Experimental Overlays to Minimize Reflection Cracking
California's research on experimental asphalt concrete overlays to minimize reflection cracking has been in progress since 1971. An evaluation of various methods and systems is being made to determine their effectiveness in reducing reflection cracking in bituminous overlays. The purpose of this interim report is to present information on the construction of the experimental overlay projects and to report on their performance to date. An additional 0.12 foot AC placed in conjunction with a 0.08 foot maintenance blanket (0.20 foot total) is performing better than the experimental test sections on a project with thermal cracking. On two projects in Southern California with alligator cracks 1/8 inch wide or narrower and visible signs of pumping in the surfacing, the use of Petromat has extended the life of a one inch overlay by more than two years.
