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...

The Australian Society for Concrete Pavements (ASCP) exists to advance knowledge, technology, and best practice in concrete pavement design, construction, and maintenance across Australia. We are committed to fostering a collaborative, innovative, and technically informed community that promotes excellence in concrete pavements through education, industry engagement, and continuous improvement.  The...

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...

The traffic volume on German motorways increased steadily and this trend is expected to continue in the future. To guarantee mobility in the future and reduce the national economic consequential costs, road construction with a maximum service life and a minimum of necessary maintenance are needed. Rigid road pavements with...

This paper focuses on the analysis of pavement sensor data collected from the 32mm aggregate trial at Oxley to Kundabung Pacific Highway Upgrade project. This trial was intended to establish the concrete mix design parameters, verify the paving ability of the mix and to observe the environmental loading behaviour of...

This presentation will provide an overview of the AUS-SPEC information, tools, technical specification templates, specifications framework and processes to document requirements for various asset life cycle activities. It will also demonstrate the use of the system to create contract documentation for the design, construction, and maintenance of local government infrastructure...

The subbase layer has a critical role in the design of concrete pavements. Australia is unique in its routine application of a lean mix concrete subbase layer to much of the heavy-duty concrete pavement highway network, the result of which is a reluctance to adopt any alternative (“why fix what...

Whilst the practice of pavement thickness design for heavy duty rigid pavements, such as highways, is well established in Europe, the USA and Australia, agreed methodologies for the thickness design of extremely heavy-duty pavements such as those in intermodal container terminals/ports (ICT) is not commonplace. ICT facilities present a number...
