Black is the New Green :: Asphalt Pavement and Sustainability

Friday, August 24th, 2012

As Americans become increasingly concerned with the concept of Going Green, environmentally sustainable pavements are also rising in popularity. Fortunately, the asphalt pavement industry has been working for decades on making its pavement greener.

  1. Asphalt is America’s most recycled material.
  2. Asphalt is the most sustainable and environmentally-friendly pavement on the market.
  3. While production of asphalt pavement material increased by 250% between 1960 and 1999, total emissions decreased by 97%.
  4. Warm mix asphalt reduces the demand for energy in the production and construction of pavements.
  5. Asphalt is a low carbon footprint pavement.
  6. Asphalt pavement has a long life & resurfacing is quick.
  7. Porous pavement helps improve stormwater management.

From production to paving to rehabilitation to recycling, asphalt pavements minimize impact on the environment.

Can Asphalt be Recycled? My Pavement Guy Answers Frequently Asked Questions

Friday, July 13th, 2012

Not only can asphalt be recycled, but it is America’s most recycled and reused material, with about 70 million tons of asphalt pavement material being reclaimed! In fact, asphalt is being recycled and reused at a rate over 99 percent, which is amazing, especially when you consider that 94% of the paved roads in America are surfaced with asphalt.

A study conducted by the National Asphalt Pavement Association – titled Asphalt Pavement Mix Production Survey: 2009-2010 (NAPA Information Series 138) – examined the use of reclaimed asphalt pavement (RAP), recycled asphalt shingles (RAS), and warm-mix asphalt (WMA) between 2009 and 2010. The report found that RAP, RAS, and WMA…

  1. Conserve raw materials
  2. Conserve energy
  3. Cut emissions from production and paving operations
  4. Improve conditions for workers

Asphalt, The Sustainable Pavement

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.

Types of Asphalt Pavement

Recycled Asphalt Pavement: What You Probably didn’t know About Asphalt

Wednesday, January 25th, 2012

Here is something you probably don’t know about asphalt. It is America’s most recycled material. That’s right. Not aluminum cans or plastic bottles…asphalt! In fact, asphalt pavement is now being recycled and reused at a rate over 99%. In 2010 alone, asphalt recycling conserved over 20.5 million barrels of asphalt binder.

Here are a few highlights from the National Asphalt Pavement Association’s (NAPA) report titled, Asphalt Pavement Mix Production Survey: 2009-2010 (NAPA Information Series 138):

Reclaimed asphalt pavement (RAP): With 96% of asphalt contractors and asphalt companies using RAP, the amount of RAP used in asphalt pavement was 56.0 million tons in 2009 and 62.1 million tons in 2010. This represents over 3 million tons of asphalt binder conserved over that time.

Warm-mix asphalt (WMA): Total tonnage of WMA is estimated at 19.2 million tons in 2009 and 47.6 million tons in 2010, a 148% increase in that one year alone.

RAP and WMA conserve raw materials; conserve energy; cut emissions from production and paving operations; and improve conditions for workers.

The Benefits of Warm-mix Asphalt

Wednesday, April 6th, 2011

Warm-mix asphalt has been called the wave of the future, but what is it? Well, it is actually a generic term for several techniques used to reduce the temperature, by as much as 50 to 100 degrees, at which materials are mixed and placed on the road. This article from WarmMixAsphalt.com seeks to better explain this revolutionary new technology.

This drastic reduction in temperature has not only slashed fuel consumption, but it also reduced the production of greenhouse gasses, improving conditions for workers by cutting down on dangerous emissions. Warm-mix asphalt also allows for better asphalt compaction on the road, the ability to haul paving mix for longer distances, and the extension of the paving season.

But there are still several questions that must be answered before we crown warm-mix asphalt as the king of the road.

  • Can warm-mix pavements be opened to traffic quickly after construction?
  • What are the performance characteristics of these pavements?
  • In the case of technologies developed in other countries, can they be adapted to the U.S., where climate conditions are often more extreme?
  • If the production temperature is lower, does that mean that the binder does not age as much?
  • Will the potential for thermal cracking be reduced?
  • Will the potential for rutting be different?
  • Will the contractor have to use a different grade of asphalt binder?
  • What changes for the mix design procedure will be required?
  • Will the performance-graded binder in a warm mix perform differently from pavements produced at higher temperature?
