RESPONSE OF FLEXIBLE PAVEMENTS TO MULTIPLE LOADS

Instrumentation data obtained in the multiple-wheel heavy gear load tests conducted at the U.S. Army Engineer Waterways Experiment Station are analyzed, and the results of this analysis are presented. The nonlinear pavement response to loads is illustrated. The patterns of measured stresses, deflections, and deflection basins under different wheel assemblies and loads are delineated, and pavement performance (in terms of coverages to failure) under traffic loads is examined. It is shown that single- wheel loads cause deflections in the upper layers, while multiple-wheel load deflections extend to the deep subgrade soil. The validity of the superposition principle is manifested, and the application of this principle to pavement analysis is emphasized. /ASCE/
