【 摘 要 】

The renovation of concrete pavements (typically motorways) is commonly done by deep replacement of the existing damaged concrete layers including underlying basal layers with newly installed layers with a new surfacing. This technology is rather expensive and time consuming. New alternative solution based on including of intermediate mechanically stabilised layer into road structure is presented. Full scale laboratory model of this structure has been realised. Results and observations are presented. Main contribution of new approach is possibility to remain old concrete layers on place and cover them by new pavement. Standard road structures where concrete layers are overlaid by new pavement in combination with long-term intensive dynamic loading and temperature changes are prone to reflective cracking. Proposed technology avoids that problem and enables cost effective reconstruction of damaged road.
