The U.S. Army Engineer Research and Development Center (ERDC) conducted laboratory and field tests on several commercial-off-the-shelf cold patch asphalt repair products to determine their suitability for airfield pavement repairs. Testing included a suite of material property tests that were compared with results from full-scale field tests. Laboratory tests included determination of maximum theoretical specific gravities, compaction density, durability, workability, static creep, and dynamic creep. The field evaluation consisted of four repairs that were trafficked 24 hr after compaction under controlled traffic conditions to determine the ability of the repairs to support the gross load of an F-15E aircraft. Both the laboratory and full-scale traffic tests were conducted at the ERDC in Vicksburg, MS, from May to July 2009. Laboratory tests were evaluated to determine their suitability for a testing protocol to certify the use of cold patch materials for airfield asphalt pavement repairs. |
