Continuous, synchronous high performance chip seal.

RoadArmor^® high performance chip seal is a single pass surface treatment for pavement preservation on low-to-high volume asphalt roads. A Stylink^® polymer modified asphalt emulsion and a durable single-sized aggregate are both continuously applied by a single machine.

The Pavement Preservation Lead States have found that a sound pavement preservation program costs three to 10 times less than rehabilitation and results in a higher overall quality road system. A Transportation Research Board study concluded that chip seals are one of the most cost-effective pavement preservation tools. However, some agencies have discontinued the use of such surface treatments because they have not always given the expected performance. Problems can occur because of the complexity of controlling the multitude of variables (including materials, equipment, site selection, surface preparation, weather, traffic control, operator training). Only a few agencies use chip seals on high-volume roads because of prolonged user delays and unpredictable performance.

RoadArmor high performance chip seal is a process that uses superior materials and combines the construction processes, taking out many of the variables and yielding a much more reliable, yet still cost-effective surface treatment.
