===Joint sealing===
Also called joint and crack repair, this method's purpose is to minimize infiltration of surface water and incompressible material into the joint system. Joint sealants are also used to reduce dowel bar corrosion in concrete pavement restoration techniques. Successful resealing consists of old sealant removal, shaping and cleaning the reservoir, installing the backer rod and installing the sealant. Sawing, manual removal, plowing and cutting are methods used to remove the old sealant. Saws are used to shape the reservoir. When cleaning the reservoir, no dust, [[dirt]] or traces of old sealant should remain. Thus, it is recommended to water wash, sand-blast and then air blow to remove any sand, dirt or dust. The backer rod installation requires a double-wheeled, steel roller to insert the rod to the desired depth. After inserting the backer rod, the sealant is placed into the joint. There are various materials to choose for this method including hot pour bituminous liquid, silicone and preformed compression seals.<ref name="igga" /><ref>{{cite web |url=http://www.igga.net/File/Minimize-Wheel-Slap-Keep-Your-Joints-Narrow-_2004.pdf |title=Minimize Wheel-Slap: Keep Your Joints Narrow |access-date=2010-01-06 |url-status=dead |archive-url=https://web.archive.org/web/20110723154515/http://www.igga.net/File/Minimize-Wheel-Slap-Keep-Your-Joints-Narrow-_2004.pdf |archive-date=2011-07-23 }} IGGA</ref><ref>How States Preserve Concrete Pavements: CPR pays off in extra pavement life.
