What Happens When the Fly Ash Runs Out? Bruce Perry1 1 National Customer Technical Support Manager, Cement Australia ABSTRACT For many years, the replacement of cement with fly ash in pavement concrete mixes has been mandated by infrastructure asset owners. In NSW, R82 requires a minimum 40% replacement level whereas...

ASCP 7TH CONCRETE PAVEMENTS CONFERENCE: PAVING THE FUTURE (TECHNICAL PROGRAM)
FROM THE PRESIDENT On behalf of the Conference Steering Committee, it is our pleasure to invite your organisation to participate in the 7th ASCP Concrete Pavements Conference. This event will be held at Novotel Northbeach in Wollongong, NSW -- kicking off Sunday 22nd (welcome reception) with two (2) days of...
Concrete Pavement Preservation: Maintenance and Rectification Techniques (Pavement Note 004)
Over the service life of a heavy-duty concrete pavement, concrete pavements will gradually degrade in ride quality and the slab surface may lose some of its initial texture, leading to a reduction in skid resistance and/or increased risk of aquaplaning. This Pavement Note summarises the types and causes of occasional...
ASCP Forum – Innovation, Sustainability & Low Carbon Concretes – Tuesday 31st May 2022
Innovation, Sustainability, Low Carbon Concretes: How can we achieve in Pavements – was the hotly anticipated topic of our May 2022 Forum. The Australian cement and concrete sector has a long history of reducing its CO2 emissions having delivered a 25 percent reduction since 2000 [VDZ 2022] being a critical...
Concrete Segmental Pavements (May 1993)
Salamanca Place in Hobart is a unique historic area dating from the 1830s. Georgian sandstone warehouse buildings flank a 24-m-wide roadway built over a reclaimed area originally used by the whaling fleet and shipping lines. The refurbished warehouses now function as professional offices, restaurants, a foundation covering most facets of...
Roller Compacted Concrete Pavements (Jun 1989)
"Roller Compacted Concrete (RCC) is a dry highstrength concrete pavement material which is compacted by external rolling rather than internal vibration. When placed, RCC must be dry enough to support the weight and passage of rollers so that it does not shear, but moist enough during mixing to allow adequate...
Bankstown City Council A Review Of 10 Years Of Recycling Streets By Cement Stabilisation (Sep 1981)
Many Local Government authorities in Australia are finding themselves in the position where roads constructed many years ago are now showing signs of distress. This can be due to a deterioration in the riding surface, a loss pf structural capacity in the pavement itself or, as is often the case,...
Brisbane City Council Process Approach To Insitu Cement Stabilisation As A Rehabilitation Method For Failed Pavements (Aug 1990)
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...
Pavement Asset Management (Aug 1995)
Pavement performance audits have also assisted engineers to analyse vast amounts of data relating to the performance of various traffickable roads in the municipality. Assessing different rehabilitation or reconstruction strategies requires an understanding of the costs and longevity of different pavement types and treatments. Since rigid pavements outlast flexible pavements,...
Stabilisation Plant Operating In Australia (Nov 1981)
Stabilisation, already widely used in road pavements in Australia, is being increasingly specified by engineers in three general areas: (a) To improve the engineering properties of sub- grade materials. (b) To modify or strengthen locally available materials which are often of a marginal quality in a situation of diminishing availability...
