Construction, Contractor Capability & Innovation: How can we achieve these outcomes in a risk adverse concrete pavements was another successful (ONLINE) event. With over 100 attendees registered and almost 90 joining the event - this forum brought together a range of key experts within the concrete pavement supply chain where each...

Salamanca Place in Hobart is a unique historic area dating from the 1830s. Georgian sandstone warehouse buildings flank a 24-m-wide roadway built over a reclaimed area originally used by the whaling fleet and shipping lines. The refurbished warehouses now function as professional offices, restaurants, a foundation covering most facets of...

"Roller Compacted Concrete (RCC) is a dry highstrength concrete pavement material which is compacted by external rolling rather than internal vibration. When placed, RCC must be dry enough to support the weight and passage of rollers so that it does not shear, but moist enough during mixing to allow adequate...

Salamanca Place Hobart is a unique historic area dating from the 1830s, its Georgian sandstone buildings flanking a 24-metre-wide roadway built over an old wharf area originally used by the whaling fleet and shipping lines. A row of plane trees now totally define the road beyond which are the Marine...

The National Association of Australian State Road Authorities (NAASRA) has recently published the Guide to the Structural Design of Road Pavements which supersedes the Interim Guide to Pavement Thickness Design published in 1979. The new guide incorporates a mechanistic design procedure for flexible pavements that represents a quantum leap forward...

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.

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...

The Warringah Freeway (FI) extending north from the Sydney Harbour Bridge was commissioned in 1968. It was the first major length of urban concrete freeway pavement in Australia. The pavement, including shoulders, is reinforced concrete with a total length equivalent to 42 km of a two-lane road. Built under a...

Much of the mechanism to minimise the environmental impact of new, and upgrading of existing, roads is described in environmental impact statements (FIS). Recently, the community has played an important role in the preparation of EISs by assessing the potential impact and benefits derived from such statements Prepared by engineers....

Many Local Government authorities in Australia are finding themselves in the position where roads constructed many years ago are now showing signs of distress. This can be due to a deterioration in the riding surface, a loss pf structural capacity in the pavement itself or, as is often the case,...

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...

Pavement performance audits have also assisted engineers to analyse vast amounts of data relating to the performance of various traffickable roads in the municipality. Assessing different rehabilitation or reconstruction strategies requires an understanding of the costs and longevity of different pavement types and treatments. Since rigid pavements outlast flexible pavements,...
