Loss of the overall bearing capacity; in this case, due to the high rigidity of the cement concrete pavement, it is more troublesome to deal with, local excavation, grouting and other treatment methods can no longer restore its use function, and the repair process is also complicated and costly . The damaged cement concrete pavement is a resource placed manually. Even if it is removed, it should not be simply "buried". In order to make the best use of it and save resources, the damaged and waste cement concrete pavement is broken into aggregates and remixed to prepare stable materials. Or recycled concrete is reasonably used in the corresponding structural layer of the new pavement to achieve resource regeneration and conform to the circular economy model.
