Grated Drain by the Slip Form Method

Highways Members Only

Over the past 12 years JK Williams Contracting Pty Ltd (JKW) have been slip forming kerbs and guttering, F type barriers, CRCP and residential concrete path paving across Greater Sydney developments. Over the period, we became very aware of a demand for lengthy ‘ACO’ style grated drains, something which emerged...

Impact of GGBFS Cement on the Interfacial Transition Zone and Influences on Flexural Strength of CRCP Concrete

Highways Members Only

With an increased focus on sustainability of concrete in commercial and infrastructure projects, the use of alternative cementitious sources is increasing. At the same time the availability of flyash in Eastern Australia is becoming less certain and secure in terms of both quality and future quantity. Transport for NSW specification...

A Review of International Practices for Design of Rigid Pavements for International Container Terminals

Intermodals/Ports Members Only

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...

2021 A Subbase Odyssey

Highways Members Only

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...

Specifying Concrete Pavement for Local Government

Highways Members Only

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...

32mm Aggregate Trial at Oxley to Kundabung Pacific Highway Upgrade

Highways Members Only

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...

Investigation of Crack Width Development in CRCP

Highways Members Only

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...

Review of the Erosion Criteria for Bound Subbases in the Australian Rigid Pavement Design Procedure

Highways Members Only

The current Australian rigid road pavement design procedure considers both structural concrete slab fatigue and subbase erosion. The erosion component was introduced in the 1992 edition of the Austroads pavement design guide as nomographs and incorporated as algorithms in the 2004 edition of the guide. The erosion distress criteria were...
