Laboratory Characteristics on Frost Heave under Various Moisture Contents and Compaction Efforts in Pavement Subgrade Soils

실내시험에 의한 흙의 함수비 변동과 다짐도에 따른 동상특성

This study presents the laboratory properties on the frost heave under various moisture contents and compaction efforts in pavement subgrade soil. Many researches were conducted on the frost heave. However, the researches with the domestic soils have not been so active until now. In particular, the evaluation of the frost heave in pavement subgrade soils was not established by many researchers. The problems relating with the frost heave have been serious causes in the distresses of pavements. The study was performed using an appropriate field simulation. The research results revealed that the drainage conditions in earth work should be treated cautiously.
