Cost-Benefit Analysis of Preventive Maintenance Treatments for Semi-rigid Base Asphalt Pavement in Jiangsu, China: A Pilot Study

The Jiangsu provincial highway network consists of 4121 km of asphalt pavement which includes a semi-rigid base at the end of 2012. Currently, a maintenance decision support system which includes detection, analysis, decision-making, implementation, and evaluation is being established and updated. In this research, a preliminary study of preventive maintenance treatment dealing with the implementation and evaluation stages, focused on cost-effectiveness assessment and function validity by comparing various rut preventive maintenance treatments included microsurfacing, ultra-thin overlay, hot in-place recycling and thin hot mix overlay, etc. The Jiangsu provincial highway network status and major distress were studied based on the statistical analysis of the performance data and maintenance history which was collected from the Pavement Management System (PMS). The determination method of Extended Service Life (ESL) index of the different preventive maintenance treatments was recommended according to the rut depth used as the control performance indicator. Combined with the ESL value, the Benefit-Cost Ratio (BCR) value using Life Cycle Cost Analysis (LCCA) method was calculated with different rut preventive maintenance treatments, and their effectiveness was compared. The results indicated microsurfacing has the highest cost-effectiveness, ultra-thin overlay and HIR have similar cost-effectiveness level, while thin hot mix overlay has the lowest BCR value compared with other treatments. Furthermore, in terms of the different rut depths, preservation treatments are recommended in Jiangsu Province. The findings will support for the PMS updating for maximize both project and network level benefits, combined the preventive maintenance management system in the near future.
