| 摘要： | As part of the European Concrete Pavement Evaluation System (COPES) program, 77 concrete pavement sections from France, Italy, the United Kingdom, and Belgium are being monitored and the data evaluated with the objective of providing continual improvements to the design, construction, and maintenance of concrete pavements. An overview of the data collected under the European COPES program is presented, and a general look at overall performance trends is provided. The European sections are all characteristic of the wet-freeze environmental region. Because of higher legal axle weights and longer design periods, European pavements are often exposed to many more equivalent-single-axle-load applications than pavements in the United States. Of the sections evaluated, the most common pavement type is jointed plain concrete pavement. Extensive use of stabilized bases, positive drainage features, and dowel bars is also evident. A qualitative analysis was conducted using present serviceability rating (PSR), age, and traffic as the principal parameters. The use of lean concrete bases and incorporation of a greater number of modernity elements (e.g., dowel bars and positive drainage) were found to improve the performance of the sections. Models predicting the PSR of the pavement sections were also developed. |
