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...

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...

Rehabilitation of concrete road pavements by rapid slab replacement in single shifts has been established in Australia for ten years. Until recently it has been used for spot replacement of slabs in both road and airport applications. In South East Queensland in 2013, a program over a series of 22...

A Low Noise Diamond Grinding (LNDG) Trial was conducted across three sites on the Pacific Highway Upgrade, Nambucca Heads to Urunga section. This presentation outline the basics around LNDG, criteria for the trial, environmental considerations, analysis of results of the trial, summary of the outcomes, considerations and recommendations for future...

The technology and practice for single shift high strength concrete base replacement, mainly at night, using rapid set concrete has been established in Australia for ten years. Since 2017 this technology has now been adapted and extended to developing a rapid set lean concrete and related registered mixes. This has...
