Abstract:

Polymer overlays consist of polymer resins and aggregates and are used on bridge decks to extend service life by providing waterproofing and chloride penetration resistance and restoring surface friction. High friction surface treatments (HFSTs) are a specific type of polymer overlay intended to provide long-term skid resistance by using aggregates with increased abrasion resistance. This study investigates the performance of HFSTs in Montana to address Montana Department of Transportation concerns regarding their durability and cost effectiveness. The objective of this research was to assess the factors that influence the long-term friction resistance and durability of polymer overlays, particularly HFSTs, in Montana. The study included a literature review of recent studies on thin polymer overlays and bridge HFSTs, a survey of the experiences of select transportation agencies across North America with polymer overlays, a field investigation in which the condition of HFSTs on select bridge decks across Montana was monitored over a period of three years, and laboratory work to supplement the field investigation and its findings. The study found that the HFSTs investigated are generally of good quality, had adequate installation practices, and have provided at least 5 years of satisfactory performance.
