Until the last few years the main use of pavement rehabilitation by recycling the existing pavement by cement stabilisation had been in urban roads administered by Local Government. The existing pavement thicknesses and therefore the depths of pavement recycling in these applications are typically 150—200 mm. Using similar procedures the...

Continuously reinforced concrete (CRC) pavements have the feature that the longitudinal reinforcement is continuous for the entire length of the pavement. Other than end-of day construction joints there are no transverse joints in CRC pavements. By balancing concrete properties, thickness and the amount of reinforcement, fine transverse cracks are developed...

When the owners of properties fronting Roma Parade in the Shire of Sherbrooke, Victoria requested construction of their private road, it posed real problems for the Shire’s designers. Roma Parade is very steep havi ng a 67 metre fall in level over its 248 metres length. Their final design included...

The contractor, Seovic Holdings, using a Miller M9000 slipform paver and supported by the resources of Farley and Lewers (Old) Limited achieved a...

As part of the planning and design of a road pavement it is allocated a ’design-life’. This is the period over which traffic loads are estimated for use in structural design. Usually expressed in years the typical range of design lives is 20—40 years. Concrete road pavements are frequently designed...
