摘要： PROBLEM TO BE SOLVED: To provide a judging method for a traffic opening period, which can make an early decision on weather to open traffic or not, upon executing pavement or repair work using porous concrete on existing concrete pavement slabs or floor slabs. SOLUTION: The decision on weather to open traffic or not is made after executing the pavement or repair work of smearing a bond on the surface of the existing concrete pavement slabs or floor slabs and driving the porous concrete onto the surface. In making the decision, a sample is made by smearing the bond on the surface of a core extracted from the existing concrete pavement slabs or floor slabs, or on the surface of a concrete simulative body thereof, driving the porous concrete onto the surface, and curing and hardening the core or the simulative body with the porous concrete. Then, the shear strength of the sample and a target value (shear strength) for traffic opening, which is driven from a separately created linear regressive equation on bond strength and shear strength, are compared to make the decision.
