Abstract: | Investigation of performance of Full Depth Reclaimed Surface-dressed Pavement (FDRSP), treated with cement and Calcium Carbide Residue (CCR) as road base was undertaken. Wearing and base courses of a surface-dressed road was scarified and mixed to form the FDRSP, which was found to consist of 28.7 % Reclaimed Surface-dressed Pavement (RSP) and 71.3% soil from the natural base course. Laboratory tests were carried out to determine the most optimal of FDRSP/cement/CCR that will give a California Bearing Ratio (CBR) value of 150%, required for heavy traffic roads. The results showed that the original base course material of the road classified under A-2-5, but when mixed with Reclaimed Surface-dressed Pavement (RSP), the resulting material (FDRSP) classified under A-2-4 according to AASHTO soil classification system. 2% cement and 4% CCR, added to the FDRSP, satisfied the 150% CBR required for heavy traffic roads. From laboratory and field test results of the FDRSP/cement/CCR composites, soaking did not have adverse effect on the strength |
