Historic RAP plant-produced hot mix asphalt projects

Products | Baker Rock Resources | Asphalt Paving and Aggregate

We produce BRR high performance cold mix asphalt, which uses the latest polymer additives to enhance pliability and work-ability especially designed for our local climate. We utilize recycled asphalt pavement (RAP) to the fullest extent permitted by public agencies since Asphalt itself is recyclable.
