Durable Aggregates for Bridge Deck Overlays and Other High Friction Surfacing
The driving conditions of any preexisting roadway, bridge deck, exit/entrance ramp, or curve can be quickly and easily improved with Kafka Granite’s high-friction surfacing aggregates. The high-friction surfacing application greatly increases traction year round and helps trap road salt during the winter, making the deicing process more efficient and effective. Kafka Granite’s extremely hard high-friction surfacing aggregates easily endure the freeze/thaw cycle and other rigorous conditions. In addition, our various colors can be utilized for drivers to easily distinguish the road from bike paths, crosswalks, and other pedestrian walkways.
Kafka Granite’s high-friction surfacing aggregates can be manufactured to meet Department of Transportation specifications, which is generally 3/16” x 1/16″ or 1/8″ x 18 mesh for vehicular applications, therefore creating a total additional thickness of 3/8” to your preexisting hardscape roadway. After the preexisting surface is thoroughly cleaned, a two-part epoxy is evenly spread and the aggregate is dispersed. After the aggregate has set, the excess is swept away and can be reused.

Our decomposed granite aggregate and crushed stone come in over 50 colors, leaving you with essentially endless options for your project. Many of our options are locally sourced or are made from recycled materials, which could help garner points toward LEED certification. If you want to differentiate high-friction surfaces from surrounding portions of roadway or walkway, we have your everlasting solution in the form of a contrasting color.
What is high-friction surfacing?
High-friction surfacing is way to make a roadway safer by providing more traction and grip between your vehicle and the surface of the street. This solution to slick or dangerous bridge decks, overpasses, exit/entrance ramps, or curves uses a layer of two-part epoxy topped with a hard fractured aggregate.. When high-friction surfacing is employed, traction is substantially improved, making conditions safer for drivers.
High-friction surfacing can be applied in a short amount of time if the preexisting surface is in good condition. Repairs will need to be made to roadways that are badly deteriorated or in severe need of help. This life-saving treatment can be applied anywhere, however it is most effective when used on bridge decks, exit/entrance ramps and curves as these are the most slippery and accident-prone stretches of road.
Why would I want to use high-friction surfacing?
An incredible number of highway fatalities occur due to deteriorated surfaces. Roughly 40,000 people die every year in highway accidents, costing U.S. motorists over $164 million annually. Roughly 25 percent of all crashes occur on wet pavement and nearly three times as many crashes occur along horizontal curves than on other highway segments; these are the parts of roadways which could benefit the most from high-friction surfacing with our hard aggregates.
Not only does high-friction surfacing drastically improve the roadway’s traction, but it also provides a very durable surface that can better withstand the demands of day-to-day motorist traffic and the severe freeze/thaw cycles.
