SUSTAINABLE PRODUCTS INTEGRAL TO OUR BUSINESS

The asphalt pavement industry in California, working in conjunction with researchers and public owners, is moving aggressively toward a new pavement standard, "Warm Mix Asphalt," which promises many benefits, including reducing the consumption of fuel used to heat conventional Hot Mix Asphalt and widening the "window" for transporting and placing asphalt.

 

Our Warmpave™ asphalt paving material requires less energy to produce, contributes to sustainable development and helps our customers achieve their green building initiatives. Tests have confirmed that Warmpave™:

 

• Reduces direct carbon dioxide (CO2) emissions, the primary greenhouse gas, by more than 20%

 

• Uses less fuel to produce and thus CO2 emissions are further reduced

 

• Significantly reduces other emissions such as oxides of nitrogen (NOx), by 40%

 

WarmPave™ asphalt allows Vulcan Materials to lower temperatures at which the material is mixed and placed on the road. Reductions of 50 to 100 degrees Fahrenheit have been documented. Such drastic reductions have the obvious benefits of cutting fuel consumption and decreasing the production of greenhouse gases.

 

In addition, research at the National Center for Asphalt Technology and elsewhere has shown that lowering the production temperature can drastically reduce the production of emissions. By cutting emissions, warm-mix asphalt improves conditions for workers and enhances relationships with neighbors.
