A Study on the Serviceability of Sediment Pavement on Farm Road

–Evaluation of the surface roughness by the longitudinal surface profile and the vibrating acceleration–

Abstract

Since the Serviceability of the sediment pavement on farm road is not clarified, a performance-based specification of the sediment pavement is not progressing. Pavement for an examination was carried out on the road of Tottori University, and the serviceability of the sediment pavement was evaluated. The measuring instruments that soil pressure meter and water meter were installed in pavement, and the state of stress and water content in the pavement was observed regularly. Moreover, the longitudinal surface profile and the vibrating acceleration were measured. This paper showed clearly that the longitudinal surface profile and the vibrating acceleration were normal distributions. And the Surface roughness was considered from the result.
