A Novel Approach for the Characterization of the Rutting Performance of Pavement Foundations

The dynamic nature of the confinement is often overlooked in the stress path testing of geomaterials in the laboratory. The disregard for the realistic nature of the moving wheel loads can potentially degrade the reliability of the permanent deformation parameters used in the rutting models.This effort will provide a Variable Dynamic Confining Pressure (VDCP) stress path protocol for permanent deformation characterization of geomaterials in the laboratory. The refined protocol will potentially eliminate the discrepancies observed between the laboratory-predicted permanent deformation and the rut depth measurements in the field. The outcome of the proposed research can potentially mitigate the unforeseen maintenance and repair costs associated with underestimation of the parameters of the rutting models for the design of pavement structures.
