Major rehabilitation

Major rehabilitation is a technique used to improve the structural capacity of a pavement to help extend the service life or improve load-carrying capacity. Bonded and unbonded concrete overlays can be suitable techniques for major rehabilitation. These concrete overlays are typically thicker than those used for preventive maintenance or minor rehabilitation due to the required increase in structural capacity. If structural capacity only needs to be restored or if surface irregularities need to be addressed, preventive maintenance or minor rehabilitation may be more suitable techniques .
