Project: FDR in Madera County
Madera County recently completed the 2020 Countywide Pavement Rehabilitation with an Overlay Project on approximately 26 miles of roadway. The project included work on Robertson Boulevard between Avenue 18 and SR-152, Road 16 between SR-152 and Avenue 25, and Avenue 9 between Road 38 and Children’s Boulevard. Madera County awarded the approximately $8.6 million project to Don Berry Construction out of nearby Selma. Don Berry Construction subcontracted the milling and full-depth reclamation portion of the contract to Pavement Recycling Systems.
We began in July 2021 by pre-pulverizing the existing three-to-four inches of asphalt. Our PRS crews mixed this existing asphalt on grade with the soil subgrade below to Madera County specifications. This process made for a very stable subgrade, as we began mixing water and cement at 4 or 5 percent to a depth of 1 foot 2 inches to 1 foot 5 inches.
We completed 8 to 9 thousand square yards or approximately 3/4 of a mile of full-depth reclamation each workday. “We used our Wirtgen WR 240i Cold Recycler and Soil Stabilizer, along with a spreader truck, compactor, and several water trucks. We ran with two crews on some of the sections to increase production, so that required two Wirtgen Cold Recycler and Soil Stabilizers and two spreader trucks.”
