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.
