Pavement performance audits have also assisted engineers to analyse vast amounts of data relating to the performance of various traffickable roads in the municipality. Assessing different rehabilitation or reconstruction strategies requires an understanding of the costs and longevity of different pavement types and treatments. Since rigid pavements outlast flexible pavements,...

Much of the mechanism to minimise the environmental impact of new, and upgrading of existing, roads is described in environmental impact statements (FIS). Recently, the community has played an important role in the preparation of EISs by assessing the potential impact and benefits derived from such statements Prepared by engineers....

The AMCORD URBAN strategy of the 1990s highlights the need to offer greater and more cost-effective choice of urban housing of quality. Along with this need, the study recognised the relevance of infrastructure in terms of physical and social elements.

During the first two weeks of October, in excellent weather, a group of six engineers from four Australian States participated in the C&CAA-arranged study mission to Europe. The mission was established to study the topics of: • concrete tollway operations. • road widening/overlays. • quality systems as applied to construction...

Over the last twenty years municipal planners have gradually accepted the need to plan and implement cycleways for commuter and recreational use. This year saw the release of the new edition of Guide /o Traffic Engineering Practice. Bicycles by AUSTROADS. This technical publication was written with the cooperation of all...

With residential construction on the rise again, both homeowners and developers are seeking greater variety in pavement materials other than that provided by plain concrete or asphalt. To meet this demand, several Australian companies are producing patterned an4 col our ed concrete surface finishes to enhance paved areas in new...

Precast drainage structures play an important role in road d infrastructure renewal and augmentation where minimising the interruption to traffic flow during works is vital. In some rural areas there is not always ready access to skilled concrete workers while restricted site access and speed of construction are major challenges....

The concrete Pavement in Victoria Parade is on the eastbound carriageway between Brunswick and Hoddle Streets in Collingwood, a distance of about 1.25 km. Within the overall alignment of this section of Victoria Parade there is a central reserve containing a tramway, while the westbound carriageway has a flexible pavement...

Over the period October 1990 to December 1992 the Roads and Traffic Au1hority (RTA) in NSW has comDleted the rehabilitation of about half a million sauare metres of the Pacific Highway. The work has been located within sections of the Highway from Bulahdelah to the Port Macauarie area. An integral...

A major reduction in traffic congestion has been achieved in the Melbourne suburb of Heidelberg (11 km north-east of the CBD) with the recent opening of the Bell—Banksia link road. The $40m Federally- funded project reduces heavy through traffic on several local roads and will reduce road transport costs for...

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...

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...
