Maryland Paving produces and hauls hot mix asphalt, which is loaded into its trucks at a piping 325 degrees, and superpave. It offers various mixes, including base and surface, and the amounts of stone and sand in the mixes vary depending upon the application. Maryland Paving, which was founded in 1965, does not handle road paving (its parent company, Gray and Son, does), but its product is sold to the state, county and public.
