当客户规格允许时，奥斯汀桥 & 道路使用再生沥青路面(RAP)和再生沥青瓦(RAS)积极生产热混合沥青(HMA)。. 在材料再利用方面，奥斯汀桥 & 路 reduces consumption of virgin oil required in HMA production; reduces consumption of virgin aggregate required in HMA production; reduces overall asphalt plant energy consumption; reduces waste sent to landfills; and reduces fuel emissions and road congestion.

为此目的, 奥斯汀使用最大允许的再生沥青产品生产国家认证的道路和高速公路沥青. In 2022, 奥斯丁 used more than 275,000 tons of recycled products; a 6% increase year-over-year vs. 2021.
