With continued growth and success, Dunham’s Asphalt Services, Inc. built its asphalt plant in 2007 located in Sand Springs, OK at 8387 W. 21st Street. Today, Dunham’s plant serves not only our own asphalt pavement and maintenance crews, but also third-party customers such as city municipalities, county municipalities, and private customers. Our plant offers a variety of custom, hot-mix asphalt options pertaining to base and surface courses, as well as QPR 2000, otherwise known as cold patch.
