Over the course of placing 377,500 square yards of concrete for the $34.6 million repaving project on I-80, Geneva Rock implemented many sustainable elements: reducing and replacing cement content, using eco-friendly primer, recycling materials, and reducing waste disposal.
The cement-treated asphalt base was coated with ePrime, an eco-friendly primer, to retain moisture for curing, and help bond the base material with the concrete overlay.
Geneva Rock Products worked with Gomaco and Trimble to set up a wireless 3D paving system that performed paving techniques none of the companies had yet done wirelessly, including zero clearance paving.
Geneva Rock replaced 7.5 miles of asphalt roadway in Utah with a durable portland cement concrete pavement more suited to the region’s harsh climate changes. Here, a paver places concrete on the cement treated asphalt base, followed by the application of a white wax curing compound.
Before spring, the contractor added Trimble PCS900 paving controls to two of its four Gomaco slipform pavers, and employees learned how to remotely steer the pavers and use the SPS930 Universal Total Station to control the pan for proper alignment, design, and slope of the pavement.
ePrime is an eco-friendly primer, to retain moisture for curing, and help bond the base material with the concrete overlay.
A rebuilt section of I-80 in Utah won the 2016 Triad Award. The contractors, state DOT, and materials suppliers precisely coordinated the project timeline, executed challenging logistics, and improved the sustainability of this award-winning project.
Contractors used the Trimble SPS930 Universal Total Station to control paver alignment and precise pan placement using its 3D wireless paving system.
2016 Triad Award winners received custom-designed, etched concrete plaques and coasters. The pieces were created by Billy Losleben, designer and head of Concrete-Project, a creative firm that designs, develops, and produces unique concrete objects. See www.concrete-project.com.
