| 摘要： | State legislation was passed in Illinois in 1999 that required the use of performance-based warranties on at least 20 highway construction contracts arising out of the Department's 5-year project program for fiscal years 2000 through 2004. The warranty period was required to be at least 5 years, and 10 of the contracts had to be designed for a 30-year life cycle. Warranty specifications were developed for concrete pavements, bituminous (asphalt) pavements, and bituminous overlays. Detailed performance requirements and corrective actions for pavements in non-compliance were given in the specifications. The warranty specifications were included on 27 construction projects in FY 2000-2004, and 19 of the projects were designed for a 30-year life cycle. Included in the report are results of a brief survey conducted with the resident engineers on warranty construction projects. Over half of the projects were still under construction at the time of the report. Therefore, few conclusions can be made as to the effectiveness of the warranty specifications. The projects will be monitored, and further analyses will be made in the future to determine whether the specifications should be used on future IDOT projects. |
