Abstract

Although high friction surface treatment (HFST) has been widely installed in recent years, validation efforts considering various materials, installation ages, environmental conditions, and traffic levels are missing primarily due to lacking of high-speed data collection instruments. Utilizing laser imaging technology and fixed-slip friction tester, this study collects comprehensive pavement surface data at 21 HFST sites in 11 states at highway speeds. Measurements on HFST and untreated pavements are compared to determine the effectiveness of HFST. Multivariate analyses are conducted to investigate the impacts of factors on HFST friction. Average temperature and installation age are identified as the significant factors. The HFST sites constructed using calcined bauxite aggregates exhibit better friction performance than those using flints. Subsequently, friction models are developed to aid highway agencies in managing HFST.
