The Select and Download Data feature contains data tables that are organized hierarchically under the Structure, Climate, Traffic, and Performance categories.

The Data Selection and Download feature contains data tables that are organized hierarchically under the Structure, Climate, Traffic, and Performance categories.

LTPP Section Summary Report feature provides data in both tabulated and graphical formats. In addition, this feature provides the ability to compare up to four sections side-by-side and up to 12 sections to export to Excel. Summary data can be displayed and downloaded in original (default) LTPP units, US Customary units, or the Metric system.

This feature provides the ability for users to visualize the extent of LTPP data that is available for a given category such as Structure, Traffic, Climate, and Performance based on the selected filters and resultant test sections.

Section Timeline provides the event history of each LTPP section including the construction, maintenance or rehabilitation, and monitoring activities that took place. 

The LTPP Transverse Profile Viewer visualizes the images and data collected by the Transverse Profile Measurement System (TPMS) onboard the LTPP High-Speed Survey (HSS) vehicles.

This feature is based on the LTPP Strategic Data Analysis Plan. It organizes all the ongoing and completed research projects and ideas for future research according to various topics. The feature lets users find research that is completed, in progress, or planned using LTPP data. A pivot chart is used to sort research projects based on user selected criteria.

Trend Analysis feature allows the user to visually analyze LTPP data using different types of dynamically generated graphs and charts. The feature includes Bar Charts, Scatter Plots, and Time Series for visualizing the selected data on selected test sections.

The LTPP Jointed Concrete Pavement PMED Calibration feature is designed to provide the performance data and inputs from the LTPP database for the AASHTOWare Pavement ME Design (PMED) software.

Correlation Analysis allows users to visualize the relationship among multiple data attributes based on the selected test sections. The feature provides pre-defined data attributes, and users can select up to five of these attributes for correlation analyses.

The LTPP Climate Tool is an online tool hosted on LTPP InfoPave that provides users with access to processed versions of MERRA data using different visual features and interfaces. 

LTPPBind Online is a web-based tool to help highway agencies select the asphalt binder Performance Grade (PG) for a particular site based on the AASHTO M323-13 standard.

MERRA Climate Data for MEPDG Inputs enables users to download MERRA climate data in a format that is being used as an input for the AASHTOWare Pavement ME Design Software. This feature allows users to download the Hourly Climatic Database (.HCD) file based upon MERRA data for the selected section.

This feature provides XML files to directly load the normalized axle load distributions into the AASHTOWare Pavement ME Design software.

What's New feature highlight the newly added documents, guides, protocols, manuals, brochures in the Referenece Library.

The Reference Library hub is a repository of LTPP operational documents, data collection guides, test protocols, manuals, research reports, tech briefs, and other program documents. The library is organized into categories for easy access.

The documents included in the InfoPave Library are LTPP publications; there are many more publications utilizing LTPP data published by NCHRP, TRB, and State DOTs, among others.

LTPP Literature References feature provides information on national and state-level publications or other sources of information describing how LTPP data is being used.

This feature provides direct access to the LTPP monitoring schedules, contacts and related information.

Materials Reference Library provides the information on the quantity and availability of pavement materials. 

This feature provides the most current list of the LTPP Directives.

Access to the data set generated from the study through data export (Excel and Access) and search entitled, "Interstate Condition Sampling Data."

This feature provides access to C-LTPP data through data export (Excel and Access), map, and search. In addition, access to C-LTPP related documents is provided.
