Design

In recent years there has been a significant increase in the construction of concrete (rigid) pavements in NSW on both major highways and urban, municipal networks. Concrete roads have been constructed in configurations varying from two—lane carriageways to six-lane, dual-carriageway formations. Three major, heavily trafficked roads on which concrete pavements...

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...

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 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...

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....

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...

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.

Construction of a major concrete road is nearing completion at South Melbourne, for the Country Roads Board, Victoria. The total area of pavement is nearly 70,000 square metres, equivalent to 19 lane Kilometer of roadway. The road forms the southern and northern approaches to the new bridge over the Yarra...

About 2700 delegates attended the five-day Congress which consisted of plenary sessions, committee reports and technical tours. The Association’s national infra— structure engineer attended the Congress to assess the relevance of new road technology for Australia. The Congress was organised by PIARC (a more detailed explanation of PIARC can be...

We favour the finish-and-forget concrete pavement where it can be economically justified , said Parramatta Council‘s Chief Engineer, Mr. Fred Smale. Parramatta Council has now been using concrete pavements long enough to know that, in the long term, they save money. Not onIy does Council save on maintenance, but road...

The road transport system is a valuable and essential part of Australia’s infrastructure in which we all have an enormous stake. However, infrastructure is a long- term investment in the future and consequently receives little attention from the public unless something goes wrong or individually, we are affected by delays...

Concrete is used throughout the World every day in countless diverse applications but it is critically important in terms of performance and durability to understand why the mix design and placement need to be appropriately tailored to suit each application. The inimitable Geoff Ayton will explore what it takes to...
