Scott Construction Inc., Lake Delton, Wis., is one of Wisconsin’s leading asphalt surfacing companies, and the largest chip seal contractor in the state. To support the amount of chip seal work the company performs throughout Wisconsin and Minnesota (regional suppliers couldn’t keep up with the demand), the company began mining granite out of the new Pine Valley Quarry (Neillsville, Wis.) in 2015.
With the new quarry, Scott Construction can control quality and access to its chip seal products. The company shoots raw granite and crushes it down down to 5/8-inch minus, and then screens it and crushes it down again to ½-inch minus. The company then washes that and crushes it down to 3/8-inch and ¼-inch minus product. The remaining byproduct is then used for hot mix and concrete.
