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
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
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
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
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...
ASCP2021 6th Concrete Pavements (e)Conference – Proceedings (with video recordings)
Outline 2020 tested our flexural capacity and at times strained our mental tensile strength to 85% yield. To maintain tradition, ASCP has worked hard to develop a unique line-up of papers and delivery format for its 6th Concrete Pavements Conference which was delivered in August 2021. Like previous biennial conferences,...

A Study of Ground Performance for Rigid Pavement Design: Pacific Highway Upgrade at the Warrell Creek Floodplain
The alignment of the proposed Pacific Highway upgrade between Warrell Creek to Nambucca Heads traverses five (5) major floodplain areas underlain by deep soft alluvium sediments. The low bearing capacity and high compressibility of foundation soils were found to attract significant ground settlements, with differential settlements to adversely impact the...
CRCP Rehabilitation Design to Rectify Mine Subsidence Damage on M1 Motorway
This paper details the concrete reinforced concrete pavement rehabilitation design required to rectify the damage due mine subsidence on the M1 Motorway north of Cockle Creek Killingworth. Concrete pavement settlements had been monitored from July 2003 to November 2010 at a series of locations along the northbound and southbound carriageways....
