This report discussed the use of cement stabilization for granular bases and sub-bases. The static strength AS Measured in unconfined compression, or in tension, is influenced by compaction, air voids and cement and moisture content. Under repeated loading, lower strengths are obtained. Generally, granular bases achieve very high strengths when cement stabilized and while they are intact. The stiffness is of interest in design using elastic approaches, this may be related to static strength. Again, very high values are common, but these are for the material in the uncracked state. Breakdown of the material due to shrinkage or traffic stresses reduces the modulus to near the unstabilized value. Design approaches using conventional methods or substitution ratios are discussed. These are often unsatisfactory and there is need for a design approach which will account for the particular properties of these materials as they exist in the pavement. /TRRL/
