HIGH FRICTION ROADS
LEARN ABOUT EACH SEAHC PROJECT:
Demonstration projects have been installed in eight states to date to determine the effect of HFS on reducing crash rates on horizontal curves. The states participating in this effort identified specific horizontal curves with high crash rates that could benefit from the installation of HFS, and installations were completed in Summer 2009 through Summer 2011.
Projects shown in the map include all projects tested under the SEAHC Program. See specific project pages for installation and testing information under the SEAHC Program: Colorado, Kansas, Montana, North Carolina.
For each SEAHC HFS installation, friction and texture testing were conducted on the existing pavement surface just before application of the HFS material, and on the finished surface immediately following HFS application.
Tests were conducted in the right wheelpath and center of the lane at 2-4 locations per site, depending on the section length. The same tests will be conducted again at each site approximately one year after the HFS was installed.
The following tests were conducted at each site:
