Enhance the Performance of your Asphalt, Sustainably.
Powered by our proprietary Rapid Digestion Process™ (RDP), SigmaBond is an innovative asphalt modifier that enables hot mix contractors to use more upcycled materials while extending the life of pavements.
Main Benefits of SigmaBond
Safety
SigmaBond makes roads safer with darker, smoother pavements, enhancing the contrast of pavement markings.
Cost Savings
Using SigmaBond for all rubberized asphalt blends allows contractors to blend liquid asphalt with the required feedstock. This removes the need for any specialty equipment that other methods of TR inclusion would require.
Versatility
Engineered for any mix design. SigmaBond can be used in any application, and be emulsified with up to 10% rubber loading. Additionally, SigmaBond can be transported by rail or truck and mixed without specialized equipment.
Resiliency
With SigmaBond – pavements are better protected with superior resistance to the thermal cracking, UV oxidation and aging – improving road conditions.
Sustainability
SigmaBond enables faster production times and sustainable practices without compromising performance. Our formula reduces tire waste while extending the volume of existing PG grades and improving ΔTc.

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 rubber – pioneered this concept more than 70 years ago. McDonald’s camping trailer was leaking, and he needed a flexible material to effectively patch …
