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...

Stabilisation, already widely used in road pavements in Australia, is being increasingly specified by engineers in three general areas: (a) To improve the engineering properties of sub- grade materials. (b) To modify or strengthen locally available materials which are often of a marginal quality in a situation of diminishing availability...

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...

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...

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...

During 1990 large inland areas of Queensland and New South Wales were devastated by severe floods. Considerable media attention was devoted to the effect of these floods on people and their property. Evacuation, flood-relief oDerations and subseauent rehabilitation of towns damaged by the floods were widely reported. One element of...

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...

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...

The Brisbane City Council operates a Pavement Management System for the identification of the pave- ment needs of the City’s 4400 km of roads. Roads with failed areas exceeding 20 per cent and in need of rehabilitation are identified by this system. One of the rehabilitation methods adopted for roads...

Until the last few years the main use of pavement rehabilitation by recycling the existing pavement by cement stabilisation had been in urban roads administered by Local Government. The existing pavement thicknesses and therefore the depths of pavement recycling in these applications are typically 150—200 mm. Using similar procedures the...
