Abstract

The potential of cement kiln dust (CKD) and lime (quicklime) for stabilizing low-volume unpaved roads on sites dominated by cohesive soils was investigated. CKD, lime plus CKD, lime, and portland cement were tested at different mixtures and soil moisture contents in a clayey silt to determine the resulting unconfined compressive strength after three curing periods. In a field study, road sections were stabilized with CKD and with lime plus CKD, and then a gravel running surface was added. Soil penetration resistance increased after the treatment. Field results confirmed the laboratory results and helped identify the most effective treatment. Stabilization proved cost-effective for new roads in areas where gravel is difficult to obtain. This paper is also available on CD-ROM (see C 30152 CD-ROM).
