| Abstract: | This paper discusses the preparation, properties, determinations of compressive strength, flexural strength, modulus of elasticity and interfacial adhesion strength of quick repair materials for bridge concrete surfacing layer and concrete pavement. Also discussed are the determinations of long term performance and durability characteristics of these materials, such as resistance to low temperature, contractibility and resistances to abrasion and erosion. Based on the discussions, the mechanism of quick-stiffening and early-strengthening is explored with recommendations of construction techniques for practice. |
