and experiments,the casting defects including short runs, cold laps, trapped gas,metal penetration, and so on, were investigated. The appearance characteristics,birth causes and influence factors of above defects are discussed in the article,diagrammatize modes of the defects forming is also given, and the measures of reducing or avoiding defects are put forward.
