Use of Fast Set Concrete For Concrete Pavement Maintenance Work

Airports, Highways, Industrial, Intermodals/Ports, Trackslabs Members Only

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...

Recent Advances and Uses of Roller Compacted Concrete for Pavement Construction in the United States

Airports, Highways, Industrial, Intermodals/Ports, Local Government, Trackslabs Members Only

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...

Characterization of joint sealants through an innovative test procedure

Airports, Highways, Industrial, Intermodals/Ports, Trackslabs Members Only

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...

More Durable & Thinner Steel Fibre Concrete Pavements

Airports, Highways, Industrial, Intermodals/Ports, Local Government, Trackslabs Members Only

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

Airports, Highways, Industrial, Intermodals/Ports, Trackslabs Members Only

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...

The important role materials play in concrete pavement design, performance, and service life

Airports, Highways, Industrial, Intermodals/Ports, Trackslabs Members Only

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...

Investigation on the effect of low carbon, low shrinkage, high flexural strength envisia® concrete on industrial floor and pavement application

Industrial, Intermodals/Ports Members Only

The key structural element in most industrial enterprises is the concrete floor slab. The aim of floor design is to select the most economical thickness while considering sufficient reinforcement to control the amount and size of cracks to a level consistent with the intended use of the floor. However, one...
