Research Report 150 Verification of road roughness by profile beam during construction

Published: | Category: Activity management , Research programme , Research & reports | Audience: General

The correlation between road roughness, as measured by the NAASRA roughness meter, and the profile factor, measured by profile beams, was investigated between 1992 and 1995. Field trials were carried out in the Wellington region, New Zealand, to measure roughness before and after shape correction at 10 construction sites. The conclusion is that the 2 m profile beam is a suitable tool to verify road roughness during construction.
