Based on all kinds of rapid repairing materials in home and board, the styrene butadiene latex modified early hardening sulphonaminate cement was chosen. By orthotropic design, the optimal mix proportion was obtained. Through the double shear test of different roughness, different interface agents and different ages, the best interface agent and the treatment were obtained. The multi-factor simplified formula for interface strength was given by the numerical fitting. According to test road structures and material parameters, the interface bonding feasibility of new- old concrete was analyzed by the finite software ANSYS. More stress influence factors, such as repairing thickness, new repaired concrete modulus, force site and load ect, also were studied. The results show that it is feasible by using styrene butadiene latex modified early hardening sulphonaminate cement to repair faulted joint slabs.
