From quarry to road

摘要

Scott Construction Inc. 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, the company began mining granite out of the new Pine Valley Quarry (Neillsville, Wis.) in 2015. With the new quarry, Scott Construction could begin controlling quality and access to its chip seal products. The company shoots raw granite and crushes it down to 5/8-in. minus, and then screens it and crushes it down again to 1/2-in. minus. The company then washes that and crushes it down to 3/8-in. and 1/4-in. minus product, respectively. The remaining byproduct, not gone to waste, is then used for hot mix and concrete.
