Abstract

A survey was carried along the Puchong-Kajang highway mainly in Puchong, Selangor. 12 stations were visited and soils samples were collected from six stations for laboratory analysis. The slopes for soil sampling are soil slope type with the grade of weathering from IV to VI. The soil samples were collected from stable and failed slopes. The physicochemical properties of soil including of water content and water in the saturated state, organic content, particle size distribution, bulk and true densities, porosity, clay dispersion, pH and iron oxide content. The water content showed higher percentage infailed slope than stable slope samples. All samples indicated that the field water content was below the saturated state. The organic contents were very low (<2%) and the soil can be classified as potentially unstable. A positive correlation was seen between water content and organic matter mainly for unstable slope. The porosity of soils showed a positive correlation with clay and organic matter Most of the soils were classified as sandy clay. The coefficient values of clay fraction indicated that the soil structure confined in stable to very stable classes compared to one station classified as unstable. In general, the soils were acidic (pH4.87 - pH4.34) with the presence of iron oxide less of than 6%.
