| 摘要： | Past pavement research efforts often were hindered by a lack of availability and access to comprehensive, diverse, and consistent traffic, materials, structural, and climatic data for different pavement types. A principal goal of the Strategic Highway Research Program's Long-Term Pavement Performance (SHRP-LTPP) study is to design a national database for the collection of information that will allow researchers to pursue long-term pavement performance studies with confidence. To this end, a major activity of SHRP-LTPP is the establishment of a National Pavement Performance Database (NPPDB). This report describes the information management system within SHRP-LTPP to service the NPPDB and the quality assurance checks that verify the presence, reasonableness, accuracy, and validity of the data prior to incorporation into the NPPDB. The NPPDB houses many types of data including inventory, materials characterization, longitudinal profile, deflection, cross profile, distress, friction, maintenance, rehabilitation, climate, and traffic. The report discusses data types and elements in detail and notes data sources. Equipment and operations of the NPPDB are described, as well as NPPDB products. |
