Summary
| Description |
English: From the beginning, the Office of Public Roads included a group of men to develop new techniques through experiment and research. Historically, this activity has involved a strong element of “let’s try it and find out” as illustrated in this early bituminous macadam pavement experiment. Today’s broad program of research and development dealing with problems of safety, traffic management, environmental protection, materials, structures, and maintenance uses modern, scientific techniques in searching for solutions. |
