Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   The Standard Data Release (SDR) is the annual release of the Long-Term Pavement Performance (LTPP) program database. The SDR is available annually to the public in Microsoft Access® format and available on digital versatile discs (DVD) and/or universal serial bus (USB) drives.  SDR can be obtained through LTPP customer support services at ltppinfo@dot.gov.Perhaps one of the most useful documents contained here for beginners is the "Accessing LTPP Data" tutorial, which includes step-by-step examples of working with the SDR in Microsoft Access® and building queries for data extraction. The first document to read is the "Release Notes," which comes in hardcopy and electronic format with the SDR. These notes contain important information about organization, content, and significant changes that have occurred from release to release.A Reference Library DVD read-only memory accompanies the standard data release and gives the user the capability to search for software utilities, resource documents, and research reports that support the database.
Goals:  
The Long-Term Pavement Performance (LTPP) Program makes the world’s largest pavement performance database available annually to the public in Microsoft Access® format and available on digital versatile discs (DVDs) and/or universal serial bus (USB) drives.
Product Type:   Data
Research report
Test Methodology:   Field performance data collection is uploaded in to the Long-Term Pavement Performance database.
Expected Benefits:   The expected benefit is data on pavement performance.
Deliverables:   The Long-Term Pavement Performance (LTPP) Program makes the world’s largest pavement performance database available annually to the public in Microsoft Access® format.
