Résumé
The research in this thesis has been aimed at assessing the potential of desert caly plus lime, and cement kiln dust (CKD) for the stabilisation of desert sand in road pavements in the desert areas of Southeast Iran. Materials from Iranian desert ; a desert sand and a desert clay were used in the testing. X-ray diffraction techniques were employed to study the mineral constituents of the desert materials. Results obtained with sand-CKD, sand-CKD-clay, and sand-CKD-chemical additives produced better results and could be used as base or sub base depending on the mix proportions. These mixes may offer an economic option for road base and sub base materials and would certainly be cheaper than sand-cement mixes. This is provided by the use of only a small percentage of a reactive clay or trace amounts of a suitable chemical additive with sand-CKD mixture but, an adequate duration of moist curing time in the relatively high temperature is essential
