According to TxDOT, there are more than 79,000 miles of roadway in Texas — more than any other state! With all that pavement, the Lone Star State deserves a sustainable asphalt solution that extends the life of those roads. Since 2014, SigmaBond has helped improve the longevity of Texas pavements.

SigmaBond is an innovative asphalt modifier that enables hot mix contractors to use more upcycled materials while extending the life of pavements. Utilizing Polyco’s patented Rapid Digestion Process™ (RDP), end-of-life tires are liquified and blended to create customized asphalt formulations. With SigmaBond, we’re leveraging the performance properties inherent in those tires to construct longer-lasting roads — building a sustainable infrastructure today to ensure a brighter future tomorrow.

For Contractors

SigmaBond is easy to work with. Not only is it the only PG-TR that can be compacted with a pneumatic roller, it's compatible with standard paving equipment. Additionally, SigmaBond eliminates binder variability and manages viscosity when RAP is added to the mix.

For Terminal Operators

SigmaBond is versatile. It can be blended with any asphalt stream and offers indefinite storage stability. Additionally, SigmaBond reduces tank maintenance by eliminating tire rubber settlement.


SigmaBond is made for Texas roads. It is the only tire rubber asphalt that can improve low-temperature performance and meets all binder specifications at any tire rubber concentration. Additionally, SigmaBond enhances safety and performance, resulting in pavements that stay darker, longer.

Performance You Can Hang Your Hat On

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.
  • 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.
  • On the road near Dallas, SigmaBond lasted well beyond the city’s expected timeline, and outperformed the sections paved without SigmaBond.

SigmaBond's the Best in Texas

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. Watch this video to learn how SigmaBond enables the use of more upcycled materials in the paving lifecycle to build a sustainable infrastructure for the long term.


This Ain’t Our First Rodeo

  • The excellent performance of the first 3-years of the TRMSS in terms of no reflective cracking, no scuffing, no raveling, and no bleeding indicates that the TRMSS would very easily offer another 4-5 years of excellent performance.

Paving the Way for Sustainable Streets in Fort Worth

We recently partnered with Texas Materials (formerly TexasBit) to pave city streets in downtown Fort Worth using their multi-purpose asphaltic concrete, MAC Mix. The project resulted in a dense graded ARHM with a smooth, dark finish — but the kicker here is that the asphalt mix included up to 11% RAS and 18% PG-TR thanks …

Building Better Pavements in Texas since 2014

Attending TXAPA’s Annual Meeting this week inspired us to reflect on our impact in the state. For almost a decade, our signature asphalt modifier, SigmaBond (which is manufactured righthere in Texas), has improved the longevity of pavements with qualities that enhanceperformance across the state’s unique regions. Join us as we explore how SigmaBond buildsbetter pavements …
