Significant development of the highway network will occur in China in the next 10 years. The characteristics of the change are embodied in a relatively large investment in new construction and upgrading of the existing highway network. Consequently, it is important to manage the available funds, resources, and technology in the most efficient and cost-effective way. Although the pavement management technology was developed in North America, there is a tremendous benefit to be gained by applying it in developing countries. As a result, some developing countries have established pavement management systems (PMSs) to better manage their road infrastructure assets. PMSs in China have rapidly progressed from a concept to a broadly accepted practice over the past few years. A methodology is established for the implementation of a special PMS in the developing areas of China. The emphasis is on establishing road investment priorities that are adjustable and suitable to developing countries, which includes determination of the present status of the network, developing needs, and priority programs that consider the future serviceability of the network. The system was applied to an actual sample network of the Southeast Economic Developing Region of Qinghai, China, where a large amount of new construction will be undertaken while rehabilitation and maintenance of the existing pavement will be carried out at the same time. |
