WHY MODERN ROADS FAIL FASTER

Modern oil refineries have gotten extremely efficient at extracting valuable compounds from crude oil. While that’s great for producing gasoline, it means the maltenes—the flexible compounds that keep asphalt soft and pliable—are being stripped out before they reach your roads. 

THE RESULT? Your new pavement starts with up to 50% less maltene content than it needs. So you end up building roads with half the required materials—it looks fine initially, but it’s compromised from day one. Roads that should last 20-25 years are showing serious problems after just 5-10 years, and your maintenance budget can’t keep up. 

We can’t change how modern asphalt is manufactured, but our Maltene Replacement Technology (MRT) addresses this fundamental chemical imbalance by restoring what’s missing instead of just patching the symptoms.

How MRT Works

THE SCIENCE BEHIND OUR SOLUTIONS

We use maltene-based rejuvenation technology that addresses the root cause of asphalt deterioration, not just the symptoms. When asphalt ages, it loses essential maltene compounds that keep it flexible and durable. Our products penetrate deep into the pavement to restore these critical compounds, creating measurable improvements in asphalt flexibility and durability. 

Independent laboratory testing confirms our treatments can reduce asphalt viscosity by 56-63% after just three months, with benefits lasting for years. Unlike surface treatments that only change appearance, our maltene-based rejuvenators actually extend pavement life by 5-10 years per application, saving you significant maintenance costs.

A comprehensive pavement condition inspection of your road inventory can reveal which roads need invasive maintenance and which are perfect for preservation. Precise application of CAM treatments based on condition assessments ensures optimal use of maintenance funds and maximizes pavement lifecycle performance.

Chart Summary: This chart provides a picture of cost savings through proactive pavement preservation. On the vertical axis we have the Pavement Condition Index ratings also known as PCI ratings. On the horizontal axis, we have the road life in 5 year increments. The chart displays what the natural deterioration curve for asphalt pavement looks like. We see that there is a 40% drop in the quality of an asphalt road during the 10 years of its life. However, we can mitigate this quality drop by spending $1-$2 per square yard while the pavement is in its initial life stage and save anywhere from $10-$50 per square yard in maintenance costs during the first 15 years of the pavement’s lifecycle.
