Title: Performance of lateritic soil cement road in Thailand
Abstract: As there was a deficiency of rock products for road construction in north eastern Thailand, soil cement was used to replace crushed rock for base course nearly two decades ago. There are about 1400 kilometers of soil cement road constructed in this region. However, soil cement road construction was terminated more than ten years ago because the reflected cracks made the highway engineer doubtful about its long term performance. In order to study the feasibility of employing soil cement for crushed rock, and to study the design and performance of the existing soil cement road in this region a long term research project was proposed. After analyzing all the pertinent data it could be concluded that soil cement roads, even though serving traffic for 12-16 years, exhibited a very good performance compared to crushed rock base roads. Soil cement pavement is more stable, and no plastic failure is common. Results of recent research on lateritic soil cement indicated that reflected cracks could be eliminated if the unconfined compressive strength of soil cement is kept in a proper range.
