Short-Term Cost-Effectiveness Evaluation of Maintenance Treatments for Asphalt Pavement in Jiangsu, China

Abstract

The short-term cost-effectiveness of maintenance treatments in asphalt pavement were evaluated based on the pavement historical maintenance records and pavement performance data from the pavement management system (PMS) in Jiangsu province, China. This paper took a deep investigation into the short-term cost-effectiveness and created a short-term cost-effectiveness analyses scheme. Applying the principles of engineering economy, this study analyzed the performance vary quantity, performance vary slope and performance vary rate of both pretreatment and posttreatment pavement performance trends and selected cost-effectiveness ratio as the short-term treatment cost-effectiveness evaluation index. Some statistical data analysis methods were used to eliminate the abnormality data, then formed a short-term cost-effectiveness scheme. Finally the short-term cost-effectiveness of four kinds of maintenance treatments (thin ECA overlay, mill and fill, micro surfacing and hot-in-place recycling) were evaluated and verify the feasibility of the scheme. The analyses indicates that the effectiveness of maintenance treatments on moderate-traffic and AK pavement structure are better than on low-traffic and SMA asphalt pavements, respectively. Analyses results that thin ECA overlay has more short-term cost-effective than other three treatments.
