Study of Soil Shear Strength using Dolomite Lime at Agriculture Road in Sungai Balang, Muar

Abstract In civil engineering, soft soil is the most common soil that has a problem occurring. The objectives of this study are to determine the basic and engineering properties of the soil, soil shear strength before and after lime stabilization for Sg. Balang, Muar area and effect of curing time for lime stabilisation. Samples were collected in Sg. Balang, Muar, where an agricultural road was damaged. The purpose of this study was to improve the shear strength of the soil by using dolomite lime. Core cutter method was chosen to collect undisturbed sample from agriculture road. The lime samples containing 3%, 6%, and 9% were utilized to stabilize the soil. The laboratory tests involve in this study are dry and wet sieve, cone penetration test, plastic limit test and unconfined compression test. The result shows that the soil can be classified as silty soil based on USCS classification. The specific gravity of the soil was 2.69. The results also indicate that the initial shear strength was 69.52 kN/m 2 , and that it increased to 81.78 kN/m 2 , 128.98 kN/m 2 , and 166.79 kN/m 2 with the addition of 3%, 6%, and 9% of lime, respectively. The shear strength of soil increased with the percentage of lime used, with higher shear strength after 9% lime addition. The shear strength of soil also increased with day of curing.
