Porous Asphalt: Improving Stormwater Management

Friday, February 24th, 2012

We have a new, powerful tool to help improve stormwater management and water quality: Porous Asphalt.

In nature, rainwater is absorbed by soil, filters through it, and eventually seeps into streams, ponds, lakes, and underground aquifers. In urban areas, rainwater falls directly  on cement and asphalt pavements and has nowhere to filter out harmful contaminants. As a result, those contaminants are washed into waterways without undergoing the filtration that nature intended.

This is where porous asphalt can help!

Porous asphalt has an open-graded (porous) surface over an underlying stone recharge bed, allowing rainwater to drain through the asphalt, into the stone, and then the soil. If contaminants were on the surface at the time of the storm, they are swept along with the rainfall through the stone bed. From there they infiltrate into the sub-base so that they are subjected to the natural processes that cleanse water.

Benefits of Porous Asphalt

•      Conserve water

•      Allow for better use of land

•      Reduce runoff

•      Promote infiltration

•      Clean stormwater

•      Replenish aquifers

•      Protect streams, ponds, and other waterways

Porous asphalt pavements are being used successfully throughout the United States, in every type of climate and geography. They are recognized by the Environmental Protection Agency as a best management practice for stormwater management.

Asphalt for Better Water Quality

An Overview of the Different Types of Asphalt

Friday, February 10th, 2012

Asphalt is the most versatile pavement material, with mixes designed to handle any size load (from passenger cars to heavy trucks), absorb noise, reduce splash and spray during rainstorms, and even to help treat rainwater. The different types of asphalt pavement include:

Warm-Mix Asphalt: This is the generic name of the technology that allows producers of hot-mix asphalt to lower the temperatures at which the material is mixed and placed on the road. This afford asphalt contractors many benefits, including:

•      Increasing safety for asphalt workers

•      Cutting fuel consumption

•      Decreasing the production of greenhouse gases

•      Better compaction of pavements

•      Extending the paving season

•      And the potential to be able to recycle at higher rates

Quiet Pavement: Today’s busy world is filled with more noise than one typically cares to deal with. But quiet pavement actually reduces the noise experienced both inside and outside homes and businesses. Resurfacing a noisy road with stone-matrix asphalt (SMA) or open-graded friction course (OGFC) mix can reduce noise by 3 to 5 dB(A) or more (the same as doubling the distance between you and the noise source).

Porous Asphalt: These pavement surfaces allow rainwater to drain through the asphalt into a stone recharge bed and then into the soil, eliminating potentially harmful standing water.

Perpetual Pavement: This advanced, multi-layer paving design process (along with routine asphalt maintenance) extends the useful life of a roadway.

Whether on the road, in a parking lot, or at an airport, asphalt pavements add up to the best value for your pavement needs, with the lowest life cycle cost and the highest residual value.
