BCSA: How HES Concrete compares to OPC - Nouas Al Lug Anchor Design: Mixed Requirements & Standards India's slipform paving experience - B Charmanna

Concrete paving has come a long way since the early 1900s. Whilst high durability pavements were able to be hand-placed 100 years ago, concrete pavements today are produced faster, stronger and more cost efficiently using slipform pavers. We’ve come a long way. Whilst acknowledging that the right pavement is needed...

Combined Reinforcing is fast becoming recognised and proven as the right solution for Container Parks and other Heavy Duty Pavements. In these sorts of pavements the first areas that are prone to breaking down or requiring maintenance under the very high loads that are being applied are often the joints...

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...

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...

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...

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...

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,...

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...

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...

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...
