RESEARCH ON SUBGRADE FILLING EARTHWORK IN EXPANSIVE AREAS WHERE SECOND CLASS HIGHWAY PASSES

In this article, we choose a representative soil sample in expansive area where Chongzuo to Shangsi secondary highway passes, then mix it with cement, plain sand and sandy soil in some proportion, and get the mixed soil samples, then do the tests of physics, expansion and mechanics of these mixed soil samples. We compare their effect to improve expansive soils performance, and choose the kind of mixed soil as treatment project of subgrade expansive soil on Chong-Shang highway, which meets the demand of specifications on engineering and whose benefit is well on economic.
