Experimental and Theoretical Investigation of Pavement Deflections

Abstract

The project represents a coordinated study involving a laboratory investigation, theoretical analysis and field measurements of stresses induced in flexible pavements by moving wheel loads. The laboratory tests indicated that the modulus of resilience is virtually independent of stress intensity and number of load repetitions provided the boulder clay samples are preconditioned. The theoretical (finite) element program was developed to the stage where either linear or nonlinear material properties in any combination can be handled in pavement structures of one to four layers. Results of trial problems indicate that the finite element program is working correctly and yields realistic answers to pavement deflections. Results are presented.
