iENGINEERING successfully completed the SDR-34 data release and additional application updates for LTPP InfoPave on July 27, 2020. This release contains updates, additions, and changes made to the Pavement Performance Database (PPDB). Maintenance updates were also applied to the LTPP InfoPave website.

The Long-Term Pavement Performance (LTPP) program collects a large amount of pavement performance data that includes inventory, maintenance, monitoring, rehabilitation, materials testing, traffic, and climatic data. This data has been made available by the Federal Highway Administration (FHWA) for pavement engineers, researchers, and other interested agencies. For this purpose, the data is released every year in the form of Oracle database dumps as part of the Standard Data Release (SDR). The SDR is also available in Microsoft Access and SQL Server formats for end-users. The SDR release includes updates to the Pavement Performance Database (PPDB), Ancillary Information Management System (AIMS), Reference Library, and resolution of various data and UI-related queries.
