Staker Parson Materials & Construction recently completed a pavement rehabilitation project on I-80, from milepost 50 to 60, in Grantsville. This project required 40+ days for crews to remove the existing asphalt and place 47,000 tons of new Stone Matrix Asphalt (SMA) on the roadway surface. New lane striping and rumble strips were incorporated to enhance safety for travelers. Parking lot improvements were also made to two truck rest stops. The Utah Department of Transportation incorporated a new technique for rehabilitating the existing truck parking lot by concrete rubblization. The process was used to break concrete into particle sizes and remove the top 3”, regrade existing rubblized concrete and pave back 3” of asphalt.

Due to the project’s remote location, the team utilized 15 to 20 double-belly trucks to transport the material to the project site daily. This process ensured the successful placement of the SMA material and a smooth roadway surface. The team encountered challenges paving SMA, as opposed to the traditional HMA.
