Asphaltica has been quietly working on improving Paving Pellets using RAS (Recycled Asphalt Shingles) and RAP (Recycled Asphalt Pavement) for several years now. Recycling waste materials in hot mixes have run the gambit from used asphalt to zeolite. They are often used as fillers to be disposed of in pavements i.e., walnut shells, glass, plastic, as well as dozens of other items and has been ongoing in the paving industry for decades. Some may actually help modify and improve the hot mix but often they do not warrant the additional cost or integrity compromise.

For several years Asphaltica has done extensive lab work and mix trials with both products but primarily focused on the enhancement of RAS as it has the capability to deliver improved performance and modification of the bitumen in the finished hot mix pavements. The pellets also increase rut resistance and anti-strip capabilities.

Asphaltica Paving Pellets are in full commercial production and have been successfully used in thousands of tons of hot mix in the Pacific Northwest in 2021 and pellet use will increase 10 fold in 2022.

Another reason Paving Pellets are the Right thing to do is because the pellets contain 26-28% recovered PG grade asphalt oil that would be destined for the landfill. At 5% pellet use in hot mix, the virgin oil demand is lowered by over 1%.

Our patents cover RAS, RAP and other products.  An ESG winner all around.

  1. Asphaltica currently has a large producer franchisee in the Pacific Northwest that is using the RAS pellets (ARP – Asphalt Recovery Pellets) to solve several of their concerns:
  2. Eliminate the handling issues of current ground RAS eg; feed rate problems and airborne fiberglass dust
  3. Transport and storage problems eg; clumping and moisture retention
  4. Adjusting mix designs to accommodate the “filler aspect” of shingles in the mixes

They also have benefited from the use of ARP:

  1. by increasing their useable oil content,
  2. improved mix rut resistance,
  3. improved mix anti-strip properties
  4. addition of crushed #4 material.
