STABILIZATION OF SRINAGAR SOIL WITH.. SPECIAL REFERENCE TO FROST ACTION

Abstract

one of the most important factors affecting the pavement performance is climatic condition. Many studies have shown that frost-susceptible soils ex-perience a severe loss in strength during frost melting periods.. Recently stabilization of soils are being tried keeping in view both, the strength and durability. The review of. the published work on soil stabilization with special reference to freezing and thawing constitutes the zs at Part of the thesis. The pavements in: Kashmir valley and Northern Border Roads are found to ,get damaged needing frequent and costly maintenance work, It.is suspected that .the main cause of failure of pavements in this region is due to the frost action prevalent during the winter season. The LEnd Part consists of the laboratory investigations carried out on a typical frost susceptible soil sample from Srinagar (Kashmir). A number of stabilizers were tried and the stability, volume change, and water absor. ption values of stabilized samples were noted under different testing conditions such as soaking, freeze. thaw and wet-dry conditions. It was observed that soil stabilized with 6 percent cement and 4 percent lime may be the most economic proposition which may be reco-mmended for base courses of light traffic roads.
