Abstract

Northeast China is located in the seasonally frozen area. Under the influence of low temperature, the roads are prone to serious problems. Modification of subgrade soil with industrial waste can effectively prevent road problems. In this study, fly ash and rubber crumbs were selected to be mixed with silty clay as roadway subgrade to prepare modified soil specimens with different dry densities. Matric suctions of the modified soil specimens were measured and compared to those of the unmodified soil specimens. Soil water characteristic curves for both modified and unmodified soil specimens were investigated and stability under low temperature was studied. The test results show that the matric suction changes with the density, but the change of the modified soil is smaller than that of the unmodified soil. The stability of the modified soil is better especially at low temperatures.
