PERFORMANCE EVALUATION OF NOVACHIP (TRADEMARK): ULTRATHIN FRICTION COURSE. FINAL REPORT

NOVACHIP (Trademark) was successfully constructed on two highways in the San Antonio District of the Texas Department of Transportation: US 281 and SH 46. A NOVACHIP (Trademark) friction course consists of a layer of hot-mix material placed over a heavy polymer-modified asphalt tack coat. The course thickness ranges from 10 to 20 mm. Layer thickness is typically 1.5 times the diameter of the largest stone. The French process, NOVACHIP (Trademark), is a new technology for Texas and the United States. This research study was created to provide a field evaluation and documentation of the process and resulting performance. After three years of service, the NOVACHIP (Trademark) pavement surfaces are in excellent condition. NOVACHIP (Trademark) shows promise as a preventive maintenance treatment or surface rehabilitation technique for asphalt concrete pavements. It should provide the maintenance engineer with an alternative for chip seals, micro-surfacing, plant-mix seals, or thin asphalt concrete overlays.
