This Forum ASCP regularly holds technical forums in Brisbane on different aspects related to concrete pavements. In this forum, three presenters from the industry will cover material specification, innovative materals, and design methods using geosynthetics

KEY POINTS FOR DESIGNER AND CONTRACTOR • What is practically achievable? • Cost increase • Options to reduce/control cracking :  Be aware of details that provide a restraint  Reinforcement?  Joint width/ Number of Joints  Consider “Chequerboard” board pours instead of long strip  Aliphatic alcohol before...

ABOUT THIS FORUM The modern concrete road pavement produces a high quality, heavy duty asset at low initial cost, with low maintenance requirements, and with high performance properties. There are many major concrete road pavements in NSW which are now reaching their design lives and which have demonstrated high performance...

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...
