CRITERIA FOR ASPHALT-RUBBER CONCRETE IN CIVIL AIRPORT PAVEMENTS. VOLUME II--EVALUATION OF ASPHALT-RUBBER CONCRETE. FINAL REPORT

Asphalt-rubber concrete and an asphalt concrete control were tested in the laboratory and materials characterizations were generated, including Marshall Stability, resilient modulus, fatigue and fracture properties, creep compliance, and permanent deformation properties. The characterization parameters and an airport runway model for a municipal airport were input into the modified ILLIPAVE computer program for analysis of rutting and cracking damage and the relative lives of the materials in each of four climatic zones. An economic evaluation was then performed comparing the costs and service lives of each material in each zone. A cracking index of 0.2 was chosen as a comparative level. The asphalt-rubber concrete passed the entire design period of 20 years for all climatic zones without reaching this comparison level. The asphalt concrete reached this level in 10 years or more. A rut depth of 0.7 inch was chosen as the critical rutting level. For all four climatic zones, the asphalt concrete control reached the critical rutting level before the asphalt-rubber concrete; but both materials reached the critical level within the 20-year design period. Rutting was chosen as the expected critical failure mode for both materials in all zones. An equivalent uniform annual cost per square yard over the life of the pavement for the construction cost of each pavement was determined. The material with the least equivalent uniform annual cost was selected as the most cost-effective. Only in the dry-no freeze zone was the asphalt concrete more cost-effective than the asphalt-rubber concrete. In the other three zones, the low or medium (optimum) binder content asphalt-rubber concrete was the most cost-effective material.
