TxDOT reclaims and reuses about one million tons of recycled concrete pavement (RCA) annually. Our suppliers crush and separate the material into several grades of hard, granular mineral aggregates suitable for various applications. On some projects, contractors crush, or rubblize, pavement in place to save the cost of transporting the material.
Reusing concrete provides significant environmental and economic benefits. Dumping concrete wastes landfill space and material. Reusing one million tons of RCA in new concrete pavement reduces greenhouse gas emissions by the equivalent of 46,000 metric tons of carbon dioxide.
