DALEY CORPORATION Daley Corporation meeting high production and quality expectations on San Diego’s Highway 76 project with new Volvo Highway-Class Paver By: Tammy Boone
Daley Corporation has nearly a century-long reputation as a builder of San Diego’s roadway infrastructure. The company’s latest contribution to that effort is as the asphalt lay-down sub-contractor for all HMA work on the Highway 76 widening and realignment project.

One of the challenges for Daley Corporation, Mark says, is the distance the HMA is being trucked—about 1-1/2 hours from an asphalt plant in Corona to the jobsite. “The length of the haul definitely affects the laydown. We have to take into account the number of trucks already on the road and know three hours in advance of stopping the trucks for the day,” he explains. “There is really no room for mistakes in either cost or quality.” It was with this job in mind that Daley Corporation purchased a new Volvo Blaw Knox PF6110 Track Paver in May 2011. “This machine is really designed for the paving
