When

Tuesday, 17 April 2018
5:00 PM - 8:00 PM

Where

TAFE Restaurant
Level 2 - Block C 66 Ernest Street, South Brisbane QLD 4101

Overview

This seminar will look at innovations in concrete pavements that, although perhaps in use in other countries have not yet taken hold in Australia. We will also touch on some practical issues that you may come across in day to day use.

Topics

Permeable Concrete Pavements
John Tuxworth, Managing Director - Built Environment Collective 

Permeable insitu concrete pavements allow air and liquids to pass through the pavement surface. This type of pavement is typically employed to avail of environmental and functional advantages in relation to stormwater management. Water Sensitive Urban Design (WSUD) has been adopted in Australia in order to decrease stormwater flow rates, and also the volume of catchment runoff. Permeable pavements are considered a ‘source control’ option in providing a means of collecting and treating stormwater, and thus minimising the extent and cost of traditional stormwater infrastructure. 
 
Permeable Concrete Pavements can be employed for parking lots, sporting facilities, and residential streets with benefits including high slip/skid resistance, noise attenuation, groundwater recharge and pollution/siltation control. Active pollution mechanisms include absorption, straining, and microbiological decomposition.  Studies indicate permeable pavements are effective in the removal of sediments, total phosphorous, nitrogen, zinc, lead, and chemical oxygen demand.  
 
This presentation outlines the application & functional advantages of Permeable Concrete Pavements, it’s specification, civil engineering design, stormwater treatment, maintenance and indicative costs.

Concrete overlays -  A review of international practice and some Australian applications
Justin Moss, Principal Pavements Engineer and Team Leader - Arcadis
Member of the National Executive of the Australian Society for Concrete Pavements


Traffic volumes and wheel loadings continue to increase on major roads in Australia.  Much of the road asset infrastructure is ageing and has exceeded its design life and design loadings.  Consideration needs to be given to extending the service life of the assets or replacing them.
Concrete overlays offer a solution to extend the service life of a pavement, preserving the inherent value of the existing asset.  Concrete overlays have been a solution in USA since the early 1990s but there has been little application in Australia.
Justin will outline the nature and application of concrete overlays and the fundamental design and construction technologies, and will explain ASCP’s program for bringing Concrete Overlay Technology to Australia.

Concrete airfield pavements – USA slip-forming practices and examples
Todd Myers, Director - TSM Civil Project Management
President of the Australian Society for Concrete Pavements


Airfield pavements are required to carry ever increasing wheel loadings with their own unique distribution patterns, and ever increasing frequencies of aircraft movements.  Thick concrete pavements offer excellent performance and low maintenance requirements.  The use of slipform pavers to construct these pavements provides substantial cost savings over fixed form construction.
Normal practice in USA and Europe is for concrete airfield pavements to be constructed using slipform pavers.  However, in Australia the only use of slipform pavers for airfield pavements has been over fixed forms.
Todd will present on the various materials, concrete mix design and construction factors required to achieve a high quality concrete pavement for airfields.  In particular, aspects of edge slump, smoothness, and dowel insertion will be addressed.

Thin Concrete Pavements
Ralph Williams, Consulting Engineer and Director, Williams Consulting Engineers Australia Pty Ltd

The concept behind the "TCP" design is that each slab of the pavement is loaded by only one wheel or a set of wheels at the same time. This significantly reduces the top tensile stresses of the slabs. With this configuration of loads versus the dimensions of the slab, the cantilever effect is reduced by the rocking of the slab as the load moves over it, so each slab supports the loads under the wheels, supported on the ground. This design method, is currently being included on a number of commercial projects in Australia now providing contractors and asset owner with a more durable and cheaper construction method than conventional pavement design.
