The Housing Commission of New South Wales has developed engineering designs and standards for urban subdivision over a period of more than 30 years. The Commission has developed practical and economical road designs as a result of this experience. The larger-scale subdivisions include several types of roads, ranging from quite...

On 16th December 1982 the Hon. Neville Wran, Premier of New South Wales, opened two new sections of the F4 Western Freeway near Sydney. The comibined length of almost 9 km is made up of 5.8 km between Strathfield and Silverwater, and 3 km between Parramatta and Mays Hill Figure...

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...

During recent construction on a deviation of the Pacific Highway in South East Oueensland an Australian concrete road paving record of 1 km per day was established. 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...

Throughout Australia, concrete safety barriers are being used to improve the safety of existing roads and to provide a built-in safety feature in new roadways. When used as med ian barriers, their most common ro ]e, they minimise the risk of head-on collisions, the type of accident which accounts for...

Tumblong Devia1ion, located approximately midway between Sydney and Melbourne, will provide 17 km of high—standard, dual carriageway highway linking the township of Tumblong and the intersection of the Hume Highway and 1he Snowy Mountains Highway. A significant illus1rat ion of activities within the Aus1ralian Bicentennial Road Development Programme funded by...

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...

The Adelaide City Council has recently made extensive use of concrete interlocking block paving in several projects. Landscape design principles were applied in the improvement of several inner-city, largely-residential streets where the aims were to improve their appearance and to make them safer for pedestrians. The two major projects were...

Until recently; the most common method of concrete pavement construction in Local-Government areas utilised steel or timber sideforms, and manually hauled vibrating screeds. This method continues to be ideal for many projects. Slipform road construction was introduced to Australia in 1979, but until 1983 its use was limited to major...

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.
