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...
Major Concrete Pavement Rehabilitation by Rapid Slab Replacement. Pacific Motorway Queensland
Rehabilitation of concrete road pavements by rapid slab replacement in single shifts has been established in Australia for ten years. Until recently it has been used for spot replacement of slabs in both road and airport applications. In South East Queensland in 2013, a program over a series of 22...
Low Noise Diamond Grinding Pacific Highway Trial
A Low Noise Diamond Grinding (LNDG) Trial was conducted across three sites on the Pacific Highway Upgrade, Nambucca Heads to Urunga section. This presentation outline the basics around LNDG, criteria for the trial, environmental considerations, analysis of results of the trial, summary of the outcomes, considerations and recommendations for future...
Developments in Rapid Set Lean Concrete Subbase
The technology and practice for single shift high strength concrete base replacement, mainly at night, using rapid set concrete has been established in Australia for ten years. Since 2017 this technology has now been adapted and extended to developing a rapid set lean concrete and related registered mixes. This has...
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...
