Harmonizing the Hallmarks of Sustainable Pavements

In many sectors, including the asphalt pavement industry, sustainable materials are coming into play and are at the top of everyone’s agenda. Recycled asphalt pavement and shingles (RAP/RAS), waste tire rubber (WTR), plastics, glass – many scrap products find viable end uses in pavements. But focusing on materials alone is…

The Evolution of Waste Tire Rubber in the Greening of the Asphalt Industry

The greatest innovations often have the most humble beginnings. So is the story of the use of waste tire rubber in asphalt pavements. Charlie McDonald – dubbed the father of asphalt rubber1 – pioneered this concept more than 70 years ago.  McDonald’s camping trailer was leaking, and he needed a…

Good Binders Make RAP and RAS Better

As more DOT specifications call for increased percentages of recycled materials in asphalt hot mix, many still need to be convinced about the performance of pavements paved with RAP and/or RAS. Additionally, there’s confusion over the environmental and financial impact of using recycled materials. These are all valid concerns.  However,…

Independent Studies Prove that SigmaBond Results in Upcycled Performance

Focusing on what's possible is at the core of everything Polyco does. One of the innovations we are most excited about is the technology we’ve developed to reduce landfill waste by recycling waste tires. While there are many ways to recycle tires, Polyco’s patented Rapid Digestion Process (RDP) completely liquefies…

Highlights from the August 2022 AASHTO Committee on Materials and Pavements (COMP) Meeting

Last week, I had the pleasure of attending the AASHTO Comp meeting on materials and pavements. If you haven’t heard of AASHTO, it’s the American Association of State Highway and Transportation Officials. AASHTO has a set of specifications and testing procedures for all materials that go into state DOT public…

The Sustainable Benefits of Terminal Rubber Modified Slurry Seal (TRMSS)

In my last post, we outlined the nuances between different types of slurry seals. In this post, we’ll take a closer look at the benefits of terminal rubber modified slurry seal (TRMSS) and the significance of it for our partners in California. Using up to 80 percent more aggregate per…
