The Office of Materials Technology is comprised of two distinct areas: Material Quality and Material Engineering.
Material Quality services are conducted through laboratory and field operations in all the major material disciplines — soils, aggregate, metals, structures, asphalt, concrete, coatings and pavement markings. These services are completed through inspection and sampling of materials, testing by standard methods and rendering final approval of all materials used in the construction and maintenance of roads, bridges and other structures in Maryland.
Material Engineering involves pavement, geotechnical and geological services that provide technical expertise, emergency response to geo-hazards, and advisory recommendations in the planning and design phases of highway transportation projects. Testing services include subsurface investigations, network level data collection for pavement & asset management objectives and non-destructive testing of structures.
OMT’s central laboratory is located in the SHA complex in Hanover, Maryland. In addition to conducting tests at the central lab, OMT oversees and reviews private lab testing results that support material quality operations.
OMT also provides these services to other transportation business units as well as Maryland counties and municipalities.
