Laboratory Evaluation of Selected Fabrics for Reinforcement of Asphaltic Concrete Overlays
Asphaltic concrete overlays are often used in an attempt to restore the riding quality of a roadway and extend its useful life. However, these overlays are susceptible to premature deterioration as a result of transverse reflection cracking, whereby a cracking pattern existing in the original pavement is extended into and through the new overlay. Various 'engineering' fabrics have been used in recent years to provide reinforcement and undersealing for overlays in attempting to prevent and/or delay the occurrence of reflection cracking, and the subsequent penetration of water into the sublayers. Six commercially available engineering fabrics were tested in an effort to develop a reinforced overlay design. Laboratory and theoretical studies indicate that the addition of an engineering fabric, in combination with a tack coat of asphalt cement, can greatly increase the resistance of an asphaltic concrete overlay to reflective cracking.
