During the early stages of pouring and forming cement concrete pavement panels at airports,if there are crack de-fects inside the concrete structure,under the action of deformation,the micro cracks will gradually expand into visible cracks and even develop into pavement diseases.To control the continuous expansion of early micro cracks,this article analyzes the causes of cracking and corresponding control measures of pavement panels from three as-pects including material of cement concrete pavement,pavement panel design and pavement construction,by com-bining with a certain airport pavement project.This study can provide a reference for similar projects required to control early micro cracks in concrete.
