Evaluation of the Effectiveness of Membranes for Prevention of Crack Reflection in Thin Overlays.
Abstract
This report is an interim report resulting from case studies of pavement performance conducted by the U. S. Army Engineer Waterways Experiment Station under contract order with the U. S. Army Forces Command. The purpose of this study was to determine if a stress-absorbing layer consisting of an asphalt-rubber membrane or a nonwoven fabric placed under a thin asphaltic concrete overlay (2 in. or less) will stop reflection cracking from occurring in the overlay. Field tests of two asphalt-rubber membrane formulations and three nonwoven fabrics were placed on roads and airfield pavements at five Army installations in various areas of the United States. This report covers the construction of the test areas and performance after a 6-month period. A final report will be prepared on the performance of each material after a number of years of annual inspections. (Author)
