ECO-MIX™, warm-mix asphalt (WMA) requires less energy to produce and uses more recyclable materials in the mix, making it a more sustainable product.
ECO-MIX™ has less oxidation during production, which means extended pavement life.
ECO-MIX™ reduces emissions, making it better for the environment.
ECO-MIX™ reduces and odor, making it better for your employees and customers.
In addition to these advantages, ECO-MIX™ is stored, transported, placed and compacted using the same equipment and similar procedures as traditional hot-mix asphalt. That means it can be installed with the same speed, efficiency and quality.
LEED Credits (Leadership in Energy and Environmental Design) were developed by the U.S. Green Building Council.
ECO-MIX™ is qualified for LEED Credits in the following areas:
The LEED certification process is overseen by the USGBC (U.S. Green Building Council). It is usually the general contractor or the architect who is responsible for getting the project certified; the asphalt contractor on a LEED project will interact with them and supply documentation of materials and processes beyond what is required for most jobs.

ECO-MIX™ uses a simple process that mixes water and asphalt cement (AC) to create microscopic steam bubbles to 'foam' the AC. The binder is foamed, much like shaving cream, using specialized injection equipment.
The foamed binder gives the liquid asphalt the same performance viscosity and volume characteristics at a lower temperature than traditional hot-mix asphalt.
ECO-MIX™ is stored, transported, placed and compacted using the same traditional procedures used for hot-mix asphalt.
ECO-MIX™ Asphalt delivers a superior pavement versus traditional hot-mix asphalt.
ECO-MIX™ requires less energy to produce, is 100% recyclable and is a sustainable product that is proven better for the environment.
Oxidation of the liquid AC binder leads to increased brittleness and loss of color. For every 25° rise in mixing temperature, oxidation doubles! With roughly 50°F lower mixing temperature, ECO-MIX™ has four times less oxidation, resulting in a greater binder integrity and a longer lasting pavement.
The foamed binder (AC) in ECO-MIX™ increases the lubrication of the mix which, in turn, reduces the viscosity. Lower viscosity allows for an easier, denser compaction and improved pavement durability.
Since the viscosity of ECO-MIX™ remains lower for a greater length of time, placement time is extended, ultimately resulting in higher quality pavements.
Traditional hot-mix asphalt depends on high temperatures to maintain proper workability. Thus, cold weather significantly impacts hot mix quality. Because of its foamed asphalt technology, ECO-MIX™ is less dependent on high temperatures and therefore less sensitive to cold weather. Using ECO-MIX™ slows the binder cooling time which results in successful paving during the early and late construction seasons.
Since ECO-MIX™ processes at a lower temperature, with less energy consumption, carbon emissions (CO2, NOX, VOC), are greatly reduced compared to traditional hot-mix asphalt. Emissions are lowered as much as 25%.
The light oils found in asphalt boil at temperatures above 285°F. By mixing Eco-Mix™ at lower temperature, the smoke vapor and smell are almost completely eliminated.
Asphalt pavement is 100% recyclable. ECO-MIX™ allows for greater percentages of reclaimed asphalt pavement (RAP) in the production mix, thus enhancing the overall sustainability of this paving material.
