Drying Shrinkage Model of Airfield Pavement Concrete in Windy, Dry, and Torrid Regions

In windy, dry and torrid regions, early-age cracking severely threatens airfield pavement durability. In the light of the analysis of drying shrinkage mechanism of pavement concrete, a model for drying shrinkage deformation of early-age pavement concrete was designed. Besides, the model was validated with experimental data. The result of experiment shows: as to the pavement concrete of w/c=0.35, drying shrinkage strain can approximately reach 1.8 mm/m during 20 days after casting, and the shrinkage strain rate is relatively high in early 7 days; drying shrinkage strain of pavement concrete is an exponential function of time.
