Kwik Bond Polymers(TradeName) High Friction Surface Treatment.

摘要

High friction surface treatment (HFST) was applied to two on-ramps in the Seattle urban area to improve friction resistance. The ramps were high accident locations. The system applied was polyester resin binder and calcined bauxite aggregate. Testing of the completed HFST resulted in average friction numbers (FN40R) ranging from 75 to 86 with no individual value below 72. An evaluation period of five years is planned to monitor the performance of the HFST. At the end of the five-year period, a final report will be written which summarizes the friction and performance characteristics of the application, its effectiveness at reducing collisions, its cost effectiveness and recommendations on the future use of the high friction surface treatments.
