The Use of Fabric Reinforced Overlays to Control Reflection Cracking of Composite Pavements
Report No: 72-R27
Published in 1973
About the report:
Fabric reinforcement was used in an attempt to prevent reflection cracking of two bituminous concrete layers overlying an 8-inch plain (unreinforced, unjointed) concrete base that was underlain by a portland cement stabilized subbase material. On these pavements it was expected that the extremely rigid base and subbase layers would reduce vertical motion to a minimum. Similar pavements constructed with no overlay reinforcement readily showed reflection cracking in the bituminous layers, presumably because of horizontal, thermally induced movements of shrinkage cracks in the concrete base.
