This report documents the assessment of RSL of pavements where the RSL is confined in its estimation to the occurrence of the next major intervention either by rehabilitation or replacement. There are many measurable surface distress conditions, such as roughness, rutting, deflection and cracking, that can initiate major intervention. As also noted above, major intervention can be initiated by changes to the designated level of service required from the pavement which causes the current pavement to be sub-standard with respect to its revised designated level of service.
