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. The work has been located within sections of the Highway from Bulahdelah to the Port Macauarie area. An integral...

Concrete is being increasingly used in the Sydney area to provide a sub-base for flexible road pavements. Typically, the pavement comprises 150 mm of plain concrete sub-base beneath a conventional roadbase and a surfacing of asphaltic concrete. Figure 2 shows the general form of pavement construction. The concrete sub-base provides...

SinceJ982, activities under the Australian Bicentennial Road Development Program (ABRD), in conjunction with works under other Commonwealth and Stale funding arrangements have become highly visible in up- grading the Australian road system to a high standard. In New South Wales and elsewhere concrete roads in varying configurations up to six-lane,...

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...

Balmain Road is one of the oldest roads in the Municipality of Leichhardt, about 5 km west of the Central Business District of Sydney. The road provides an important link between Parramatta Road and Victoria Road which are two major arterials. This year, the road was scheduled for reconstruction. After...

In recent years there has been increasing usage of cement-stabilisation techniques to rehabilitate or re- cycle existing granular road pavements, providing a major service-lite extension for them at a cost much lower than that of reconstruction. This technique has now been successfully extended to include forestry roads. Following a successful...

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....
