- W2244637932 abstract "Highway roughness measurements were made in Bolivia in the Districts of La Paz, Cochabamba, and Santa Cruz (1) using a Mays Ride Meter. The work was sponsored by the International Bank for Reconstruction and Development (IBRD) as part of a pavement maintenance project with the Servicio Nacional de Caminos, Bolivia (7). Several measurement results are presented. These include Mays Meter calibration results using the TRRL pipe course, both prior to and after completion of a large survey. Roughness versus speed information taken during the calibration and roughness measurements from paved, gravel, and earth roads are presented. The effectiveness of motor-grader operations in reducing roughness is discussed. A preliminary roughness scale developed for use in Bolivia is presented and compared with a Kenya roughness scale developed by the IBRD (8). Conclusions drawn from the paper include the establishment of tentative roughness limits for roads in Bolivia and similar countries. The measurements obtained were successfully used with IBRD maintenance programming in Bolivia. Since the completion of the work presented in this paper, further measurements have been made for planning and study purposes. /Authors/" @default.
