PREVENTION OF REFLECTIVE CRACKING IN ARIZONA MINNETONKA-EAST (A CASE STUDY)

In conjunction with a thin overlay (1-1/4" AC and 1/2" ACFC) 18 test sections consisting of various treatments were built in 1971 and 1972 to determine to what extent they prevented reflective cracking. From these 18 treatments five were found to significantly reduce reflective cracking. These treatments were: (1) Heater scarification plus petroset; (2) Asphalt rubber membrane interlayer; (3) Fiberglass; (4) Heater scarification plus reclamite; and (5) 200/300 penetration asphalt. Besides cracking other performance values including roughness, rutting, deflection and asphalt properties are reported. Costs in terms of construction and actual maintenance are given. From all of the above each treatment's mechanism of failure or success is reviewed and considered in determining the conclusions and recommendations. /FHWA/
