Office of Materials and Research
Office Head: Georgene M. Geary, PE
The main task of the Office of Materials and Research (OMR) is to conduct sampling, testing, and inspection of highway construction materials to assure the quality of GDOT construction projects for the citizens of Georgia. As part of this, OMR also develops materials-related polices and specifications that are cost efficient without compromising the safety of the traveling public. The OMR administers the GDOT research program, which is geared toward the implementation of new technology, including improved highway materials and processes that will be more economical and environmentally friendly. The OMR also provides geotechnical engineering services to the GDOT including bridge and retaining wall foundation studies, soil surveys, lake siltation scour, and river migration studies.
The OMR has a staff of almost 400 employees who work in the Central Laboratory (Metro Atlanta) located in Forest Park, Georgia, or in one of six branch laboratories located throughout the state.
The OMR is composed of four Bureaus: Quality Administration, Technical Assistance, Testing, and Geotechnical.
In order to more effectively monitor quality, the OMR employs statistically based Rating Systems to evaluate all major construction items. Rating systems are presently in place for asphaltic concrete plants, ready mix concrete plants, aggregate sources, pavement smoothness, asphalt surface treatment construction, bridge deck steel cover, and concrete pipe and miscellaneous precast products. Products which meet the GDOT specifications are placed on the GDOT Qualified Products List. Only products on this list or those which have been uniquely certified by this laboratory may be used in GDOT construction projects.
Our mission .....
The mission of the Office of Materials and Research (OMR) is to conduct the necessary sampling, testing, and inspection to assure the quality of materials used in the Department of Transportation projects; to provide geotechnical engineering services to the Department; and to administer the Department's research and development program.

and evaluation of roadway and bridge construction items of a structural nature. These include structural steel bridge beams and girders, overhead sign supports, high mast lighting towers, steel and aluminum lighting and traffic poles, steel bearings for bridges and other welded construction items. The Structural Steel Unit also manages the Welder Certification program and provides Non-Destructive Testing for the Department.
Welder Certification - All welders involved in fabrication for GDOT construction projects must be certified on an annual basis. There are two categories of welders, shop welders and field welders. Shop welders are certified in their respective facilities prior to beginning fabrication of any welded roadway or bridge construction item. Field welders are certified at OMR and are required to have their certification card on their person whenever performing welding on a GDOT construction project.
Non-Destructive Testing - Non-Destructive Testing is performed in both the shop and field environments. Ultrasonic (UT), Magnetic Particle (MT), Dye Penetrant (PT) and Visual (VT) testing is performed by the Structural Steel Inspection Unit. Shop and field testing of structural steel beam and girder splices continues to be one of the most critical duties. In addition, technical assistance is provided to the Operations Division by performing UT evaluation of cantilevered sign structure anchor bolts and bridge pin and hanger connections.

TESTING MANAGEMENT BRANCH
The Testing Management Branch of OMR consists of six District Branch Labs and a Field Testing Unit located in District 7 at OMR (Metro-Atlanta). Each District Lab consists of a Laboratory and a Field unit except District 7(Field Only). All the Branch laboratories consist of a Soil, Concrete, Aggregate, and Asphalt sections. The Field Unit performs acceptance and quality assurance testing on airport, bridge and roadway construction materials within their respective Districts. The Testing Management Branch is also responsible for monitoring contractor acceptance testing of asphaltic concrete on all GDOT projects. The Testing Management Branch also oversees the Roadway Testing Technician and Quality Control Technician Level 1 certification programs.
Laboratory: The laboratory purpose is to test various materials used in roadway construction to ensure the quality of material being used meets standard specifications. The materials tested are preliminary, Classification, Comparison, AMRL and Cooperative type samples. The Lab determines the classification of various soils used in roadway construction. Soils and aggregates are tested to determine gradation analysis, maximum densification, optimum moisture, and volume changes. Asphalt is tested to determine AC content and gradation analysis, and concrete to determine the PSI.
Soils Test to determine the Classification, Clay content, Liquid Limits, Plastic Limits, Plasticity Index, Density and Volume Change on soils used in highway construction.
Concrete Receive and test concrete cylinder and bricks to determine if the PSI meets Department Specifications.
Aggregate - Determine the gradation analysis on aggregate and the theoretical density and optimum moisture on graded aggregate base and lime rock used in roadway construction.
Asphalt Perform tests on various asphalt plant produced mixtures to determine the gradation analysis and asphalt content for comparison. Design asphalt mixtures, test asphalt design field verification and bituminous materials.
Field: The Field Unit purpose is to sample and test roadway construction material to insure acceptability of material used in construction meets the Department Standard specification. This will ensure that the highest quality of material used will be incorporated into the work and construction achieves the specified end.
Roadway Sampling and Testing Field Testing Technicians are responsible for sampling and testing material used in roadway construction to verify that specifications are being met. Sampling and Testing materials are sometimes preliminary, acceptance and Quality assurance.
Asphalt Plant Sampling and Testing Field Testing Technician are required to inspect, sample and test material produced at an asphalt plant. The tests performed are quality assurance, comparison and sometimes acceptance. Quality assurance testing insures uniformity of testing between the Department and the Producer. Comparison testing helps determine if the test methods and equipment used are in accordance with Department policies.
