Products derived from the Long-Term Pavement Performance (LTPP) program have been made available to State departments of transportation and other segments of the highway community since the early years of the program. Initially, these were methods, guidelines, and procedures for standardized testing and performance data collection. While these procedures were developed to meet LTPP data-collection needs, their conversion into standard practices has been an American Association of State Highway and Transportation Officials (AASHTO) activity. Some products and benefits from LTPP already implemented in practice are based on best-practice construction specifications developed for the pavement experiments requiring new construction, while other products were developed from early analysis of LTPP data.

Throughout the life of the LTPP program, significant efforts have been made to improve data accessibility for all potential users. At least once a year for more than a decade, standard data releases containing data from the LTPP database have been made available on DVDs, USB drives, and more recently, the Internet.


LTPP's products and software available at LTPP Products Online include:


  • LTPP InfoPave™
    Launched in 2014, LTPP InfoPave™ enables users to easily tap into the wealth of pavement performance data and knowledge available by the LTPP program. The Web-based system offers a gateway to data from the LTPP test sections, as well as findings from data analyses and extensive documentation for the many aspects of LTPP experiment design, data acquisition, quality control, and data dissemination. The new site for LTPP InfoPave™ is https://infopave.fhwa.dot.gov.  Visitors will also find information on LTPP InfoPave™ Mobile, a companion application for smart phones. Contact Jane Jiang at 202–493–3149 or jane.jiang.@dot.gov.

  • LTPPBind
    A Windows-based software program that provides users with the ability to apply regional temperature and traffic conditions to select Superpave performance-grade asphalt binders.

  • Rigid Pavement Design Software
    A Microsoft Excel spreadsheet that automates the design and analysis procedures for improved guidelines for pavement cement concrete pavements as published in the 1998 Supplement to the AASHTO Guide for the Design of Pavement Structures, Part II - Rigid Pavement Design & Rigid Pavement Joint Design.


Other LTPP products are available at the links below:


  • Distress Identification Manual for the Long-Term Pavement Performance Program (Fifth Revised Edition)
    Manual developed to provide a consistent, uniform basis for collecting distress data on the LTPP program. The manual provides a common language for describing cracks, potholes, rutting spalling, and other pavement distresses.

  • FWD Calibration
    New information and video that present the LTPP Falling-Weight Deflectometer (FWD) calibration procedure.

  • LTPP Product List
    List of products developed using LTPP data, guidelines, protocols, etc.

  • Pavement Manuals of Practice
    A series of four manuals that provide the latest information on pavement maintenance and repair.

  • Product Briefs
    Overviews of LTPP product offerings, including technical background information, along with key features and product benefits.

  • Product Plan
    The LTPP program’s guiding document to develop products for the highway community.

  • Resilient Modulus
    Research report and videotapes that explain the details of LTPP's revised unbound resilient modulus laboratory tests and procedures.
