NRRA New Research on Intelligent Compaction Measurement Values (ICMV)

The National Road Research Alliance (NRRA) has just funded a research “Evaluation of Levels 3-4 Intelligent Compaction Measurement Values (ICMV) for Soils Subgrade and Aggregate Subbase Compaction”. Dr. George K. Chang of Transtec Group (also President of ISIC) and Prof. Soheil Nazarian of UTEP
(also Executive Committee member of ISIC, www.ISIC.org) will lead this research project. The goals of this research are to (1) evaluate Level 3-4 ICMV systems against Level 1-2 ICMV systems for soils and base compaction, and (2) develop a blue print for future certification procedures of IC. The final deliverable is expected to be by the end of 2020. Further information can be found on this NRRA webpage.

Free Webinar on Intelligent Compaction by ARRB and Transtec Group

As a part of the Australian NACOE research efforts om Intelligent Compaction (IC), ARRB and Transtec Group will conduct a free webinar on IC and the summary for the IC workshop and field demo held in SW Queensland, Brisbane, Australia from June 3-4, 2019. The webinaer wil be held on Jul 02, 2019 at 12:00 PM AEST (Australian eastern time zone). The registration link is here. The followings are further details.

NACOE – Introduction to Intelligent Compaction (IC)

Join us for a webinar on Jul 02, 2019 at 12:00 PM AEST.

Compaction is one of the most important processes in roadway construction. It is necessary in order to attain high quality and uniformity of pavement materials, which in turn better ensure long-lasting performance. In this webinar, the presenters will introduce Intelligent Compaction (IC), which refers to the compaction of road materials, such as soils, aggregate bases, or asphalt pavement materials, using modern vibratory rollers equipped with an integrated measurement system, an onboard computer reporting system, GPS based mapping, and optional feedback control. IC rollers facilitate real-time compaction monitoring and timely adjustments to the compaction process by integrating measurement, documentation, and control systems. IC rollers also maintain a continuous record of color-coded plots, allowing the user to view plots of the precise location of the roller, the number of roller passes, and material stiffness measurements.

Our two presenters are Dr. George K. Chang, P.E., Director of Research, The Transtec Group, USA
(also President of International Society for Intelligent Construction – www.IS-IC.org) and Dr. Jeffrey Lee, Ph.D., CPEng, F.IEAust Principal Engineer, Australian Road Research Board

This is part of the NACOE P105 project which looks into the implementation of the IC technology. Results from a recent field demonstration conducted in June 2019 will also be presented

Participants please note – the session will commence at 12 pm Australian Eastern Standard Time (AEST). There may be time zone differences that apply. It is recommended that you connect to the webinar 15 minutes prior to allow sufficient time for potential connection delays.

After registering, you will receive a confirmation email containing information about joining the webinar.

The First US-Japan ICT Workshop a Success

The first US-Japan Intelligent Construction Technologies (ICT) workshop as held in Tokyo on April 24, 2019. It was well-attended and successful! Dr. George K. Chang, Transtec Group, USA (also President of International Society for Intelligent Construction – ISIC – recently changed from IICTG), Prof. Soheil Nazarian, UTEP, USA (a Executive Committee Member of ISIC), and Emeritus Prof. Fumio Tastuoka, University of Tokyo and Tokyo University of Science as well as other speakers have presented the latest and greatest ICT. Industry sponsors include Sakai Heavy Industry, AKT, etc. This workshop has boosted Japan’s interests in ICT and will facilitate implementation there!

ICTG – now ISIC – 2019 Conference a BIG Success

The 2nd International Intelligent Construction Technology Conference (IICTG) was a big success from April 16 to 17, 2019. The conference was held in Beijing, China after the first conference in Minnesota, USA in 2017. There are about 300 attendees for the 2019 conference, topping the one in 2017, pushing the momentum for intelligent construction to a higher level. During this conference, the IICTG committee has made a very important decision to rename IICTG as ISIC – International Society for Intelligent Construction. The Chinese translation is “国际智能建设学会”. With this new name and broaden scope, ISIC will provide the unique platform for the intelligent constructions for decades to come! Download the conference brochure for a glimpse at the conference agenda, presentation, et. Further details about the conference contents, presentation summaries, technical panel discussions, and committee meeting will poste  on the IICTG website www.IICTG.org (soon be updated to www.IS-IC.org ).

Analysis

  • Fix: Analysis crashes.
  • Fix: Wrong thresholds were drawn on the Differential and Segregation Quality Control charts.

Filters

  • Fix: Filter group manager crash.
  • Fix: Renaming a generated filter group did not automatically update the operation filter names in the coverage analysis or in the filter screen.
