  • For compaction works, it is necessary to spot-check the density of compacted backfill, usually by means of the sand cone test. However, this method is time-consuming. A light-weight deflectometer (LWD) developed for evaluation of surface stiffness may be employed to estimate the degree of compaction. In this study, the following tests were performed on a lateritic soil: (i) modified Proctor compaction test to determine the optimum water content (wopt) and the corresponding maximum dry density… CONTINUE READING
