Recycling asphalt shingles reduces the need to mine and process new raw materials conserving water oil and aggregate Saves Energy Producing asphalt shingles from scratch is an energy intensive process The binder has to be heated to extremely high temperatures and the aggregate dried and mixed using natural gas and electricity
Recycling asphalt shingles are a great way to reuse the materials that make up your roof Asphalt does not decompose quickly making it an excellent candidate for reuse Recycled asphalt shingles can be used in road construction or even for fuel Roofing contractors typically remove shingles from homes and haul them to recycling centers
USE OF RECLAIMED ASPHALT PAVEMENT AND RECYCLED ASPHALT SHINGLES IN ASPHALT MIXTURES The practice of utilizing reclaimed asphalt pavement RAP and recycled asphalt shingles RAS in new asphalt mixtures has increased in recent years because of its economic and environmental benefits RAP has already become one of the most widely used
Each year in the roughly 13 million tons of asphalt material gets torn off of old roofs to make way for new asphalt shingles Currently only about 10% of that tear off gets recycled for use in paving and other roadway projects That leaves about 12 million tons of waste to get shipped to landfills each year
5 Since 2011 North Carolina paving companies have been able to use clean post consumer recycled asphalt shingles PRAS as feedstock material in hot mix asphalt on North Carolina Department of Transportation DOT road projects Asphalt shingles are considered clean if metal wood insulation flashing and other trash are removed
Currently the closed loop recycling of asphalt shingles creating new shingles from old shingles is still in developmental stages and the most common practice is open loop recycling with recycled shingle use in HMA Therefore WARM assumes that all recycled shingles are used to replace virgin asphalt and aggregate material WARM assumes a 22%
Pictured at right Tear off shingles that have been processed to 3/8″ / 9 mm minus for use as a hot mix asphalt paving Starting a RAS operation from the ground up In June of 2008 when Krueger contacted his Rotochopper sales rep asking about asphalt shingle recycling and the RG 1 shingle grinder all he had was an idea a few tons of shingle
Given the wide use of reclaimed asphalt pavement RAP and the increasing use of recycled asphalt shingles RAS in asphalt mixtures the Transportation Research Board Committees on Characteristics of Nonasphalt Components of Asphalt Paving Mixtures Characteristics of Asphalt Materials and General Issues in Asphalt Technology jointly
Studies have shown that using recycled materials such as recycled asphalt shingles RAS reduces the environmental impacts related to extraction transportation and processing of virgin materials [2] Different recycling agents RAs may also be used in the asphalt mixtures containing RAS to improve the blending between recycled and virgin materials [3]
Replacing virgin materials with recycled asphalt shingles RAS saves resources reduces the energy burned from using raw materials eases landfill pressures and reduces the demand of extraction [4] [5] Using RAS in asphalt pavements can also reduce greenhouse gas emissions produced during road construction by 9 12% [6]
The recycling of asphalt shingles in pavement construction is beneficial to the environment and industry by reducing the consumption of virgin materials However current approaches of utilizing recycled asphalt shingle RAS by mixing with soft asphalt or rejuvenator were questionable for the anti aging problems This study developed a new
The price of asphalt binder has increased from nearly $176 per ton in 2004 to $455 per ton in 2018 [1] Due to the overall increase in the price of asphalt binder and depletion of crude oil sources substituting a portion of asphalt binder with the binder available in Recycled Asphalt Shingles RAS has been promoted [2] In the United States about 14 percent of the
The recycling of asphalt shingles in pavement construction is beneficial to the environment and industry by reducing the consumption of virgin materials However current approaches of utilizing recycled asphalt shingle RAS by mixing with soft asphalt or rejuvenator were questionable for the anti aging problems
Since almost 15 35% of recycled asphalt shingles RAS consist of an asphalt binder the effective recycling of RAS into asphalt mixtures could also allow a reduction in the consumption of non
Recycled or Reclaimed Asphalt Shingles RAS is a technology that holds promise for reduced impacts on landfills reducing asphalt costs and enhancing pavement performance However the manner in which RAS influences certain pavement properties has not been well documented and many questions
USE OF RECLAIMED ASPHALT PAVEMENT AND RECYCLED ASPHALT SHINGLES IN ASPHALT MIXTURES The practice of utilizing reclaimed asphalt pavement RAP and recycled asphalt shingles RAS in new asphalt mixtures has increased in recent years because of its economic and environmental benefits RAP has already become one of the most widely used
Eight types of recycled asphalt mixtures for surface course were investigated Those mixtures were produced with two virgin binders PG 64 22 and PG 70 28 It was founded that the recycled asphalt mixtures with a PG 64 22 binder showed improved fatigue performance with 30% RAP or a blend of RAP and RAS compared to the control mixture
Recycled asphalt driveways cost $ to $ per square foot including comparison standard asphalt costs $7 to $13 per square foot including of the rising price of oil standard asphalt costs considerably more Gravel for comparison costs $ to $ per square foot including If you need to remove
When it is time to replace worn out asphalt shingle roof request the shingles be recycled by Falcon Green Resources We are the first shingle recycler in Illinois since 1999 giving us the experience to produce superior end market type 1 and type 2 recycled asphalt shingles
Benefits of Recycling Asphalt Shingles Recycling aluminum glass plastic and paper has a positive impact on the environment—the same is true for asphalt shingles There are a few key benefits to recycling old asphalt roof shingles Reduces CO2 emissions According to the National Asphalt Pavement Association NAPA asphalt recycling is
When it comes to recycling/repurposing asphalt roof shingles and production scraps the roofing and asphalt industries have put their money where their mouths are by finding ways to use these materials in several asphalt related applications It is generally accepted that at least 11 million tons of old asphalt shingles are removed from American rooftops annually […]
