The Contracting division’s commitment to innovation and quality has provided opportunities for our customers to integrate environmentally-conscious practices on the jobsite. The design, material processing, and production of these practices are both environmentally responsible and resource-efficient during the construction phase.
Warm Mix Asphalt
Warm Mix Asphalt incorporates the use of an additive to allow a reduction in the temperatures at which asphalt mixes are produced and placed. WMA is expected to produce somewhere around 15-30% reduction in fuel use/emissions at the plant and during lay down. WMA asphalt can be placed in cooler temperature conditions often found at night, early and late in the paving season, and during changing weather conditions.
A “Greenroad” is defined as a roadway project that has been designed and constructed to a level of sustainability that is substantially higher than current common practice. The Greenroads rating system is a sustainability rating system for roadway design and construction projects. Points are awarded for sustainable design/construction, similar to LEED certification for green buildings. The rating system is managed by Greenroads Foundation, a third party non-profit corporation. There are over 120 projects rated around the world, most completed during five years of research/development at the University of Washington. There are currently 50 registered projects, mostly in the western US, as well as Texas, Michigan, Colorado, North Carolina (Charlotte, Raleigh, and Fayetteville), and Canada. Carolina
