The Physical Research Section is responsible for planning, coordinating, conducting, and implementing the Division of Highways’ program of operational research and development. The goal is to improve the economy and quality of transportation design, construction, maintenance, and operation.

The Physical Research Section’s program consists of individual projects, each of which is directed toward the solution of a specific problem. Some studies are conducted by Departmental forces, and others by outside agencies under contract with the Department. The majority of Department projects are conducted by the Physical Research Section. The remaining projects are conducted by other Bureaus, Districts, Offices, and Divisions with coordination by the Physical Research Section as needed. The gathering of data is sometimes assigned to District offices. Research projects requiring specialized knowledge or equipment (not available elsewhere within the Department) are contracted to outside agencies, with direction provided by the Physical Research Section.

The Physical Research Section includes four functional Units, each having specific responsibilities. These Units are Bridge Investigations, Pavement Technology, Products Evaluation, and Technical Services.
