Analysis and control of early cracks of airport concrete pavement

Most of the newly-built pavements of airports in China are rigid pavements made of cement concrete, which have good durability, stability and high strength. However, the early cracks in the airport pavement construction may endanger flight safety. If it is not dealt with in time, the life of the pavement will be shortened and even cause flight safety accidents under the cumulative effect of aircraft impact loads for a long time and the influence of the natural environment. This paper analyzes the causes of early cracks in the cement concrete pavement of the airport and proposes a series of preventive measures to control them in combination with the expansion project of the deicing floor of Tianjin Airport.
