Maintenance

The Warringah Freeway (FI) extending north from the Sydney Harbour Bridge was commissioned in 1968. It was the first major length of urban concrete freeway pavement in Australia. The pavement, including shoulders, is reinforced concrete with a total length equivalent to 42 km of a two-lane road. Built under a...

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 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,...

Balmain Road is one of the oldest roads in the Municipality of Leichhardt, about 5 km west of the Central Business District of Sydney. The road provides an important link between Parramatta Road and Victoria Road which are two major arterials. This year, the road was scheduled for reconstruction. After...

With an eye to future rehabilitation solutions, John Hodgkinson re-visited a CRCP overlay constructed on the Hume Highway, just north of Holbrook, in 1992. A significant milestone was reached in June 2021 as the first BCSA Rapid Set Concrete slab celebrated its 10th Birthday in Australia at Sydney International Airport. Since this...

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...

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,...

Sydney has a very large network of State and Local Government concrete roads built from the mid 1920s to the 1950s.  There is an increasing need for slab replacements, but with worksite access typically limited to a single night shift.  Using CSA rapid set cement, there are now 12 years...

Luc Ramalinga presents on Airport Infrastructure - From History to the Future. Objective of this Presentation: - Give an insight of how a client approaches airport pavement management - The History of Airport Pavements - The Impact and Opportunities of COVID-19 - Future Research Opportunities

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....
