Polymer concretes are finding increasing use as bridge deck overlays. They are impermeable, skid resistant, lightweight and develop strong bonds to well prepared bridge decks. The properties of the polymeric binders and aggregates used to form the polymer concrete are important to the success of the polymer concrete overlays. The binders should be strong and yet flexible and low modulus and the aggregates should behard and resistant to polishing and fracturing. Case histories where such overlays were used in major projects are described in detail together with the methods and equipment used in their application.
