Abstract
The main problems of repair materials for concrete pavement are big shrinkage and weak bond etc. The rapid repair material discussed in this paper is concrete with compound early-strength admixture. Its compressive strength and flexural strength (1d) is up to 23.1MPa and 3.74MPa respectively, which meets open to traffic demand in one day. Repair materials mixed with alkali-proof glass fiber or polypropylene fiber mesh were studied. Flexural strength and interfacial bond strength increased, shrinkage value reduced when fiber was blended. The results indicate that there is a strong linear correlation between splitting strength of repair material and bond strength.
