Neoprene Joint Seals for Concrete Pavements
Australian concrete pavements are relatively unique in the world with the majority consisting of unreinforced jointed plain concrete. Joints are sealed to prevent ingress of incompressible particles that can cause premature failure. Over the past decade one of the most substantial short-term maintenance costs for plain concrete pavements has been...
Fracturing Concrete Pavement Technology
There are a large number of concrete pavements in Australia, with many dating back to the first half of the 20th century. These concrete pavements are still in use today, and since the time these pavements were constructed, we have seen an evolution in traffic volumes and the size of...
Construction – The Devil’s in the Detailed Design
Rigid pavement RFIs (request for information) and NCRs (nonconformance report) are an ongoing battle between contractors and designers. This is the frontline of construction phase services (CPS) and when not managed correctly, can lead to tension between contractors and designers, which can lead to breakdown of communications and affect construction...
Recent Advances and Uses of Roller Compacted Concrete for Pavement Construction in the United States
Roller Compacted Concrete (RCC) is a no slump concrete that is placed by an asphalt paver and compacted with vibratory rollers similar to asphalt pavement construction. RCC has long history of good performance as a pavement for ports, container yards, and manufacturing plants. This paper will summarize a recent survey...
Funder Decision-Making and Review of Pavement Types for Major Projects
Keynote presentation by Transport for NSW's Director of Strategic Investments covering; Sources of road funding 2019-20 budget funding for infrastructure Current significant transport projects Funder decision making framework Value for money assessment and economics Hypothetical motorway upgrade – asphalt vs concrete The life cycle cost conundrum
Construction of the M4 Widening, WestConnex Stage 1A
The M4 Widening project comprised the first stage in the delivery of WestConnex. It involved the widening and upgrading of approximately 7.5 kilometres of the M4 Motorway (M4) between Pitt Street, Parramatta and Homebush Bay Drive, Homebush. The project was opened to traffic in July 2017, in line with the...
Development of Performance Curves for Thin Bonded Concrete Overlays on Asphalt in Minnesota24
Bonded concrete overlays on asphalt (BCOA), historically known as whitetoppings, are growing in popularity as an option for rehabilitating distressed asphalt pavements. Despite their application over the past several decades, the existence of performance models for this type of pavement are rare. It was the objective of this study to...
M1 Upgrade – Kariong To Somersby Project Lessons Learning
This presentation comprehensively reviews the Kariong to Somersby project. This project is one of three major M1 Upgrades with notable features including; Dual PCP, 33 years in service, 70 km north of Sydney, AADT over 60,000 and growing. Importantly, this is a capacity driven upgrade (widening not a rehabilitation). Key...
Use of Fast Set Concrete For Concrete Pavement Maintenance Work
The advent of the new generation of volumetric concrete mixers in conjunction with the availability of calcium sulfoaluminate cements has transformed concrete pavement maintenance practice around the world and especially in the United States, Canada and South Africa and in NSW where there is a history of 8 years’ experience...
