| 摘要： | Full-depth reclamation (FDR) can offer an economical and rapid strategy for pavement renewal. With pavement damage coinciding with energy sector development, departments of transportation need rapid and economical methods to strengthen and renew these impacted pavements. This project focused on implementing FDR for pavements in the energy sector. A systematic approach for evaluating pavement sections was developed, and training workshops were conducted. Nominated pavement projects were analyzed to determine their candidacy for FDR, and mixture design options were developed for the available materials with particular focus on asphalt-based stabilization. A total of 10 pavement projects were constructed and monitored during this implementation effort, representing a spectrum of asphalt-based and calcium-based FDR along with two mill and inlay projects for comparison. Field performance of constructed sections shows FDR with asphalt-based stabilization is a viable structural option to other alternatives such as mill and inlay or cement treatment with base overlay. While not every distressed pavement is a candidate for FDR, successful FDR projects can renew the pavement at a cost typically at least 50 percent cheaper than other alternatives. FDR can also offer significant time benefits in terms of production rate and minimized disruption to traffic. With the substantial benefits of successful FDR demonstrated in this implementation effort, updated construction specifications were developed. |
