Performance Of Concrete Pavements On Major Nsw Roads (Nov 1990)

In recent years there has been a significant increase in the construction of concrete (rigid) pavements in NSW on both major highways and urban, municipal networks. Concrete roads have been constructed in configurations varying from two—lane carriageways to six-lane, dual-carriageway formations. Three major, heavily trafficked roads on which concrete pavements have been constructed in NSW are SH2 Hume Highway (Sydney—Albury), F3 Freeway (Sydney—Newcas1le) and SH3 Federal Highway (Goulburn—Canberra). As of 1989 a total of about 640 1rafficked lane km within 24 major paving contracts have been completed on these roads for the Roads and Traffic Authority (RTA) of New South Wales. The general performance of the concrete pavement inventory on these three roads and particular aspects of the maintenance strategy and rehabilitation methods for them are outlined in this Road Note.
