The project was aimed at providing an understanding of 'remaining service life' as a concept and definitions of key terms such as 'design life', 'service life', 'remaining service life (RSL)', 'designated level of service', and 'threshold distress values' in the context where RSL is restricted to the next intervention by rehabilitation or replacement. The estimation of RSL was noted not to be a precise process but it could be improved by understanding the relevant pavement distresses beyond which the pavement exceeds its designated level of service and rigorous observation of the deterioration of various road types.
