Illinois' largest pavement patching company, G.M. Sipes Construction Co., Rushville, Ill., replaces an average of 50,000 to 60,000 tons of pavement annually, leaving the company with a lot of concrete and asphalt rubble to dispose of. Trucking costs, tipping fees, and the increasing scarcity of landfill space convinced the company it had to reduce these disposal costs, so in 1997 it formed a subsidiary, Interstate Recycle Corp., Springfield, to process pavement rubble from G.M. Sipes construction jobs throughout the state. As word of the company's capability got around, it began recycling other contractors' rubble as well as ready-mix producers' leftover concrete.
When recycling concrete, Interstate uses a Grasan KR1010 rubble plant and a Grasan 5x10 road-portable screening plant sized for the KR1010 crusher. The company chose the small, highly mobile plant because it could be set up quickly in cramped quarters and could handle small to medium-sized projects efficiently. Interstate uses the minicrusher to process as much as 300 tons of rubble per hour.
