Development of road life curves and tolerability levels of road roughness

Road roughness surveys are carried out biennially with the latest survey being completed in 1980. The data collected is used to provide pavement age performance relationships and tolerability levels for determining rehabilitation and reconstruction strategies. This report contains preliminary statistics from the 1979/80 roughness survey and findings from the analysis of 1977/78 survey in an attempt to develop road life curves to be used in the evaluation programme NIMPAC. (A).
