Evaluation of New Patching Material for Open-Graded Asphalt Concrete (OGAC) Wearing Courses

A free-draining, easy-to-use patch material was evaluated in order to determine if it could be successfully used to patch holes and pop-outs in open-graded asphalt pavements. FloMix, an off-the-shelf patching product from Roklin Systems Inc., was modified to produce a free-draining, fast-setting matrix of aggregate and polymer. This modified patch product was then placed at two test sites were its workability and durability were assessed. The product was found not durable in the more severe field trial.
