PROPOSAL FOR IMPROVED TENSILE STRENGTH OF CEMENT-TREATED MATERIALS

Tensile stresses created in cement-treated bases and subbases by shrinkage and wheel loads have been shown theoretically and from field observations to be very important to the design of pavement systems. However, there is little information that relates the mix design of cement-treated materials to the tensile characteristics of the individual pavement layers. This paper discusses the various mixture and construction factors involved in the design of cement-treated bases and subbases and relates these factors to the tensile and shrinkage characteristics of cement-treated materials. A rationale is developed for including tensile strength considerations in the design method utilized by the Texas Highway Department for cement-treated mixtures not only to improve tensile strength but to minimize shrinkage cracking. Finally, recommendations for the mix design and construction of cement-treated bases and subbases are presented.
