High-End Residential Development Showcases Road Reconstruction

"By closing the road off in four phases, we were able to accelerate the new construction and the reclamation work, cutting the overall construction time by 50 percent," Edwards says. "The developer wanted to meet all DOT standards in reconstructing the road, but he also wanted the road finished in time for the spring opening. As a result of using FDR on the existing asphalt roadway rather than patching distressed segments of pavement and closing the road to traffic during construction, we were able to complete the project in 75 days rather than the 150 original construction days specified in the contract."

During the phase construction, Site-Prep's FDR crew was able to complete work within three to four days, and Rea's paving crews placed a new binder course within one to two days.

"The FDR approach was an easy sell to the developer, because it involved recycling existing asphalt, and The Sanctuary is a 'green' development," Edwards says. "The DOT also liked the FDR approach because it produced a consistent base for a new overlay and patching distressed sections would not have done that."

The cost of reclamation and a new HMA overlay produced a 21 percent savings over the original proposal to patch and overlay.

"The entire project cost 40 percent less than a conventional reconstruction, and I think the DOT and developer are happy with that," Edwards says. "Morgan, Rea and Site-Prep partnered with the owner and DOT to provide a lower cost, higher quality project with a lesser impact to existing traffic flows by recommending the FDR solution over conventional patch and resurfacing construction."

About Site-Prep

Site-Prep Inc. of NC, founded in 1991, performs construction services as a subcontractor for highway construction firms in the Carolina, Virginia, Georgia and Tennessee. Site-Prep works primarily as a soil and base stabilization, and asphalt reclamation contractor, but also does extensive work in the field of stone base and roller compacted concrete work.

Site-Prep has aggressively promoted asphalt reclamation as an innovative and cost-saving approach to roadway maintenance, and anticipates continued growth in the preservation concept as more road agencies experience the benefits it offers. Site-Prep currently operates four full stabilization crews year-round and often adds a fifth crew during the peak construction season.
