摘要：	Discussed are the structural behavior and subsequent modeling of a typical rehabilitation pavement design of a pavement with stabilized layers (semirigid) in South Africa. The rehabilitation consists of a 150-mm, high-quality crushed stone on a pre-cracked-and-seated semirigid pavement. Its structural behavior was determined through full-scale accelerated testing with a heavy vehicle simulator and associated technology. The modeling was done with a nonlinear, multilayer finite element method. Typical results are given, together with detailed modeling of the pavement response. A manual method for backcalculation of nonlinear granular material properties based on multidepth deflection measurements was used successfully to fit the full deflection basins at different depths within the pavement structure.
