For decades, Interstate Asphalt has served its customers by providing the highest quality neat liquid asphalt products ON SPEC, IN STOCK, ON TIME, EVERY TIME. Our terminals have over 250,000 liquid tons of total capacity, and have the ability to store, blend and transport liquid asphalt by barge, rail and truck throughout the Great Lakes region. The terminals we utilize store and ship many of the same performance grade asphalt products so that in the event of planned maintenance or unplanned shutdown, we can still support our customers' needs.
