Long-Term Pavement Performance Information Management System: Data Users Reference Manual

Primary Topic: Pavement Maintenance

Description: Superceded by FHWA-RD-03-088 (2003), Sept. 2005 update available from LTPP Customer Support Service Center. 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. One chapter discusses a related, but separate, traffic data base.

Data for all valid sections are available in various formats. A copy of a data request form is included, along with instructions on filling out the form and any applicable fees.
