Abstract:

Rutting potential in asphalt concrete pavements (ACP) over both flexible (granular) and rigid (PCC) pavements is investigated. A detailed analysis of the influence of ACP mixture stiffness, stiffness ratios between the ACP surface and the supporting base, ACP layer thicknesses, surface shear, realistic tire contact stresses, and degree of interlayer bonding is presented. The result of the analysis is presented in terms of octahedral shear stress contours. Over 250 plots of octahedral shear stress contours for a wide variety of structural conditions are presented in Appendix C. The triaxial shear strength test and the octahedral shear strength calculated from the parameters of phi' and C' derived from the triaxial test are used, in concert with the maximum octahedral shear stress within a selected pavement structure and for selected conditions of interlayer bonding and surface shear, to develop a ratio of induced octahedral shear stress to octahedral shear strength.
