The Data Collection and Investigations Section is a component of the Field Operations Sub-Unit of the Materials and Tests Unit. It is responsible for performing research into new materials submitted for use in our highway system. This consists of identifying the need, preparing a work plan, initiating research, performing, and monitoring the research, analyzing the results and implementing any new or modified procedures or specifications as a result of the research. Additionally, this Section is responsible for initiating engineering investigations to determine the reasons for poorly performing materials or manufactured products which fail to perform as designed and develop specifications or procedures to revise or correct the problem. The Data Collection and Investigations Section is also responsible for coordinating the Materials and Tests Unit's involvement with contract research with FHWA, ITRE, Universities and other Units within the Department of Transportation. Additionally, it is responsible for performing a variety of field inspections and testing; this includes, but not limited to, video pipe inspections, drilled shaft inspections, MIT scans, latex modified concrete pull-out testing, concrete and bituminous coring, and concrete maturity. Data Collection collects roughness (IRI) and rutting data on the secondary (SR) system, and skid friction data on the primary network (Interstate, US and NC routes). Also conducts training and QC/QA operations for the NCDOT Pavement Condition Survey.

The Manufactured Products Group is responsible for the inspection and approval of metal, concrete, plastic, timber, and composite products and their fabrication facilities. This group is also responsible for the development and management of the RFID/barcode product tracking program and mobile computing applications for sampling, testing, acceptance, and tracking of products, materials, and samples.
In 2016 the Materials and Tests Unit implemented a new inspection process utilizing Radio-Frequency Identification (RFID) tags on precast concrete materials. The RFID program involves the producer recording Quality Control information required by NCDOT and saving this information with the RFID tag. Materials and Tests inspectors then review the quality control information before their inspection and records the inspection results with the same RFID tag. Once delivered to a project NCDOT inspectors can use the RFID tag to verify the item has been accepted and is authorized for use on an NCDOT project. In 2018 the program was expanded to include prestressed concrete materials and more materials will be added to the program in the future.
The metals products inspection team is responsible for the following products:
- Galvanized Metal Products including:
- Gray Iron Castings and Welded Steel Frames and Grates
- MSE Wall Metal Straps for Corrosion Monitoring
- Signs and Sign Structures
- Steel Girders, Steel Piles, Expansion Joints, etc.
The metals products inspection team is also responsible for the following inspection and certification schools:
Concrete Products The concrete products inspection team is responsible for the following products: - Prestressed Concrete Products including:
- Precast Concrete Products including:
- Segmental Retaining Wall Blocks
- Solid Concrete Masonry Bricks and Blocks

The Field Operations area is responsible for sampling and testing the various materials used in the construction and maintenance of our highway system and for conducting Technician Assessments. In order to accomplish this tremendous task, this section is divided into four geographical regions. Each region is managed by an Area Materials Engineer and consists of three to four Sections that each correspond to a NCDOT Division. Each section is comprised of a Section Materials Specialist and one or two Materials Technicians. Each section has the responsibility of inspecting materials produced at all the quarries, sand pits, ready-mixed concrete plants, corrugated metal pipe plants, corrugated plastic pipe plants, concrete pipe plants, precast concrete plants, seed companies, and other specialty plants and manufacturers in their area. Additionally, these inspectors travel to various production facilities throughout the eastern and mid-western United States. The Field Operations area is also responsible for conducting Technician Certification classes throughout the State.
