Prior to PCC placement, the surface of asphalt-treated base may be sprayed with water, water-lime solution, or concrete curing compound to reduce the surface temperature, which may reach 140 °F or higher. Alternatively, night-time paving maybe considered. Control of surface grade is also important for asphalt-treated base.

 · At the same temperature, conventional asphalt concrete will have stiffness values in the range 5.5 to 7×106kPa (800,000 to 1,000,000 psi). If the ATPB is saturated and the material is sensitive to water, the stiffness may be reduced to the value of about 5×105(75,000 psi), about one-half that in the dry state. While the stiffness values
