The lack of information on reliable life-extending benefit for pavement preservation treatments led the National Center for Asphalt Technology (NCAT) to conduct a preservation study applying preservation treatments on a low-volume county road in Auburn, Alabama, which began in 2012. The primary objective of the study is to develop performance models for preservation treatments to be used in pavement management systems. Performance measures including rutting, cracking, and roughness are collected on a regular basis to the present date. Among all the collected measures, only cracking shows an upward trend and therefore was used in this study as the performance index for the analysis. The present study aims to implement a semi-parametric survival analysis technique to assess the effectiveness of treatments used, and to investigate associated risk factors. The study confirms that preservation strategies significantly decrease the risk of failure when compared with a “do-nothing” scenario. It was found that initial condition, treatment family, recycled material usage, and crack sealing application have a significant impact on future deterioration. It is also concluded that survival analysis techniques are useful tools in aiding decision makers in the selection of proper treatment choices.

Low Volume

The main issues that have been addressed in the Costa Rican government’s policy for low-volume rural roads are discussed. As in most developing countries, providing good roads to support the growing demand for agricultural and tourism activities has been a great challenge, especially in times of important budget limitations. The Costa Rican experience is shared in the hope that it can prove useful in other countries, because its impact has not been limited to just providing better roads; it is also helping to motivate widespread citizen participation and to improve technical and organizational capabilities of the local governments. Because the majority of the rural roads are managed by local governments, whose administrative and technical capacity has been limited in the past, the central government, through the Ministry of Public Works and Transportation, has developed a comprehensive policy based on simple technology transfer programs and regulations for these organizations, while at the same time inducing a method of investment planning that requires organized citizen participation. The program, called Participative Road Conservation, has become the center of the government’s policy. Some of the highlights of the program are presented. The strategy of the program has been to give straightforward guidelines in organizational issues of road maintenance at the local government level (including the local road committees), basic technical standards to be followed, and planning methodologies. One of the fundamental principles of the program is the sharing of responsibilities for adequate road maintenance, including financial contributions, among the communities, the local government, and the central government. This policy for sustainable rural roads is making a change in the road maintenance culture of the country. It has required educational programs concerning the importance of roads, the correct way to build and maintain them, adequate control of the work, and so forth. Once the community is involved in planning and rehabilitating a road, it is more likely that the road will not be allowed to deteriorate again. Even children are involved in a program of school patrols. The financial reforms that have been made in Costa Rica to attend to the needs of the national and municipal road systems are also addressed.

Nonhierarchical Clustering

The management of low-volume rural roads in developing countries presents a range of challenges to road designers and managers. Rural roads comprise over 85 percent of the road network in India. The present study aims at development of deterioration models for the optimum maintenance management of the rural roads under a rural road programme namely Pradhan Mantri Gram Sadak Yojana (PMGSY) in India. Visual condition survey along the selected low-volume rural roads considers parameters like condition of shoulders, drainage features, cross-drainage structures, and camber, and pavement distresses, namely, potholes, crack area, and edge break, are collected for a period of three years. The deterioration models have a significant role in the pavement maintenance management system. However, the performance of a pavement depends on several factors. Cluster analysis can be used to group the pavement sections so that the performance of pavements in different clusters can be studied. Nonhierarchical clustering technique of k-means clustering was considered. Separate deterioration models have been developed for each of the clusters. A comparison of the models developed with and without clustered sections reveals that the clustering of pavement sections are preferred for the efficient rural road maintenance management.
