Abstract To solve the fatigue cracking problem in orthotropic steel decks (OSD) and to prevent the early damage of bridge pavements resulting from the low stiffness of the bridge deck system, epoxy-resin-perfused concrete (RPC) pavements were developed for improving the modulus and road performance of paving materials. The mechanical and road performance of RPC and the bonding performance of the waterproofing adhesive layer were studied via laboratory experiments. The mechanical property of RPC pavements and their protective function on OSD were analyzed by using a finite element model. Composite beam fatigue life and acceleration loading tests were performed on a scaled model to verify the performance of these pavements. Results show that RPC has excellent high-and low-temperature stability and water stability that can meet the requirements and has a relatively long fatigue life. The bonding strength of RPC pavements and steel plate is better than that of epoxy asphalt concrete and Gussasphalt concrete pavements. RPC pavements have a relatively low tensile stress on the surface and a relatively high shear stress below the surface, but these stresses are far lower than the material strength. When paved with RPC, the stress in the fatigue details of OSD is reduced by more than 20%. The maximum relative deflection between ribs, the minimum curvature radius, and the relative deflection to span ratio of RPC are also favorable, thereby providing additional protection for the bridge deck system. The fatigue life tested with a five-point bending composite beam is more than 1 million times, which meets the requirements. In the acceleration loading test, RPC pavements do not show any rut, whereas the OSD shows no cracking when loaded for 12 thousands times. The engineering application results demonstrate the feasibility of using RPC pavements and show that these pavements and OSD endure no damage.
