16. Abstract This document provides guidelines and forms for documenting maintenance and rehabilitation treatments on test sections in the Long-Term Pavement Performance (LTPP) program and is an update to chapters 6 and 7 of the 1993 version of the LTPP Data Collection Guide. The terms maintenance and rehabilitation are used within the LTPP program to classify how various treatments which alter a test section's structure are documented in the database. This is an important distinction, since classification of some of these treatments may differ from highway agency terminology. For example, thin overlays that some agencies may classify as maintenance are classified within the LTPP program as rehabilitation, since the data forms for overlays of any thickness are the same. |
