Abstract: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.
