Q: What is RAS?
A: Recycled Asphalt Shingles
Using Waste Shingles for Stabilization or Dust Control Roads and Shoulders
Before
After
How it works.
• Contact us ahead of time with bundle count.
• Roofer brings their shingles bundles to our location (2503 Dudley Street) to drop off.
• We use our machine to grind up shingles (off site)
Environmental Benefits
• Diverts non-degradable material from landfills
• Conserves 2 barrels of oil per 1 tonne RAS in pavement
• Reduces greenhouse gas emissions
Recycled Asphalt Shingles (RAS) include both manufacture waste scrap shingles (MWSS) and post-consumer tear-off scrap shingles (TOSS).Some agencies have used dust-control additives to help the performance of these lower-quality gravels. Successful implementation has the potential of removing valuable RAS materials from the waste stream to supplement the use of more expensive virgin materials and improve the performance of local roads.
A Proven Concept
Being that asphalt shingles represent a major and non-degradable waste stream in landfills, we'd like to move that from the landfill to roads as dust control for a better option than conventional means.
Why Now?
Prices
• Increases in tipping fees at landfills
• Increases in crude / asphalt cement
prices creating a demand for RAS
• Green to be green
Crisis
• Imparts a sense of urgency
• Global warming, now a known fact, an
accepted reality
• Landfill space issues
• RAS helps create safer dust-free gravel roads
What do people say about RAS?
Hello Len
My experience with Calcium Chloride (CC)
that is used as dust control from the
perspective of a fleet owner is poor at best.
In the past, there has been few alternatives
that satisfy both land/ home owners,
unhappy with the consequence of truck
traffic, and truck owners and drivers. The
CC does provide dust control however, it
creates a slippery mucky surface that can
prove treacherous in certain situations. As
well, the CC sticks to everything when
driven on. This diminishes the effectiveness
with every pass as well coats the underside
of every vehicle with it. This proves costly to
wash off and if left unchecked, creates a
considerable smell. I believe your
alternative will prove to be both cost
effective and user friendly
Thanks

The Town of Aberdeen was one of the first
towns in Saskatchewan to use this product.
We used it as a cost saving method over
calcium chloride. We found that not only was
it a dust controller but offered a sound
barrier that we didn't expect. When you have
long periods of no rain we have chosen to
water it down. We found that mixing gravel
and RAS product was the most effective
way to use it and allow long term
sustainability. We are happy with the
outcome as well as how it packs hard like an
asphalt.
