Workshop on Intelligent Compaction

Dr George Chang - Keynote Presenter

AGS QLD, the Australian Road Research Board (ARRB) & Monash University invite you to attend the 1st Australian workshop on Intelligent Compaction (IC).

This highly interactive workshop will be led by a global leader in the IC technologies field – Dr. George Chang – and aims to bring together industry participants from Australia and overseas to dissect the innovative technology.

About Intelligent Compaction

Intelligent Compaction (IC) refers to the compaction of road construction materials – including a full range of natural soils, fills, aggregate or asphalt pavement materials – via use of modern vibratory rollers equipped with an integrated measurement system, an onboard computer reporting system, Global Positioning System (GPS) based mapping, and optional feedback control. Rollers instrumented with IC technologies facilitate real-time comparative compaction monitoring and timely adjustments to the compaction process by integrating measurement, documentation, and control systems. IC rollers also maintain a continuous record measured stiffness / compaction, allowing the user to view plots of the precise location of the roller, the number of roller passes completed, and material stiffness measurement during each roller pass – information that can either be utilised during live compaction work or to add to QA documentation.

Achieving adequate and uniform compaction is one of the most important requirements in roadway construction, as the installed state of the construction material will dictate their long-term performance. Conventional compaction procedures may result in inadequate and/or non-uniform material compaction, whilst the industry standard of spot density testing for QA requirements does not guarantee such defects are adequately identified at the time of construction.

IC technologies helps users overcome this issue by optimising the compaction process. As the compaction methodology that results in optimum support, stability, and strength of specific road construction materials is complex and often varies the improved test coverage and near-instantaneous availability of results offered by IC instrumented plant has the potential to significantly aid the uniformity achieved by the applied material compaction processes.

Dr Chang has delivered intelligent compaction / construction related workshops around the world via his recognised energetic and lively teaching style, and been the recipient of numerous prestigious honours for his outstanding contribution to the IC technologies field.

Workshop Goals

The workshop aims to allow participates to:

  • Develop an understanding of IC technologies, and the opportunities (and limitations) it presents to earthworks and pavement construction projects
  • Raising awareness of Intelligent Compaction (research projects and implementation by industry)
  • Networking opportunity for those interested in Intelligent Compaction (especially in Australasia)
