Warm Mix Asphalt (WMA)

Warm Mix Asphalt (WMA) is an environmentally friendly alternative to HMA, requiring lower temperatures for mixing and application. This reduction in temperature, typically 20 to 40 degrees Fahrenheit lower than HMA, results in fewer emissions and reduced energy consumption. These benefits make WMA a more sustainable choice for many projects.

Besides its environmental advantages, WMA can also be easier to work with under certain conditions. The lower temperature range can prolong the working time of the asphalt, allowing for better compaction and smoother finishes. Thus, WMA presents a viable option for projects aiming to reduce their carbon footprint while maintaining high quality.

Porous Asphalt

Porous asphalt is designed for effective stormwater management. It incorporates a mix of coarse and fine aggregates, allowing water to drain through the surface into a stone recharge bed beneath. This feature makes porous asphalt an excellent choice for parking lots and other areas where water drainage is a concern.

The benefits of porous asphalt extend beyond drainage. Properly installed, it can last over 20 years, contributing to groundwater replenishment and reducing the burden on storm sewer systems.

Despite its advantages, it’s important to maintain porous asphalt to prevent pore blockage from debris, ensuring its long-term effectiveness.
