The 2025 LTIP Student Data Analysis Contest is underway. The contest encourages university students to use data from the Long-Term Pavement Performance (LTPP) InfoPave™ or Long-Term Bridge Performance (LTBP) InfoBridge™ web portals to study the various factors affecting pavement and bridge lifecycles and to develop a technical paper that documents their research. Entries are due Friday, August 1, 2025.

Please join us on Thursday, December 12, 2024, 2–3 p.m. Eastern Time, to learn about the recently completed LTPP program’s layer moduli backcalculation effort.

The goal of the LTPP program is to understand how and why pavements perform as they do. In support of this goal, the program has assembled a database since 1989, which today is the world’s premier source of pavement performance information; but using it is often not easy due to the required data wrangling (i.e., finding, extracting, merging, and interpreting available data necessary to develop analysis input datasets.)

The LTPP MRL has moved to a new location in May 2019. It is currently in the process of reorganizing its inventory and installing pallet racking - a process which has taken several weeks. However, the facility is in operation during this process. At this time, fulfillment of material request is limited by the maneuverability of containers within the confined storage space. Shipment of requested materials may be delayed depending on the size of the material request.

"The FHWA purchased four Transverse Profile Measurement Systems (TPMS) in late 2017. These laser-based systems have been installed on each of the four High-Speed Survey (HSS) vehicles that were already collecting pavement longitudinal profile and macrotexture data for the LTPP program. A single transverse profile consists of 2048 transverse data points obtained at 0.98-inch longitudinal intervals triggered by the signal from the Distance Measuring Instrument (DMI) in the HSS vehicle. This replaces the old manual Dipstick method for collecting transverse profile data and provides enhanced safety for the LTPP program.

With Standard Data Release 33, this data is now available for select sections in LTPP InfoPave™. You can find this data in the Data Selection and Download feature in the Performance tab under Transverse Profile.

Since the official recruitment of the of the Long-Term Pavement Performance (LTPP) program’s new warm-mix asphalt (WMA) experiment in January 2014, two sites have been constructed. A site in New Mexico was completed in November 2014 and one site in Texas was completed in February 2015. Pavement performance and materials sampling data are being collected at both test sites and these data are being added to the LTPP database.

The LTPP program is still receiving nomination packages from the States and Provinces to fill the experimental matrix, but the program has not received many nominations for sites in the wet-freeze region of the country. These sites are needed in order to gain the full benefit of this experiment. Thus, the LTPP program is asking States and Provinces in the wet-freeze area of the country to look at their construction projects and identify those that are potential candidates for the WMA experiment.

For more information about this new experiment and how your highway agency can partner with the LTPP program in evaluating the long-term performance of these new paving materials in real environments and under real traffic loads, contact Jack Springer at jack.springer@dot.gov or 202-493-3144.

The North Dakota Ready Mix & Concrete Products Association in conjunction with the North Dakota Chapter, Inc. - American Concrete Pavement Association (ACPA) will be hosting the North Dakota SPS-2 Concrete Pavement Tech Day on December 16, 2014 in Bismarck, North Dakota. The event will provide the history and performance of the North Dakota SPS-2 Long Term Pavement Performance (LTPP) Concrete Pavement Experiment. It is a unique opportunity to learn about and evaluate first hand the performance of a national concrete pavement experiment.

Background
The LTPP SPS-2 Experiment is the largest ongoing concrete pavement research program in the United States. Fourteen States constructed this experiment. In 1994, the North Dakota Department of Transportation constructed eighteen (18) test sections on Interstate 94 East Bound, approximately 16 miles west of Fargo, North Dakota. These test sections were constructed as part of the national Long Term Pavement Performance (LTPP) SPS-2 Strategic Study of Structural Factors for Rigid Pavements. North Dakota’s test sections are now 20 years old and are still actively being monitored by Long Term Pavement Performance (LTPP)."

The Arizona Pavements/Materials Conference on November 19-20 will include a presentation on the SPS-10 projects planned for construction in 2015 and 2016.  These projects compare the performance of warm mix asphalt overlays to the performance of conventional hot mix asphalt overlays.  Arizona’s SPS-10 projects will also include supplemental test sections studying the impact of higher recycled asphalt pavement (RAP) percentages.

The presentation will be given by Kevin Senn, Project Manager for the LTPP Western Regional Support Contract at 2:00 PM on November 19.

The interactive Long-term Pavement Performance (LTPP) Data Analysis Strategic Plan provides visual insight into research conducted, underway, and proposed using the LTPP data.  This tool provides an organized and easy-to-understand interface to search and explore LTPP research by data analysis objectives and priorities.
