SOME OPERATIONAL LIMITATIONS OF THE NAASRA ROUGHNESS METER

The National Association of Australian State Road Authorities (NAASRA) roughness meter is often required to be operated at low speeds, with acceleration and deceleration from and to a standing start, and through a tortuous pavement alignment. This project investigates the effect of these operational limitations on the determination of the true roughness level. It concludes that operational limitations which restrict the speed of the survey vehicle have a significant effect on the determination of the true roughness. The implications for the determination of trends in a network survey and for project evaluation are discussed. (a)
