Granite Construction recently opened its Big Rock Aggregate & Asphalt Plant in Llano, California.

According to Granite, Big Rock will provide aggregate and asphalt to private and public customers in northern and western Los Angeles, Ventura, Kern and San Bernardino counties.

The plant was built with safety and sustainability in mind, Granite says, using technology to produce 11 high-quality aggregate materials simultaneously with the flexibility to modify finished products as the market demands. The plant will also recycle 134,000 gallons of water per hour with a combination of dewatering screens, low-water washers and water clarifiers, the company adds.

Granite’s asphalt plant, meanwhile, optimizes the use of reclaimed asphalt pavement and warm-mix asphalt.

“Granite’s investment in our construction materials business demonstrates a commitment to aggregate and asphalt production in key markets across our vertically-integrated footprint,” says Brad Estes, vice president of construction and materials at Granite. “We expect Big Rock to fill a need for high-quality construction materials in the northern LA market for many years to come. We are pleased to bring this new plant online as part of our continued expansion in Southern California.”

Big Rock is Granite’s 76th materials facility. Granite’s construction materials business stretches across the Western U.S., and it specializes in recycling operations, aggregate plants and asphalt plants, which supply external customers and support Granite’s vertically integrated business.
