CRITICAL TENSILE STRAIN IN ASPHALT PAVEMENTS

CHARTS BASED ON TWO-LAYER ELASTIC THEORY ARE PRESENTED FOR DETERMINING THE CRITICAL TENSILE STRAIN AT THE BOTTOM OF THE ASPHALT-BOUND LAYER UNDER SINGLE, DUAL, AND DUAL-TANDEM WHEELS. THEY CAN BE APPLIED DIRECTLY TO FULL-DEPTH ASPHALT PAVEMENTS WHERE ONLY TWO LAYERS ARE INVOLVED. FOR A CONVENTIONAL THREE-LAYER SYSTEM, A METHOD IS DEVELOPED TO CONVERT IT INTO AN EQUIVALENT TWO-LAYER SYSTEM, SO THAT THE CHARTS CAN STILL APPLY. A COMPARISON OF THE CRITICAL TENSILE STRAINS OBTAINED FROM THE CHARTS WITH THOSE DETERMINED DIRECTLY FROM A COMPUTER PROGRAM CLEARLY INDICATES THAT THEY ARE ACCURATE ENOUGH FOR ENGINEERING APPLICATION. /ASCE/
