TPO AD - Thin Polymer Overlay

A High Molecular Weight Methacrylate (HMWM) first layer saturates the substrate concrete permanently repairing cracks and restores flexural continuity within the bridge deck while promoting adhesion of the composite TPO AD system. The hybrid polyester copolymer binder resin second layer further protects the bridge deck and secures a durable, high friction calcined-bauxite broadcast aggregate.
