Abstract

High Friction Surface Treatment (HFST) has emerged as an advanced road surface maintenance material due to its excellent performance and ease of application. This study investigates the durability of High Friction Surface (HFS) materials prepared with different epoxy resin binders and explores their skid resistance based on differential polishing principles. Accelerated wear tests were conducted on HFS specimens made with three different epoxy binders to examine aggregate loss over prolonged polishing. It was observed that the HFS aggregates prepared with modified epoxy resin binders exhibited the lowest aggregate loss of 5.84 % and 10.76 %, while those prepared with unmodified epoxy resin binders showed significantly higher aggregate loss compared to the experimental group. This indicates that the modified epoxy binder system has effectively enhanced its toughness and adhesive properties. Furthermore, weather resistance was evaluated through freeze-thaw cycle tests and UV aging tests, revealing that HFS prepared with modified epoxy resin binders exhibited the smallest reduction of 14.41 % in bonding performance, whereas HFS prepared with unmodified binders nearly lost their service functionality. Lastly, dynamic friction coefficient tests were performed on the post-polishing samples to assess their skid resistance durability. The results indicated that HFS made with blended aggregates and modified epoxy resin binders is more cost-effective and provides better skid resistance. Therefore, HFS prepared with modified epoxy resins demonstrates superior durability.
