| 摘要： | The Arizona Department of Transportation (ADOT) has been using cold in-place recycling (CIR) as a rehabilitation strategy for over two decades. Several highway pavements throughout the State have been rehabilitated using CIR, typically in conjunction with an asphalt overlay or a double application of seal coat. As with any other aspect of design and construction method, practices used to assess the feasibility of CIR on a given project, the CIR construction process, and the materials used to produce CIR materials have evolved over time. The primary objective of this investigation was to evaluate and document the performance of selected CIR projects in Arizona. To satisfy this objective, detailed design, construction, performance, and traffic data on 17 CIR projects were compiled and summarized. In-depth profiles of each project, including historical trends of key distresses (cracking, rutting, flushing), ride quality, and maintenance costs, were developed and are presented in this report. The 17 CIR projects were constructed on low to moderate volume roads between 1981 and 2001. / NOTE:Final rept. |
