InfoMaterials™ Update Notes
August 2025
As part of FHWA InfoMaterials™ 2025 release, one new dataset has been added and four existing datasets have been updated. A brief description of each dataset is given below:
Mobile Asphalt Technology Center (MATC) Dataset: The MATC dataset is processed and augmented with new 2025 data. The 2025 data is collected from FHWA MATC Materials Testing projects in New Jersey, Wisconsin and Wyoming.
Alkali-Silica Reaction (ASR) Dataset: This is a new dataset added with 2025 data from California, Massachusetts, Pennsylvania, Connecticut, Maine, North Carolina and New York. It is the largest publicly available database consolidating such information pertaining to the ASR behavior of aggregates and is useful for evaluating the alkali-silica susceptibility of aggregates. The relevant links, papers and standards have also been uploaded under the “References” tab as an addendum to this new dataset.
Mobile Concrete Technology Center (MCTC) Dataset: The MCTC dataset is processed and augmented with new 2025 data from on-site Materials Testing projects by FHWA.
Continuous Friction Measurement (CFM) Dataset: A new 2025 sub-dataset has been added to the existing CFM dataset. This new 2025 CFM dataset will be displayed by default when users select the CFM dataset on InfoMaterials. Users will be able to navigate to previous CFM datasets (i.e., 2020, 2022 and 2024) using the dropdown.
Erosion Function Apparatus (EFA) Dataset: The EFA dataset is processed and augmented with new 2025 data. New data records were added for Soil and Erosion Testing Services for Bridge Scour Evaluations (TPF-5(461)).
August 2024
As part of FHWA InfoMaterials™ 2024 release, three existing datasets have been updated. A brief description of each dataset is given below:
Mobile Asphalt Technology Center (MATC) Dataset: The MATC dataset is augmented with new 2024 data. The 2024 data is collected from Arkansas, Connecticut, New Hampshire, and Wyoming.
Mobile Concrete Technology Center (MCTC) Dataset: Updates to the MCTC dataset include the addition of new data records and new data fields, as well as changes to the existing data. First, several new data fields are added to the existing dataset, namely Requesting Entity, Latitude, Longitude, Phoenix, and Direction of Travel. Second, the existing VISIT_ID field name is now replaced with and referred to as MIX_ID. Finally, projects KS1402, NY0902, and WA0802 are removed from the MCTC dataset.
Continuous Friction Measurement (CFM) Dataset: A new 2024 sub-dataset is added to the existing CFM dataset. This 2024 sub-dataset is displayed by default after selecting the CFM dataset as indicated by the dataset dropdown at the top of the CFM dataset page.
September 2023
As part of FHWA InfoMaterials™ 2023 release, three new datasets have been added and one existing dataset has been augmented. A brief description of each dataset is given below:
Mobile Asphalt Technology Center (MATC) Dataset: This existing dataset has been augmented with the results of FHWA MATC Materials Testing Projects for 2022. The data from Washington, Arizona and Mississippi has been added in this dataset.
Dynamic Modulus Test and Cyclic Fatigue Test Refinements (DMCF) Dataset: This dataset contains experimental results from the small-scale Dynamic Modulus Ruggedness/Interlaboratory Study and Cyclic Fatigue Temperature Study.
Erosion Function Apparatus (EFA) Dataset: Erosion Function Apparatus dataset contains three subsets from Geotechnical Laboratory. The first data subset contains the results from FHWA Geotechnical Laboratory’s portion of the TPF study on Soil and Erosion Testing Services for Bridge Scour Evaluations (TPF-5(461)). The second data subset contains the FHWA In-Situ Scour Testing Device (ISTD) demonstrations as part of the Accelerated Market Readiness (AMR) Program. The third data subset is a file-based dataset and it compiles the results from the NCHRP 24-43 (Relationship between Erodibility and Properties of Soils) study as well as additional erosion tests conducted at Texas A&M University.
Large-Scale Direct Shear (LSDS) Dataset: LSDS dataset contains three subsets from Geotechnical Laboratory. The three data subsets contain the results from large-scale direct shear (LSDS) tests conducted as part of the 2022, 2018 and 2015 studies of open-graded aggregates (OGAs) as structural backfill.
October 2022
As part of FHWA InfoMaterials™ 2022 release, two new datasets have been added and three existing datasets have been augmented. A brief description of each dataset is given below:
Mobile Asphalt Technology Center (MATC) Dataset: This new dataset contains the results of FHWA MATC materials testing projects since 2020, including asphalt mixture design and pavement construction data collected through the FHWA mobile asphalt program.
Dielectric Profiling System (DPS) Dataset: This new dataset contains the results of FHWA DPS testing projects between 2019 and 2021, including gyratory compacted samples (puck) testing data, field data, and analysis performed by the FHWA nondestructive evaluation program.
Traffic Speed Deflection Device (TSDD) Dataset: This existing dataset has been augmented with newly collected TSDD data based on 0.1-mile sections. Additionally, new TSDD and GPR data based on 10-meter sections has been added to this dataset.
Mobile Concrete Technology Center (MCTC) Dataset: Newly collected data since 2020 has been appended to this existing dataset.
Continuous Friction Measurement (CFM) Dataset: Newly collected data for 2022 has been added to this existing dataset. This new 2022 CFM data is based on 10-meter sections as compared to the existing 2020 CFM data, which is based on 0.1-mile sections.
