With the rapid development of China’s highway transportation industry and the implementation of the “Village to Village Highway” project, a peak in highway construction has been ushered in, which also brings great business opportunities for pavement concrete.
Concrete pavement mainly bears the effects of driving loads and environmental factors, and its failure is mainly manifested as fracture.
When the sum of load fatigue stress and temperature fatigue stress exceeds the flexural strength of concrete, transverse, longitudinal, and diagonal cracks appear on the concrete surface layer, resulting in fatigue fracture damage.
Therefore, from the perspective of ensuring the bearing capacity of pavement structure, the design of concrete pavement structure is based on flexural strength.
