Expressway play an important role in the construction of arterial road networks. On the other hand, users have complained about the road surface condition, and effective maintenance of the road surface is necessary to maintain a high level of service that allows vehicles to travel at high speeds without stress. In this study, for the purpose of preventive maintenance of road surfaces, the distribution status and causes of complaints received from expressway users were analyzed based on geographical analysis after classifying the type of damage. In addition, the road surface profile analysis focusing on individual complaint points suggested that the deterioration of road surface condition (occurrence of road surface damage leading to complaints) can be confirmed by looking at the increase in the excellence level of road surface wavelength in the 4-8 m wavelength range.
