Joint sealants are indispensable components of Jointed Plain Concrete Pavements (JPCP), the standard construction method in Germany. The joint filling system is subjected to various loads during their service life, which in practice lead to a regular renewal of the sealing after about 7 -10 years. Nevertheless, it must be...
Use of glass fibre reinforced polymer bars in concrete pavements
The use of glass fibre reinforced polymer (GFRP) bars as an alternative to steel reinforcement has considerably increased over the past decade. Design-related information is now available and can be adapted into the Australian design and construction practice. The results of technological research and field implementation in concrete pavements carried...
More Durable & Thinner Steel Fibre Concrete Pavements
Steel fibre reinforced concrete has been widely used for pavement construction. The conventional pavement design methodology and that of adopted by the Australian pavement design guidelines are generally based on elastic theory. The addition of steel fibres to concrete enhances the post crack tensile strength and provides significant ductility. Consequently,...
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...
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...
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...

The important role materials play in concrete pavement design, performance, and service life
The materials that make up concrete have a direct influence on the decisions made during pavement design and construction, as well as the performance of the pavement in service. What happens when material performance varies from what was considered at design stage? What if we need to change construction methods...
Overview of light rail track slab design
Recently Aurecon have developed the design on several urban light rail projects, with a notable example being that recently opened in Newcastle. With several projects currently in development and tender phases, and the likelihood of further stages of light rail expansion, it is important to understand the options available for...
Preparation for Concrete Pavements
This presentation covers key topics in the adequate construction preparation works for successful concrete pavements including; Subgrade Preparation Mix Design Mix Consistency String line Setup Paver Operation Motivated Trained Team Tips and Tricks
RMS Standard Concrete Construction Drawings: Latest Revisions
This presentation by the Senior Pavements Manager, Engineering Services Branch, Roads and Maritime Services, informs the industry of revisions to the RMS Standard Concrete Construction Drawings. Revisions in this presentation outline changes new at the time of presenting May 2016.
New Developments in Concrete Mix Design
This forum addressed both concrete road pavements & concrete industrial pavements. Presentations made addressed concrete mix designs, design & construction aspects, as well as current information about diamond grinding of concrete road pavements in Australia. New developments in concrete mix design: • Sands have become finer with a gap between...
