Taking the second phase of the reconstruction of the East Ring Road of the existing motorway in Nanning, Guangxi as an example, this paper employs ABAQUS software based on kinetic theory and the plane strain finite unit method to analyse the dynamic stress intensity factor variation law with time under dynamic load for reflection cracks. The results show that: the time course curve of dynamic stress intensity factor slows down as the thickness or modulus of asphalt paving layer increases; the time course curve slows down as the thickness or modulus of stress absorbing layer increases; the amplitude gradually becomes smaller as the vehicle speed increases; the amplitude gradually becomes larger as the axle load increases; the vibration curve gradually tends to level off as the action time continues, and the time course curve does not completely decay to zero when the load action ends.
