Recycled Asphalt Tear Off Shingles (RAS)

EnergySmart contractors are being encouraged to recycle any tear-off shingle waste from local projects...


Unfortunately, because of increased recycling volume of shingles, lack of space and limited market demand for RAS, Asphalt Specialties has closed down their recycling operations in Erie and at all their other Denver Metro locations as of 5/28/11, until further notice.

At this time, only Brannan Sand and Gravel, at 61st and Pecos, and Owens-Corning/Heritage Environmental at 64th and Pecos, both in Denver, are receiving tear off shingles for recycling.

New Opportunities for the Use and Promotion of RAS

Though Boulder County tear off shingle recycling operations are now largely curtailed by the shutdown of Asphalt Specialties local collection point, there are other encouraging developments for the eventual end use of RAS in large scale paving projects:

*In March of 2011 The Colorado Department of Transportation approved a revision of Section 401, Reclaimed Asphalt Shingles, which modifies CDOTs Standard Specifications for Road and Bridge Construction (in practical terms this means 10,000 to 20,000 tons of RAS may be used in CDOT approved paving projects this year).

*Asphalt Specialties has been awarded a contract to pave portions of State Highway 36 using a recycled asphalt pavement (RAP) and RAS mix design (the RAS portion shall be manufacturer scrap shingle stock in lieu of tear off shingles). More detail is provided below.

* A formal discussion with Lisa Friend and Jeff Callahan of Boulder County Resource Conservation Division and other recycling contractors occurred in April of 2011. This discussion helped with the gathering of initial information for a proposed feasibility study for the opening of a county Construction and Demolition Waste recycling facility which will include RAS and other construction material.

* The Colorado Springs Chamber of Commerce Sustainability Action Council brought a group of 40 – 50 members of their business community and local government to Boulder County in April with an aim to learn more about our sustainability practices in the public, private and non-profit sectors. This exchange brought about productive dialogue with our Colorado Springs counter parts and how best practices in Boulder County may be useful models for our neighbors to the south.

Moving Forward with the RAS Initiative in Boulder County

Recycling asphalt tear off shingles that come from the City and County of Boulder is now less practical due to the Closing of Asphalt Specialties collection point in Erie.
However, there will be some tear off shingle materials coming from Boulder County that go to either Brannan sand and Gravel or Owens-Corning/Heritage. Among those who will make an effort to recycle some loads are 3R Roofing, Van Lier Roofing and Haul Away Recycling and others.
Denver based contractors are still very active in their recycling efforts as these collection point locations are within reasonable distance of their job locations. As CDOT approves the use of RAS in more large scale road projects the value of this commodity will increase. Boulder County based collection points, with increased demand and the rising cost of asphalt based products will eventually see more movement of RAS out of current stock piles. In a matter of a few years and with CDOT actively supporting its use, RAS will be a common commodity in large and small scale paving projects in Colorado.
As this market matures, it will be practical to re-introduce a Boulder County administrative mandate and also to consider public/private partnerships for the collection and sale of asphalt tear off shingles for road paving.
