Australian concrete pavements are relatively unique in the world with the majority consisting of unreinforced jointed plain concrete. Joints are sealed to prevent ingress of incompressible particles that can cause premature failure. Over the past decade one of the most substantial short-term maintenance costs for plain concrete pavements has been...

Roller Compacted Concrete (RCC) is a no slump concrete that is placed by an asphalt paver and compacted with vibratory rollers similar to asphalt pavement construction. RCC has long history of good performance as a pavement for ports, container yards, and manufacturing plants. This paper will summarize a recent survey...

Steel fibre reinforced concrete has been widely used for pavement construction. The conventional pavement design methodology and that of adopted by the Australian pavement design guidelines are generally based on elastic theory. The addition of steel fibres to concrete enhances the post crack tensile strength and provides significant ductility. Consequently,...

Road Authorities commonly require detailed 40 year design traffic loading (DTL) estimates and concrete pavement thickness design calculations. The purpose of this paper is to draw attention and to demonstrate that detailed concrete pavement design in accordance with the Austroads Pavement Design Guide and RMS Supplement can be a time...

There are a large number of concrete pavements in Australia, with many dating back to the first half of the 20th century. These concrete pavements are still in use today, and since the time these pavements were constructed, we have seen an evolution in traffic volumes and the size of...

The concrete paving of the North-South Corridor, Norther Connector in South Australia was as much a political challenge as it was a logistical and technical one. George Panagopoulos, DPTI Project Manager, outlines the unique political journey to achieving the Project's successful inception and completion.

During the Northern Connector tender, concrete pavements was discussed early as an option. Our concrete pavement solution became Lendlease’s primary submission with flexible pavement as an alternative as it provided increased local content and introduced new skills for the region. Following contract award, immediate planning for detailed jointing design, raw...

Keynote presentation by Transport for NSW's Director of Strategic Investments covering; Sources of road funding 2019-20 budget funding for infrastructure Current significant transport projects Funder decision making framework Value for money assessment and economics Hypothetical motorway upgrade – asphalt vs concrete The life cycle cost conundrum

The M4 Widening project comprised the first stage in the delivery of WestConnex. It involved the widening and upgrading of approximately 7.5 kilometres of the M4 Motorway (M4) between Pitt Street, Parramatta and Homebush Bay Drive, Homebush. The project was opened to traffic in July 2017, in line with the...

Bonded concrete overlays on asphalt (BCOA), historically known as whitetoppings, are growing in popularity as an option for rehabilitating distressed asphalt pavements. Despite their application over the past several decades, the existence of performance models for this type of pavement are rare. It was the objective of this study to...

This presentation comprehensively reviews the Kariong to Somersby project. This project is one of three major M1 Upgrades with notable features including; Dual PCP, 33 years in service, 70 km north of Sydney, AADT over 60,000 and growing. Importantly, this is a capacity driven upgrade (widening not a rehabilitation). Key...

The advent of the new generation of volumetric concrete mixers in conjunction with the availability of calcium sulfoaluminate cements has transformed concrete pavement maintenance practice around the world and especially in the United States, Canada and South Africa and in NSW where there is a history of 8 years’ experience...
