Abstract. This paper presents the performance of three rehabilitation methods on six highways to restore the condition of concrete pavement: (1) polyurethane injection (PFI), (2) dowel bar retrofit (DBR), and (3) full depth repair (FDR). PFI was able to raise the slabs to the target levels; however, it was not able to maintain the slabs at the …

Full depth repair is recommended in case a weak concrete is identified at the site of distress or the pavement have multiple type of distresses such as cracking, breaking of joint, locking of joint, etc. . Repair of full depth transverse cracks requires new dowel bars to be placed and one new joint to be constructed.
