Initially high humidity at concrete surface is continued for a long time by raising curing effectiveness, and smaller difference in the humidity between top and bottom of the slab is maintained as the result. Shear stress can be minimized if the humidities at top and bottom of the slab are maintained at almost same level by raising the curing effectiveness because the humidity variation with the slab depth causes the shear stress. If delamination is not formed in the slab by maintaining the shear stress below the shear strength, spalling due to loads and turning forces of vehicle wheels applied to the delaminated pieces will not develop. A mechanistic approach to minimize the delamination which develops at the slab depth of the greatest humidity change and consequently the spalling by controlling moisture evaporation from surface of the newly placed concrete is explained in this paper. In addition, a tool calculating the shear stress in the slab due to the moisture evaporation was developed and validated by using a series of laboratory test data.
