Staker Parsons always looks to incorporate new and innovative technologies into every project that they undertake. It is one of the reasons they are widely known as the "Preferred Source." This recent press release talk about one of the new and innovative technologies that Staker used down in Utah's Dixie a couple of years ago.
Cold Recycle Overlay in St. George, Utah
"Staker Parson Companies constantly strives to work innovation into each project it completes. In St. George, Utah, South Construction is working in partnership with Western Rock Products to complete an asphalt and paving job for the Utah Department of Transportation. The project, which started in January, extends from mile marker zero on the Utah/Arizona boarder to mile marker 6 at Bluff Street, in St. George Utah.
This project, however, is not like other asphalt and paving jobs. Because of UDOT requirements, crews are working with Cold Recycle Overlay with both Hot Mix Asphalt and Stone Matrix Asphalt. The process recycles 100 percent of the existing asphalt, saving existing resources. A portable crusher is pulled along the road by a roto-mill. The asphalt is milled and sent through the crusher with new oil being re-introduced, along with lime. Cold recycled asphalt is the result, and it is placed behind the equipment in a windrow on the roadway.
The lay down crew then picks the cold recycled asphalt and places the material like regular asphalt material. Crews have to wait for the moisture to dry out before they can place the final lifts of Hot Mix Asphalt. The final surface is placed and the cold recycle material becomes the base layer for the new roadway. The job also includes work on the bridges, the guardrails and the signs."
