Abstract: The prevention of reflective cracking in pavements has always been an area of concern when designing for asphalt concrete overlays. One way of delaying or arresting reflective cracking in asphalt overlays, which are to be constructed on existing cracked pavement structures is to use reinforcing systems. The goal of the research presented here was to investigate the effect of coating on fiberglass road reinforcing systems' performance. The materials tested included: greige and coated glass fiber roving and respectively fabrics with the same construction and/or strength, and existing coated and non-coated glass fiber composite road reinforcement products. The performance was assessed based on mechanical test results and optical microscopy images of the grid cross-sections. The experimental results suggest that coatings can optimise the performance of glass fiber reinforcement products, and thus they are critical for fiberglass products. Using specially designed coatings and improved coating processes can optimise the overall performance of the glass fiber reinforcement products. This study is part of an ongoing research project developed by Saint-Gobain Technical Fabrics and aimed to continuously improve existing road reinforcing products.
