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 square yard and containing 50 percent more asphalt than other rubberized slurry seals, TRMSS has revolutionized the cationic rubberized slurry seal. It delivers the durability of conventional slurry seal in addition to the rich, black color and environmental benefits of tire rubber modified emulsion.

Unlike other applications, TRMSS can be used year round and achieve the same performance — regardless of the weather. It doesn’t crack in the cold or soften in heat. Since TRMSS doesn’t soften, it does not lead to power steering marks. This is especially important for our paving partners in places like Southern California, where summer temperatures are regularly over 100 degrees! Additionally, because the rubber from the tires interacts with the asphalt, we no longer need to add latex to prevent tracking.

Even with all of these unique qualities, applying TRMSS is no different from applying other slurry seals. The same conventional slurry seal machinery is used. And because it is a sealant, which goes on top of the pavement, the benefits of TRMSS can be gained without destroying the road.

Did you know that more than 40 million tires are thrown out in California each year? TRMSS is an effective and beneficial way to divert this waste from the landfill – about 80 tires per lane mile! With a 75 percent faster production process than other slurry seals and a quick set time, TRMSS can also be applied efficiently and with fewer resources. TRMSS also has superior resistance to UV oxidation and aging, so it lasts years longer than other products. If you regularly pave in warmer climates and are seeking a sustainable, cost-effective solution, TRMSS is a great option to extend the life of your roads.

So Many Slurry Seals. What’s the Difference?

Slurry seal

Slurry seal formulations have been around for a long time. Since the 1960s, in fact! And, over time slurry seals have undergone an evolution. More sophisticated formulations have proven to be better for our environment and result in longer lasting roads. According to the International Slurry Seal Association’s “Pavement Condition Index”, [slurry seals] can extend the life of roads up to 7 years or more. However, not all slurry seals are created equal. Read on to learn more about the features that define slurry seal types.


In its most basic form, conventional slurry seals consist of a mixture of emulsified asphalt and aggregate. Unlike traditional hot mix and warm mix asphalt, conventional slurry seals can be transported and applied at ambient temperatures. Conventional slurry seals retain a consistency that is similar to chocolate milk without heat. The benefits include a cleaner process (no CO2 emissions), faster set times and flexibility with weather conditions. It can be applied in hot or cold climates, day or night. Due to its cationic nature, conventional slurry seals cure quickly, so road construction crews have to work fast!

Two Types of Rubberized Slurry Seals

Cold Blended Rubberized

There are two types of cold blended rubberized slurry seals: REAS (rubberized emulsion aggregate slurry) and RPMS (rubberized polymer modified slurry). Crumb rubber is added to the mixture cold, like an aggregate, so it cannot modify the asphalt by itself. There are some caveats with this method. Once applied, rubberized slurry seals are set through a dehydration process that is similar to paint drying. It sets much more slowly than conventional seals. And, in order to make pavements appear darker, carbon black must be added to the mixture. 

Terminal Blend

Terminal blend rubberized asphalt products are the best of both worlds. With terminal blends, rubber is introduced at the refinery or offsite, and is completely digested into the asphalt. The output is just like regular, unmodified asphalt. No special equipment or adjustments required. You can use the same conventional slurry seal machinery with terminal blends. Using highly modified asphalt is ideal because the color stays darker longer and retains a wider viscosity curve. Terminal blends can dip to lower temperatures without cracking and higher temperature without softening. This feature is especially useful in hot weather conditions, where softer slurry seals result in power steering marks.  

Now that you understand the nuances between different types of slurry seals, in our next post, we’ll take a deeper dive into the origins and benefits of terminal rubber modified slurry seal (TRMSS) and the significance of it for our partners in California.

Stay tuned for more.

Safety, Culture and Quality Drive Operational Excellence at Polyco

Here at Polyco, we believe providing a culture of safety directly impacts the quality of the products we produce. The practices and standards we follow truly set us apart. I’ll explain further how we implement these principles to drive operational excellence every day. 


Safety is of the utmost importance. I’m so proud of our record — no major safety incidents! We ensure this by doing a root cause analysis of safety issues or near misses. All of our employees are empowered to report near misses in order to prevent an actual safety incident from even happening. For example, if we don’t address a slow leak of hot oil, it could turn into a big problem and burn someone. Once a safety hazard is identified, we document it and, as a team, decide how best to address it — assigning a due date and responsible party who is accountable. 


Our next focus is fostering our culture. We ensure our team has the resources they need to do a great job and feel safe and happy doing it. When employees feel engaged, they will perform better. While each of our plants has its own personality, they all value community. Covid slowed some of our community events, but we are getting back to it. We are hosting a BBQ cook-off this month and have other events that build connections. It’s not just our plant workers; Our leadership shows up! It’s not uncommon for our President & CEO to fly in from our corporate office in Reno at least once a month to check-in on our Texas locations. And, with the magic of video conferences, we get a lot more face time which keeps the lines of communication flowing.


Quality is of utmost importance to us. Not only do we do quality testing as part of production, we also have an entire quality assurance department that continuously tests raw materials and product retains, watching for data trends so we can react before anything is an issue. Our trending models show us if there is special cause variation or drifts in our processing. This allows us to pinpoint potential issues quickly and react before anything goes out of specification — all in service of delivering a quality product. 

While we are constantly looking at ways to improve our operations, our four pillars of safety, culture, quality and customer service are always top of mind. A focus on high performance — from both our employees and products — is what drives us. And we’ll never stop.

What I enjoy doing most is working with a team to solve the most challenging problems a business faces. Seeing something that was seemingly impossible and then come out victorious is a great feeling. Luckily at Polyco we’ve got a great team and I love working with them. 

What do you like to do when you’re not at work? 

I love to learn, so I am always reading or in school. I’m working on my MBA through West Texas A&M right now. For fun, I love playing sports. Polyco has a local softball team and we play pretty much year round, so that’s a lot of fun. And I like cycling, so a lot of times I can be found cruising the roads.

Where do you call home? 

I live in Fort Worth right now, but I’ve been in Texas for five years. I’m originally from Connecticut, born and raised. I even went to college at the University of Connecticut.

What’s your favorite food?

Everything! But if I had to pick just one thing, it would be pizza. It’s just amazing. I love all toppings but the best, for me, is probably buffalo chicken.

Walking the Walk during Women’s History Month (and all year!)

As Women’s History Month winds down, we’re reminded of the importance of empowering women at our company and in our industry. This month, we celebrated this occasion by increasing our support of Women of Asphalt. As the year goes on, our commitment to empowering women will continue and we are proud to share what that looks like for Polyco.

Women of Asphalt Platinum Partner

This year, we became a Platinum Partner for the Women of Asphalt. With our contribution, we are supporting WofA’s mission to help promote, educate and empower women within the asphalt industry. 

Additionally, an opportunity presented itself recently to further support the organization at the TXAPA MAPS Conference. We auctioned our basketball hoop display to attendees earlier this month to benefit the new Texas chapter of WofA. This raffle raised $2,400 for the organization and WofA Texas was able to keep the display, so keep an eye out for it at future events.

Polyco continued to uplift WofA’s presence at World of Asphalt through sponsorship of their video and social media content. And, leading up to the event, we helped them produce a series of sponsor highlights. Stay tuned to our Linkedin for updates from the conference. If you missed any of WofA’s sponsored events at World of Asphalt, you can catch replays on Facebook.

Empowering Women at Polyco

Closer to home, we’ve opened up our blog to more diverse voices at our company. This month, our Customer Service & Logistics Leader, Kaylea LaBee, discussed her role in maintaining successful customer relationships. Next month, we’ll hear from our Director of Operations, Shelley Locker, about how she keeps our company functioning like a well-oiled machine. We’ll hear from more of our female leaders throughout the year and look forward to seeing all women of asphalt excel.

Customer Service Drives Success at Polyco

In an industry that is hyper-focused on the product, maintaining solid customer relationships is vital to our success. Meeting and exceeding the expectations of every customer at every location is extremely important to our business. It takes all of us — from our sales and technical teams to operations — to ensure our material is delivered on time and in spec. How do we do it? It starts with trust.

Being transparent with our customers helps foster that accountability. When a customer service email is sent to Polyco, it not only goes to my department but also logistics, operations and the spec team. There’s a whole team to back me up to ensure our customers are taken care of. Once an order is placed, I follow up with our internal teams before confirming the order with our customer. Whether customers need a rush order or are stockpiling a month out, it’s our responsibility to be mindful of their unique ordering processes. 

We are flexible and amenable to meet our customers’ needs, so there aren’t any surprises when we send a BOL or invoice. Being small (but mighty) has its advantages. We can more easily modify hours and personnel availability to accommodate receipt, offload and load times.

We also have great relationships with our carriers — some of them have worked with us since the company’s inception. Once we get a carrier nailed down, we follow up with our customer orders to confirm logistics. Weekly check-ins are vital to ensure orders stay on track. Once orders are shipped out, we stay in open communication with our carriers daily in an effort to avoid delays. The entire process is monitored all the way through delivery and invoicing.

It’s an honor to work alongside a great team to deliver amazing customer service. I look forward to helping Polyco continue to foster our customer relationships as we move the needle on sustainable performance asphalt products.

The Power of Partnerships at Polyco

Here at Polyco, we consider everyone we align ourselves with a partner, including the organizations we support. In the past year, we’re proud to have expanded our affiliations to include organizations that are working to improve the asphalt industry for all. We’re excited to share how these relationships will take shape throughout the year.

Women of Asphalt

In 2022, we’re proud to support the Women of Asphalt as one of their Platinum Partners. With our contribution, we are supporting WofA’s mission to help promote, educate and empower women within the asphalt industry. Additionally, we’re excited to uplift WofA’s presence at next month’s World of Asphalt through sponsorship of their video and social media content. If you’re planning to attend the conference, we hope to see you there! If you can’t make it, stay tuned to our Linkedin for updates from the event.

Asphalt Institute Foundation 

I am proud to be the Vice Chair of the Asphalt Institute Foundation and Chair of its Education Committee, which funds asphalt research, internships and scholarships through a variety of programs. In addition to my tenure, Polyco supports AIF’s distribution of educational materials to universities across the U.S. and Canada. In fact, this week we will deliver modules and support manuals to engineering students at Tarleton State University in Stephenville, Texas. Engaging students with such close proximity to our Texas locations will hopefully spark an interest in the industry for soon-to-be graduates.

Asphalt Institute and Asphalt Pavement Alliance

Polyco is also deeply connected to AIF’s parent organization, the Asphalt Institute. Our Chief Operating Officer, Daniel DeJarnette, is part of AI’s Roofing Technical Committee — which is an important part of our business. I had the honor of serving one term as AI’s Vice President and continue my service to the organization as one of AI’s representatives at the Asphalt Pavement Alliance. Because APA is a coalition of the Asphalt Institute, National Asphalt Pavement Association and State Asphalt Pavement Associations, it’s a great way to keep a pulse on the most pressing needs of the industry. 

National and State Asphalt Pavement Associations

As our footprint grows on the paving side of the asphalt industry, we’re proud to be members of NAPA, TXAPA, OAPA in Oklahoma and CalAPA. Aligning ourselves with these organizations in key markets helps to advance the science and use of asphalt on our roads. We look forward to engaging more with industry insiders throughout the year at members-only meetings.

I can’t wait to see what lies ahead for Polyco and look forward to strengthening our partnerships. It’s going to be a great year!

Learning from the Past to Succeed in the Future

As we settle into the new year, I’m reminded of the challenges the asphalt industry faced in 2021 and how we’ve worked (and continue to work) to rise above them. From pandemic-related shutdowns and extreme weather in several of our markets to workforce retention and supply chain setbacks, we’ve watched our customers and partners pivot on a dime to adapt. And, we’ve adapted along with them. Last year gave us some valuable lessons that we will continue to carry with us as we look ahead. 

Green Isn’t Going Away

Being sustainable is no longer a “nice to have.” More and more states are adopting sustainable practices, which has impacted both our roofing and paving customers. Many refineries have converted to renewable sources of energy in order to reduce their carbon output. And, on the paving side, states and municipalities are increasingly enthusiastic about adding more recycled materials (including recycled asphalt shingles) to their asphalt mix as a way to stretch their budgets. Additionally, as supply chain woes continue to impact raw materials sourcing, organizations throughout the industry are looking for more ways to draw down their reliance on imported resources.

Longer-lasting is the Way to Go

Extending the life cycle of pavements and shingles makes sense from both financial and sustainability standpoints. The longer they last, the longer before they need to be replaced, reducing waste. As roofing manufacturers are pushed to offer near-lifetime guarantees, they will inevitably look for ways that make them more resilient. In road construction, the industry has experimented with several ways to extend a pavement’s life — from additives and higher-quality mix formulations to the practice of “Perpetual Pavements.” The Asphalt Pavement Association has written at length about “Perpetual Pavements” and more local agencies have latched on to the concept. Perpetual pavements can resist structural fatigue distress for at least 50 years, which is significantly longer than traditional asphalt.

Polyco is Positioned to Perform

As the asphalt industry continues to adapt to meet the needs of the market, Polyco is poised to meet customers where they need to be. We understand that everyone’s needs are different. This is why everyone here — from our lab personnel to our operations team — pride themselves on customizing and delivering asphalt formulations that exceed customer expectations. Our Sigmabond product is an example of this innovative mindset. Sigmabond is a rubber modified asphalt that enhances the performance of asphalt products using end-of-life tires. In addition to our products and practices, the most important element we bring to the table is our people. Each and every one of us values a job well done and ensures that we take care of each other so that we can take care of our customers. 

With our commitment to sustainability and innovation firmly in place, I’m looking forward to seeing what exciting developments lie ahead of us this year and beyond.
