Bond Behavior of Nano-Enhanced Polymer Concrete for Bridge Deck Overlays

Polymer concrete overlays are light weight, wear resistant, skid resistant and waterproofing characteristics make them an intelligent and durable decision for new construction, maintenance, rehabilitation and preservation of bridges. A polymer concrete overlay also minimizes traffic disruption. It’s generally applied at a total thickness of only one-half to three-quarter inch. Their rapid cure (open to traffic within 3 hours) characteristic is highly suitable for accelerated bridge construction applications. In some cases, workers can place the overlay at night then open it to traffic the next day. Moreover, these overlays are corrosion resistant, providing a barrier between the dissimilar materials to minimize galvanic corrosion, saving the expense of applying additional corrosion-resistant primers to the steel reinforcement; have very good cracking resistance and have superior durability [1]. When bridge deck overlays are considered, a strong bond to the existing concrete surface and/or reinforcement is required. The properties discussed above make polymer-based materials a favorable material for bridge deck overlays [2] but improving the bond strength of polymer concrete is heavily unexplored and can bring significant benefit in accelerated bridge construction. Polymer-based overlays show no delamination with the substrate concrete beams after 2 million cycles of fatigue loading [3]. It is important for the bonded joint to be able to sustain all expected in-service loads and environmental conditions, which can vary considerably.
