Abstract
With the aggravation of high grade highway asphalt pavement destructions, it becomes particularly important to maintain pavement performance and enhance road economic efficiency. The asphalt pavement preventive maintenance technology is an effective technique to extend pavement services and maintain pavement performance. In this paper, we combine the decay model of pavement performance with assets value evaluation idea and establish an analytical method about preventive maintenance technology based on assets evaluation. An example of hot asphalt overlay is also presented, it is found that preventive maintenance techniques can reduce the attenuation of road infrastructure assets value and maintain pavement performance efficiently.
