Products derived from Long-Term Pavement Performance (LTPP) program have been flowing to State transportation departments 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 or thumb drive.


LTPP's products and software available at LTPP Products Online (http://www.ltpp-products.com) include:

  • LTPP InfoPave™ Goes Live
    LTPP InfoPave made its debut at the 93rd TRB Annual Meeting in January. The system allows users to more easily tap into the wealth of pavement data available through FHWA’s Long-Term Pavement Performance (LTPP) program. LTPP InfoPave 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. To start exploring LTPP InfoPave, visit www.infopave.com. Visitors will also find information on LTPP InfoPave Mobile, a companion application for smart phones.

  • 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 PCC 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.
