King William Road is 2.2 km long, commences about 2 km to the south of Adelaide's central business district and passes through the suburbs of Unley, Wayville, Goodwood, Hyde Park and Unley Park. The northern third passes through a mixed commercial / residential area, the central third through a shopping...

The National Association of Australian State Road Authorities (NAASRA) has recently published the Guide to the Structural Design of Road Pavements which supersedes the Interim Guide to Pavement Thickness Design published in 1979. The new guide incorporates a mechanistic design procedure for flexible pavements that represents a quantum leap forward...

The Brisbane City Council is responsible for maintaining approximately 5000 km of road. A Pavement Management System was developed in 1977 to formulate policy on the effective funding for the maintenance and rehabilitation of road pavements. Through this system all streets are visually assessed and classified with regard to surface...

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...

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...

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...

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...

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...

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...
