An evaluation of concrete patching in continuously reinforced concrete pavements (CRCP)
located in Illinois was made. Problems in designing and constructing permanent concrete
patches were identified; the costs of patching were estimated; and the performance of typical
patches was evaluated. Illinois has constructed over 4827 two-lane Km (3000 miles) of
CRCP, major portions of which are displaying increasing occurrence of distress that requires
patching. Patches placed in recent years are performing inadequately. A survey of over 800 …

An evaluation of the patching of continuously reinforced concrete pavement (CRCP) in
Illinois has been conducted. The placing of concrete patches to repair localized distressed
areas is an expensive and difficult maintenance operation. Patching demand is increasing
every year due to the aging of the CRCP network. Many aspects of patch design,
construction, costs of materials, equipment and labor, and the associated performance as
currently exists were evaluated. The productivity and costs of the three agencies that …
