Construction

Controlling cracking to acceptable levels in concrete structures requires accurate detailing and good construction practices. This is more prevalent in ground supported slabs that are typically detailed to avoid cracks occurring under service stresses. Detailing the slab to avoid these cracks puts a number of limitations on the floor design...

A new methodology has been developed to design the concrete slab thickness by optimizing the slab size given the geometry of the truck axles, the design is based on an unbonded system with either granular, HMA, Stabilized or Concrete Base. The key principle of the design method is to configure...

This paper summarises the results of a preliminary trial to validate a localised application of controlled induced cracking (active crack control, ACC) in continuously reinforced concrete pavements (CRCP) with local construction practices and conditions. ACC is currently being investigated in Europe. The work sought to gauge the merit of developing...

In rigid (concrete) pavement design and construction the word “terminal” is used to describe the termination of a concrete pavement abutting other “structures” such as a flexible pavement, a bridge abutment, or another concrete pavement where structural continuity is impractical or undesirable. A discontinuity in grade caused by the differential...

Modern concrete pavements are based on sophisticated blends of cements, often containing SCM, graded nonreactive aggregates and various admixtures, all of which are aimed at producing the most durable pavement possible. Placement techniques also incorporate the use of various curing compounds, which again are aimed at producing durable concrete. However,...

Much interest has been shown in improving the sustainable performance of concrete. The use of cement replacement materials and geopolymer concrete offers benefits in terms of reduced carbon footprint and enhanced properties. This paper reviews the properties of geopolymer concrete and concrete with high levels of cement replacement materials relevant...

The quality of the input of fine and coarse aggregates for concrete has an influence on the quality and consistency of the new concrete, and this is particularly applicable when recycled concrete aggregates (RCA) are incorporated in the concrete. The overseas literature indicates that where substitutions do not exceed 20%,...

Slipform construction of concrete road pavements began in the USA in the late 1940s. It was introduced in Australia in 1978/79 and is now the preferred form of construction and used wherever practicable. Australia’s first slipformed concrete pavement, Foreshore Road at Botany Bay in Sydney, about 4km in length with...

The fundamental goal of any pavement design and construction project is to provide a pavement system that will survive the predicted traffic and environment for the pavement design life. Structural design is primarily considered as the way to meet that goal. Concrete mixtures and construction practices are generally assumed to...
