This paper examines the mechanism of stabilization of expansive soil with cane molasses. The main objective of the study was to establish whether or not sugar cane molasses can be used as a stabilizing agent for expansive clay soil used for engineering purposes. Other objectives were to carry out analysis of cane molasses; to carry out strength assessment of neat expansive soil and expansive soil mixed with cane molasses as reflected by California bearing ratio (CBR). Cane molasses was selected for this purpose because it contained some elements/compounds which are known to react with clay minerals and change characteristics of the soil. It was established that 8% cane molasses by weight of dry soil was the maximum for effective stabilization of expansive clay soil. On comparison lime stabilized soil specimens gave higher CBR values than cane molasses. The conclusion was that the increase in CBR values for expansive soil mixed with cane molasses above those of neat expansive soil was an indication that cane molasses caused the increase in soil strength and therefore it stabilized expansive clay soil. It was also observed that cane molasses mixed with expansive clay soil could reduce swelling tendencies of the soil.
