| 摘要： | Example pavement performance for different maintenance and rehabilitation (M&R) strategies is presented. The effect of the different performances on pavement life-cycle costing is also analyzed. A pavement network of 1.5 million sq yd was used for illustration. Three M&R strategies were applied to the pavement sections in the network: structurally designed rehabilitation, thin overlay (1 to 2 in.), and thick overlay (3 to 4 in. with or without fabric). Three family curves were developed, one for each M&R strategy, from available data bases. These family deterioration curves were each assigned to the pavement network and a work plan was developed. The results illustrate the economic effect of asphalt overlays compared with structurally designed rehabilitation. The family curve and work planning techniques are procedures incorporated in the MicroPAVER pavement management system. These techniques are also discussed. |
