Abstract
A mechanistic structural design procedure for pavements containing cement- and lime-treated layers is outlined. The procedure includes provision for use of a range in traffic wheel loadings, fundamental material properties, and failure criteria, including fatigue. Layered elastic theory is utilized to calculate stresses and strains at critical positions in the pavement components, and these are compared with allowable values to minimize specific distress modes. Use of standard designs resulting from the more detailed analyses are discussed and explained. Reasonable agreement between predicted and actual response and behavior of several trial pavements are noted. Three design examples illustrating the procedure are included.
