Evaluation of High Friction Surface Treatment Binders

This project contains a series of field related activities. One type of aggregate topping (bauxite) will be applied to at least four different types of binder at up to 30 sites to generate high friction surface treatment. Selection of sites and construction of surface treatment at these sites is not within the scope of work defined for Penn State involvement with this project. Penn State will visit the sites for general evaluation before application, observation and documentation of findings from placement and construction, and will conduct a follow-up visit after 30 days to evaluate initial performance. The overall goal of the project is to evaluate the construction, implementation, and initial performance of high friction surface treatment (HFST) at high-crash sites using at least 4 different binder materials. The findings of this project will be used by the Pennsylvania Department of Transportation (PennDOT) to better determine which binder materials and construction practices successfully work for HFST use and application.
