Abstract

Evaluation of pavement roughness is essential in road management, both for the understanding of pavement response under loading and for the definition of maintenance and rehabilitation strategies. Several techniques have been proposed and implemented into practice, ranging from simple rod and level static measurements to more advanced high-speed non-contact surveys. Although analytical tools have been derived for rigorously describing road surface profiles, they are still difficult to implement into ordinary pavement management systems due to associated financial and technical constraints. In order to improve this situation the Authors developed a new response-type road roughness measuring system, which is a simple and economic tool for rapid profiling applications. Investigations reported in this paper show that the new device is capable of providing a reliable description of road surface profiles, both in terms of spectral components and indirect statistics, leading to a straightforward assessment of roughness-induced dynamic amplification of vehicle loading.
