The Long-Term Pavement Performance Information Management System (LTPP IMS) Data Users Reference Manual contains an overview of the LTPP program and the data available to researchers. LTPP is a 20-year study of pavements to improve design, rehabilitation, and maintenance practices. This document is intended to assist researchers in understanding the data that are currently available for General Pavement Studies Experiments and how to obtain it. The General Pavement Studies are a group of asphalt concrete (AC) and portland cement concrete (PCC) experiments using in-service pavements. In addition to materials test results for the pavement sections, data on pavement history, maintenance, and rehabilitation are stored in the IMS. Information on distress, transverse profile, cross profile, pavement deflection, and traffic is collected on a routine basis and added to the data base regularly. The manual includes information on the quality control process.

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 National Pavement Performance Database (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.

Sponsored by the Highway Division of ASCE; Long-Term Performance Program of the Federal Highway Administration. This collection contains papers from the International Contest on LTPP [Long-Term Performance Program] Data Analysis 1998-1999. This competition involved university students in the analysis of data in the LTPP database. Topics include: effect of locked-in curvature on portland cement concrete pavement; evaluation of a pavement performance prediction model using LTPP data; prediction of pavement performance?a neural network approach; and effectiveness of preventative maintenance strategies for asphalt concrete pavements based on LTPP distress data.

This report provides an overview of the first 5 years of the Strategic Highway Research Program Long-Term Pavement Performance (SHRP-LTPP) program. The background, LTPP history, activities and approaches, and decision-making processes of the program are detailed. Included are summaries of the studies initiated for general and specific pavement types, the characterization of pavement materials, monitoring activities, the LTPP database and Information Management System, data analysis, traffic data collection and analysis, as well as a summary of the contributions made by international participants. The general LTPP program is described and the expected results, products, and benefits are also outlined.
