Heatwurx Patching at Two Locations in San Antonio (5-9043-01-1)

Patching asphalt pavement is an important, necessary part of TxDOT operations. Cracked and failed areas need to be replaced by high quality, sound pavement in order to meet the needs of the traveling public. This report documents the placing, cost, and performance of the HeatWurx™ pavement patching process, which uses infrared heating to make the pavement soft enough to mill and scarify so that it can be mixed with a rejuvenator and pavement millings to form a patch that stays bonded to the surrounding material. A total of 83 4 ft by 8 ft patches were placed.
