Geotechnical properties of lateritic soil stabilized with sugarcane straw ash

Abstract

An increase in population with the demand of a wider road and also maintenance of transportation infrastructure has been alarming over the past few decades. Owing to this fact investigation will be carried out on laterite soil to improve the geotechnical properties of the soil to be able to stabilize the soil to withstand the load coming on it. In this investigation agricultural waste (sugarcane straw ash) will be used at varying percentage of 0, 4, 8, 10 and 12 to stabilized the laterite soil and improve the properties of the soil. The result indicates that with the increase of SCSA in the soil sample at 4% proportion ratio the soil strength is increased and at 12% it reduced drastically. The result of the tests shows that the strength of the soil is good when 4% SCSA are added. The optimum substitute increased the load bearing capacity of the soil thereby making an improvement to the lateritic soil.
