Use of PMS Data for Performance Monitoring with Superpave as an Example. Volume 1

摘要

The objective of this project was to examine how existing pavement management data and materials related data in various state DOTs can be used to evaluate the performance of new materials and concepts and to validate new design methods. In particular, Superpave is used as an ideal example and is carefully examined. This study is not big enough or long enough to evaluate or validate Superpave per se. Rather we examine the process and obtain consensus on what data states would need to collect to adequately evaluate Superpave. Similar studies could be done for any other new design or materials concept such as the 2002 Pavement Design Guide. No evaluation or judgment is made about Superpave, rather the concepts and details of using pavement management and related data are clearly illustrated. A second objective of the study is to determine what PMS data and other related data and factors the state DOTs collect on a common basis, which could be combined and used for multi-state data analysis. A third objective is to determine what can be done to make data from several state DOTs compatible and usable to others to the point that a common analysis could be made for the broader benefit of all state DOTs and thus the Federal Highway Administration.
