This paper analyses the costs, effectiveness, and cost-effectiveness of three standard rehabilitation treatments of rigid pavements using historical data from the state of Indiana. Treatments investigated are Hot Mix Asphalt (HMA) Overlay, Patching, and Portland Cement Concrete (PCC) Overlay. Performance criteria used are the sudden decrease in surface roughness after treatment, treatment service life, and increase in average pavement condition over the service life. Cost-effectiveness is the ratio of treatment effectiveness to treatment cost. Results suggest that Patching and PCC Overlay treatments are the most effective on the basis of short term and long term effectiveness, respectively. The results also show that at relatively small levels of traffic loading, a change in climatic severity has greater influence on treatment effectiveness than that at higher levels of traffic loading. On the basis of cost-effectiveness, the results suggest that PCC Patching appears to be the best treatment.
