Road traffic noise affects approximately 8 million people in Australia with 2 million seriously affected, far more than from other forms of transportation. As the principal source of road noise is from the tyre/pavement interface and, given that concrete pavements are preferred by many road authorities due to its hard...

Portland cement has undergone much change in recent decades to cater for rapid construction cycles, longer design life and environmental pressure. Increased fineness, the advent of Portland blended cements incorporating one or more supplementary cementitious materials (SCMs), and reduced clinker content via mineral addition have been the key technological solutions...

Current and future eras are seeing an operational environment where road occupancy for pavement maintenance or repairs will be severely restricted under conditions of maximising availability for service traffic and access to roadside properties. A key driving force for concrete pavement slab replacement, where required, is the need to use...

Roller Compacted Concrete (RCC) is a no slump concrete that is placed by a high density 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 summarise a recent...

There are few methodologies for the structural pavement design of port and external heavy duty pavements. Traditionally, the pavement design of heavy-duty pavements has been considered a high risk area due to the high proportion of failures and their cost implications (operational and repair). Due to the lack of specific...

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...
