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...

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...

Balmain Road is one of the oldest roads in the Municipality of Leichhardt, about 5 km west of the Central Business District of Sydney.

Safety on the public road is a matter of concern to the whole community. Fast moving opposing streams of traffic are often separated only by air and paint and the potential for collisions is high. Many campaigns are conducted to improve driver education and performance; regulations require an increasing number...

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,...

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...

Roundabouts are being constructed to provide improved traffic facilities at a variety of intersections ranging from local collector/distributor roads to arterial roads and highways. They increase overall community amenity by reducing traffic speeds and accidents — by limiting the number of conflict points the potential for collisions is reduced and...

The Brisbane City Council is responsible for maintaining approximately 5000 km of road. A Pavement Management System was developed in 1977 to formulate policy on the effective funding for the maintenance and rehabilitation of road pavements. Through this system all streets are visually assessed and classified with regard to surface...
