This report summarizes the findings of an evaluation and interpretation of the results from previous studies concerning the tensile and shrinkage characteristics of cement-treated materials. Findings of studies performed at the Center for Highway Research to determine the tensile characteristics of cement-treated materials are summarized and detailed discussion of the findings of a number of studies to determine the shrinkage properties of cement-treated materials is presented. The effects on tensile strength produced by eight factors previously shown to be important are analyzed in detail and the effects are evaluated in terms of their significance and relationship to shrinkage cracking of cement-treated materials. Based on these evaluations, a modification is proposed for the Texas Highway Department mix design procedure, which should improve tensile strength and minimize shrinkage cracking. In addition, recommendations regarding the construction of cement-treated bases and subbases for improved tensile strength and reduced shrinkage cracking are made.
