The Preventive Effect against Frost-Heaving of a Certain Synthetic Soil･Conditioner

摘要

We examined the effect of a certain soil-conditioner as an anti-frost-heaving agent. In order to explain the mechanism of anti-frost-heaving effect we carried out experiments such as frost-heave、size distribution of soil、capillary height and permeability of water. According to our views　based　on　observations、the　preventive　effect　against frost-heaving depends on the coagulation of clay particles into larger particles and on the increase of resistance to flow of water through soil. 0f the two preventive effects、the latter has more predominating influence than the forrner
