| 摘要： | This summary presents the results of the first data analyses of the Strategic Highway Research Program Long-Term Pavement Performance (LTPP) project. Data analyzed included information collected up to 1992. These analyses included: 1) developing a data analysis plan, 2) receipt and processing of data into suitable data bases for analysis and conducting statistical evaluations of the data bases, 3) using the LTPP data to evaluate the American Association of State Highway and Transportation Officials (AASHTO) design equations, 4) conducting sensitivity analyses to identify the independent variables that have significant impacts on pavement performance and to quantify the relative impact of each, and 5) using the experience gained from these early data analyses to recommend concepts for future data analyses. |
