A multi-year Accelerated Pavement Testing research programmewas initiated to study the behaviour of rehabilitated LightlyCemented Pavement (LCP) structures. The aim of this work was toquantify the structural behaviour of these rehabilitated pavements,and to optimise the life-cycle cost for the road agency.

The main findings were that the rehabilitated LCPs tested inthe study only failed in terms of permanent deformation due topumping of fines in the wet condition (G1 crushed stone and thin(< 50 mm) asphalt rehabilitation options) and bleeding of thedouble seal (double seal rehabilitation option).

The economic analysis of these rehabilitated LCPs, indicatedthat the double seal rehabilitation option is the most economicaloption for traffic classes with equivalent traffic demands lessthan or equal to 10 million equivalent standard axles, while theG1 crushed stone rehabilitation option was the most economicaloption for 10 to 30 million equivalent standard axles.
