In the bridge deck system structure of in-service highway bridges, the bridge deck pavement has premature cracks, pits and other diseases, which seriously affects the normal use of the bridge deck. Comprehensively analyze the factors affecting the deterioration of the bridge deck system, put forward the service performance attenuation model of the bridge deck system under the influence of heavy traffic and large temperature difference environment, select the actual project to verify the applicability of the attenuation function, finally analyze the variation law of the attenuation function, and determine that the best preventive maintenance time of the bridge deck system under normal load is the third year, The best preventive maintenance time of bridge deck system under heavy load is the second year, which provides a theoretical basis for guiding engineering practice.
