RCC Pavements in Tasmania, Australiaby David M. Brett, Avoca Transport Co, Hobart, Australia,
Abstract: Over 60,000 m**2 of high strength Roller Compacted Concrete (RCC) pavement has been completed in Tasmania, Australia, since December 1986. Projects have ranged from footpaths and small industrial hardstands to haul roads for mining operations and a section of public highway. Several aggregate types, gradings and jointing systems have been used. The pavement RCC mix has included a proportion of condensed silica fume (CSF) which has been found to have a significant effect on pavement strength. The RCC mix design techniques, construction details, quality control testing and pavement performance are discussed. Costing on various projects is presented.
