| Release 17.0 - 2/24/2004 - LTPP DataPave Online Release 17 |
The January 2004 Data Release is the 17th national release of data from the LTPP program. This release contains some revisions to data included in the July 2003 data release. No changes or updates have been made to data in the climatic and dynamic load response modules.
Data Release 17 contains, for the first time, the data from Superpave related asphalt binders and mixtures. This data includes test results from the dynamic shear rheometer, bending beam rheometer, direct tension, gyratory compaction, and volumetric and gravimetric properties of gyratory compacted specimen. This data represents only a partial set of available data. LTPP contractors are still in the process of entering these data and resolving errors. More data are expected to be included in the next release. Data users are encouraged to contact LTPP Customer Service with questions or problems that
they may find in the contents of these new tables.
This is the first data release that includes the results of quality checks on data from supplemental test sections constructed on the Specific Pavement Studies sites. SPS-9 construction data was first released in the July 2003 data release. Work continues on entering SPS-9 construction data to the SPS module. Processing of traffic monitoring data collected between 1999 and 2002 has been substantially completed. Work continues on loading and resolving errors in “problem” data sets from this time period. More traffic monitoring data is expected to be available in the next data release.
An
LTPP IMS Data Disclaimer and a
Data Analysis/Operations Feedback Report instruction letter and form are also included in the Release 17.0 for information.

| Release 16.0 - 12/16/2003 - LTPP DataPave Online Release 16 |
The July 2003 release is the 16th national release of data from the LTPP program. This release contains some revisions to the LTPP data included in the January 2003 release. It also includes new pavement monitoring, construction and materials test data collected through May 2003. No changes or updates have been made to the data in the climatic and dynamic load response modules.
Two new tables were added to the traffic data module. LTPP is in the process of implementing new and improved traffic analysis software and clearing the backlog of unprocessed traffic monitoring. These two tables contain the output from the new analysis software for pre-1998 data previously processed using the old software and post-1998 data that had not previously been released. It is anticipated that the backlog of un-processed traffic monitoring data will be cleared in 2004. Some of the tables containing data created by the old traffic analysis software have been removed from this release.
This release also contains the data from all of the SPS-9 construction data tables. Entry of available SPS-9 construction data is expected to be completed by January 2004. |
