THICKNESS DESIGN FOR EFFECTIVE CRUSHED STONE USE

The structural thickness design of a pavement section requires the following important factors to be carefully considered: (1) Equivalent wheel loadings; (2) Environmental factors such as temperature and water effects; (3) Quality and variability of available materials as related to their strength, durability and overall performance; (4) Proper subgrade testing and, if required, stabilization; (5) Actual selection of the required thickness of each layer; (6) An economic analysis including life cycle costs; and (7) Adequate field inspection and quality control. In this paper each aspect of the design process is considered. The most emphasis, however, is given to those aspects which directly affect the use and performance of flexible crushed stone base pavements. The economics of stone base is considered, and base course equivalencies are discussed.
