Latest Green Asphalt Technologies Help Save Money and the Planet!

_______________________________________

Asphalt PavingAs summer and its corresponding construction projects are nearing an end, we are noticing – and appreciating – the improvements recently made on the roads, highways, and bridges we drive on every day.

Perhaps most notable are the roads that were repaired and likely re-paved in the recent summer months.  They provide us with a smoother ride and one with fewer bumps and potholes, not to mention a better alignment on our cars! But aside from the luxury of a fresh, new, smooth, safe, paved road, is the peace of mind of knowing that the asphalt used most often today – and what was used this past summer in the tens of thousands of paving projects that were completed across the U.S. – is “greener” than its ever been before!

Recent surveys and research conducted by the Federal Highway Administration (FHWA) and the National Asphalt Pavement Association (NAPA) reveal that Reclaimed Asphalt Pavement (RAP), Recycled Asphalt Shingles (RAS), and Warm-Mix Asphalt Technology (WMA) are all more environmentally-friendly than ever before.  In fact, with the increased use of the above-named asphalt types – RAP, RAS, and WMA – we can prevent over 1 million tons of CO² emissions from being released.

You can find further information on these green asphalt technologies below:

Asphalt Paving

Reclaimed Asphalt Pavement (RAP)

  • Nearly 100% of all RAP is either being reused or recycled in highway projects
  • 96% of asphalt-producing companies report using RAP
  • In 2009 & 2010, the overall use of RAP increased by 10%
  • The percentage of RAP found in the asphalt pavement material used by contractors and DOTs has increased to 17.6%, compared to 12.5% in 2005
  • On average, 77% of all reclaimed RAP is put toward the production of warm-mix, and all but .005% of the leftover material not used for warm-mix is recycled and used for highway shoulders & base
  • In many states throughout theU.S., base & intermediate pavement courses have been produced entirely with 100% RAP

Recycled Asphalt Shingles

Recycled Asphalt Shingles (RAS)

  • In 2009 & 2010, the use of RAS increased by 57%
  • Roughly 724,000 tons of RAS was used in 2009, while an astonishing 1.14 million tons was used in 2010 – ultimately resulting in the impressive 57% usage increase
  • The amount of RAS used in asphalt pavement production is about 10% of the total asphalt shingles available each year – which, on average, is to the tune of 11 million tons

Warm Mix Asphalt

Warm-Mix Asphalt Technology (WMA)

  • In just one year, the use of WMA saw an 182% increase.  In 2009, 16.7 million tons of WMA were used, while an incredible 47.2 million tons were used in 2010
  • WMA has been used in 47 of the 50United States
  • 29 states have WMA specifications
  • With its increased use, those who have opted to utilize WMA have discovered its many benefits, including the ability to extend the paving season into colder temperatures and climates, enhance compactability, lengthen hauling distances, reduce energy usage, and increase percentages of RAP used
  • The rate of utilization of WMA in the United Statesis more than any other country in the world

What’s more is that the green asphalt not only makes less of a negative impact on the earth, it makes less of a hole in our wallets, too!  Utilizing the recycling and warm-mix saves state DOTs and other public agencies a huge amount of money every year; also saved are precious natural resources.  Ultimately, the increased use of these materials provides workers with a safer, better, more comfortable workplace, and produces higher-quality, longer-lasting pavements at a much lower cost – all while simultaneously making a smaller impact on our planet.  Conclusively, we can all benefit from the use of green technologies.
