Long-Term Pavement Performance Information Management System User Guide available in PDF, EPUB and Kindle. This document provides information to aid in understanding and using the Long-Term Pavement Performance (LTPP) program's Pavement Performance Database (PPDB), LTPP Traffic Analysis Software (LTAS) database, and contents of the Ancillary Information Management System (AIMS) and LTPP InfoPaveTM. This report describes the structure of the LTPP program, the relational structure of the LTPP PPDB, the location of various data elements, contents of data tables, tips on efficient means of manipulating data for specific types of investigations, and information on how to obtain data. This is the final updated version of this report. The LTPP InfoPave website is now the official public data dissemination mechanism for LTPP data. Over the years of updates to this report, contributing authors included Travis Thompson, Amy Simpson, Beth Visintine, and Peter Schmalzer.

This book was released on 1997. Long-term Pavement Performance Information Management System Data Users Reference Manual available in PDF, EPUB and Kindle. 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.
