SigmaBond Performs Across the Country
SigmaBond has been rigorously tested to ensure long-term performance. Time and time again, SigmaBond has been proven to significantly enhance fatigue resistance and thermal stability.
- On NCAT’s test track, PG76-28SR binder mixed with SigmaBond at 20%+ TR and 20% RAP resulted in no cracking after ~2 million ESALs and < 5mm of rutting.
- An independent study by the University of Nevada, Reno found that SigmaBond samples with 10% tire rubber significantly increased cycles to fatigue, resulting in a 10% – 25% reduction in construction cost per lane-kilometer.
- Binder tests performed at Polyco’s R&D facility showed resistance to thermal cracking, reduced block or fatigue cracking and a drastic improvement in low temperature performance.
High-traffic performance in Southern California
A busy Santa Ana roadway was repaved in 2014 using a slurry seal incorporating SigmaBond in its TRMSS emulsion. Nearly a decade later, the SigmaBond slurry seal remains intact despite heavy traffic volumes. This project improved durability and consistency of the pavement without compromising performance.
Sustainable success for neighborhoods in Northern California
Multiple private communities near Sacramento and Stockton — including Rancho Murieta, Los Lagos and Brookside — recently utilized SigmaBond PG-TR binders for repaving projects. Contractors noted that SigmaBond provided comparable workability and pneumatic roller compaction to conventional binders. The half-inch dense graded overlays show no deformation to date and retain their dark black color.
Optimizing road construction in Arizona’s most populated county
Since 2014, Maricopa County has integrated SigmaBond into multiple paving projects to enhance performance and sustainability. SigmaBond PG-TR binders provide “plug and play” functionality, with contractors praising the product’s ease of use and performance.
Enhancing the performance of hot mix asphalt, sustainably.
For the paving industry, SigmaBond translates into sustainability, safety and cost savings. Pavements are better protected and stay darker and smoother longer — improving driving conditions for all. See how SigmaBond enables the use of more upcycled materials in the paving lifecycle to build a sustainable infrastructure.

Polyco makes inroads into Northern California
For years contractors in California have tried to incorporate used tire rubber into asphalt to extend the life of their roadways but with limited success. Recently, Polyco landed contracts in Northern California to assist with several paving projects powered by our proprietary Rapid Digestion Process™ (RDP), SigmaBond a revolutionary asphalt that enables hot mix contractors to …
