Construction

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.

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...

About 2700 delegates attended the five-day Congress which consisted of plenary sessions, committee reports and technical tours.

Many campaigns are conducted to improve driver education and performance; regulations require an increasing number...

Signfcant changes in the costs and availability of key resources, which began to occur in the 1970s and are continuing in the 1980s, together with reassessments of the effects of traffic loads, particularly heavy traffic, are seeing reviews of the types of pavements and their design by road authorities in...

A significant illus1rat ion of activities within the Aus1ralian Bicentennial Road Development Programme funded by...

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...

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.
