Abstract

The quality and life of pavements are prominently affected by the sub-grade Strength. The key objective of this paper is to enhance the properties of black cotton soil using cutback asphalt MC-30. A Laboratory investigation is carried out to study the effect of cutback Asphalt on engineering and index properties of the Black Cotton Soil. The soil used in the study is brought from Thullur mandal, Andhra Pradesh, a major extent of this region is covered by black cotton soil.A series of laboratory tests are conducted, namely, USCS soil classification, specific gravity,optimum moisture content, maximum dry density, liquid limit, plastic limit, swell pressure, free swell index, California bearing ratio are conducted on soil samples with varied bitumen content ranging from 0% - 13% leaving intervals at 1, 5, 9, and 13 %, and tested thereafter. The results stand out the increase in liquid limit and plastic limit, and the fall in the swell pressure, free swell index on addition of optimum cutback asphalt. However, in case of stability case there is increase in California bearing ratio in soaked and unsoaked condition with increase in stabilizer (cutback bitumen).
