Visit the New LTPP Community of Practice

To assist users of the Long Term Pavement Performance (LTPP) program's Standard Data Release (SDR), the LTPP program has introduced a new Community of Practice Web site. The Community of Practice provides SDR users with a forum to post questions and share experiences in using the LTPP database, which contains millions of records of data collected by the LTPP program. The latest edition of the database available is SDR 20, which can be obtained as a six-CD set or as a single DVD and one CD. The SDR is in Microsoft Access(r) format. New features on the latest release include a Reference Library CD, which gives users the capability to search for software utilities, resource documents, and research reports that support the database.

To visit the Community of Practice online, go to (under "Highway Community Exchange," select "LTPP Standard Data Release"). If posting a question or comment, site visitors should indicate which version of the SDR they are using. To obtain a copy of the SDR, contact LTPP Customer Support Services at 202-493-3035 (fax: 202-493-3161; email:
