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...

Throughout Australia, concrete safety barriers are being used to improve the safety of existing roads and to provide a built-in safety feature in new roadways. When used as med ian barriers, their most common ro ]e, they minimise the risk of head-on collisions, the type of accident which accounts for...

When the owners of properties fronting Roma Parade in the Shire of Sherbrooke, Victoria requested construction of their private road, it posed real problems for the Shire’s designers. Roma Parade is very steep havi ng a 67 metre fall in level over its 248 metres length. Their final design included...

The Housing Commission of New South Wales has developed engineering designs and standards for urban subdivision over a period of more than 30 years. The Commission has developed practical and economical road designs as a result of this experience. The larger-scale subdivisions include several types of roads, ranging from quite...

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...

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...

With an eye to future rehabilitation solutions, John Hodgkinson re-visited a CRCP overlay constructed on the Hume Highway, just north of Holbrook, in 1992. A significant milestone was reached in June 2021 as the first BCSA Rapid Set Concrete slab celebrated its 10th Birthday in Australia at Sydney International Airport. Since this...

Recent field observations on several newly constructed Continuously Reinforced Concrete Pavements (CRCP) in Belgium have indicated that the crack pattern is characterized as low mean crack spacing (approximately 1.0 m after 2 years in-service) along with a high percentage of clusters of closely spaced cracks. Besides, field surveys also indicate...

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...

In addition to advances in materials and construction equipment there is a continuing need to ensure adequate skills are available within paving crews. Since 2006 concrete pavement crews and their supervisors in Australia have been required to undertake a mandatory one-day course. Known in industry as the “Grey Card” course...

Maturity testing of concrete, and applications for concrete pavements will be explored by Sabrina Garber from Transtec (USA). On a recent motorway project in Sydney roller compacted concrete was adopted as a working platform for pavement construction on local government roads. The successes and lessons learnt will be explored by...

The Carbon nanotubes (CNTs) in a liquid additive when used in the design and construction of concrete, serve as nucleation sites during cement hydration to help create a denser, cement paste composition. The result is improved durability and strength. CNT technology remains ‘young’ within Australia; various laboratory and field trials...
