PRACTICAL LESSONS ON ROAD CONSTRUCTION IN BLACK COTTON SOIL AREAS

The paper outlines the lessons learned in the construction of embankments and pavements over black cotton soil subgrades. The performance of the Indian Roads Congress test track project at peravali, a.p. especially constructed for the purpose provides the basic material for the paper. In the case of embankments built up of black cotton soil, it is reiterated that pulverisation of clods, compaction at field optimum moisture content, checking up on the density obtained, shoulder treatment and protection of side slopes need special attention. Introduction of a granular blanket course, maintenance of a minimum free-board and provision of good drainage conditions are highlighted as some of the prerequisites for the successful performance of a flexible pavement on black cotton soil subgades. Further, a comparison between the performance of different types of blanket courses and sub-bases has been attempted.(a) (TRRL)
