MOUND SOIL AS A PAVEMENT MATERIAL

Abstract

The result of a study on some characteristics of laterite- cement mix containing termite mound soil (50% by weight of laterite) as replacement of laterite are presented in this paper. The study showed that laterite-mound soil mix stabilized with 6% cement could serve as a base course for roads for agricultural trafficking in rural areas where mound soils are abundant. At 6% cement stabilization the unconfined compressive strength (UCS) of 1.57 N/mm2 and a California bearing ratio (CBR) of 330% were obtained. The durability of the mix at this cement content was also found to be satisfactory with 87.7% resistance to loss in strength, and 1% weight loss and 1.15% volume change after 12 wet- dry cycle test.
