This paper details the concrete reinforced concrete pavement rehabilitation design required to rectify the damage due mine subsidence on the M1 Motorway north of Cockle Creek Killingworth. Concrete pavement settlements had been monitored from July 2003 to November 2010 at a series of locations along the northbound and southbound carriageways....

SRAs have been used in concrete in Australia since their introduction into the marketplace in the mid1990s. However, its recent application in a major road project in NSW has generated interest from Government bodies, engineers and contractors within this sector of the construction industry. The author therefore wishes to discuss...

Concrete pavement joints are required to be sealed to prevent the ingress of debris, mainly incompressible and water. In the year of 2012, there are a number of reports of pavement joint sealants losing adhesion within the first 5 years of service and eventually being mostly depressed under the wheel...

Conventional diamond grinding has been used in Australia since 2010. The purpose of diamond grinding is to improve ride quality and shape, reinstate service texture and reinstate skid resistance. This presentation reports on trials of low noise diamond grinding in NSW, Australia with analysis of performance monitoring results and comparison...

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...
