FOREWORD

This document provides an overview of the contents of the Long-Term Pavement Performance (LTPP) program ancillary information. Ancillary information consists of data, images, reference materials, resource documents, and other information that support and extend the data stored in the Pavement Performance Database related to understanding the performance of pavement test sections included in the LTPP program. The primary purpose of this document is to explain the types and nature of the available information.

The LTPP program is an ongoing and active program. To obtain current information and access to other technical references, LTPP data users should visit the LTPP Web site at https://www.fhwa.dot.gov/research/tfhrc/programs/infrastructure/pavements/ltpp/. LTPP data requests, technical questions, and data user feedback can be submitted to LTPP customer service via e-mail at ltppinfo@dot.gov.

INTRODUCTION

Understanding why some pavements perform better than others is essential to building and maintaining a cost effective highway system. In 1987, the Long-Term Pavement Performance (LTPP) program—a comprehensive long-term study of in-service pavements—began a series of field experiments monitoring more than 2,400 asphalt and portland cement concrete pavement test sections across the United States and Canada. The primary purpose of the program is to establish a national long-term pavement database to support pavement research efforts that result in products to improve pavement performance. After more than 20 years of operation, the LTPP program has amassed a large volume of data. While much data are stored in an electronic relational database, an even larger amount of ancillary information exists and is available to those interested in the complex details of LTPP data. The purpose of this document is to describe the available LTPP ancillary information.
