| Abstract | Lateritic soils, which are found in much of Thailand, are used as basecourse in road construction, resulting in a lower over-all cost. Stabilized with Portland cement and protected by a bituminous surface I treatment, pavements for lightly travelled roads are obtained. Such a basecourse is strong, stable, and has little susceptibility to change in moisture or temperature. It is more flexible than Portland cement concrete. Its modulus of elasticity is low as compared to the modulus of elasticity of Portland cement concrete. Although such pavements are i neither flexible nor rigid, the controlling factors in design may be either the slab strength of the lateritic soil-cement mixture or the supporting value of the subgrade soil. In both cases, the modulus of elasticity and Poisson's ratio play an important role in the dimensional design of the pavements. In addition, as the strength of a pavement is directly related to the elasticity constants, these constants must be determined to explain the behaviour of the lateritic soil-cement when loaded. For this purpose, investigations were made from mixtures involving one type of lateritic soil which was held constant and three different percentages of Portland cement. Laboratory tests were conducted on a lateritic soil obtained from a horizon located in Saraburi province. As the strength and modulus of elasticity of an artificially cemented soil mass, such as soil-cement or soil-lime-fly ash, is theoretically highly dependent on the intimacy of grain to grain contact, the controlling factor is the degree of compaction. With this in mind, specimens of lateritic soil mixed with |
