TRB IC Webinar on July 20 – Register Now!

Intelligent Construction Technologies Group (IICTG) committee members will be presenting at an US Transportation Research Board (TRB) webinar “Application of Intelligent Compaction Technology for Compaction Quality Control of Pavement Layers” on Thursday, July 20, 2017 from US 2:00 PM to 3:30 PM EDT.  Please register to reserve your seat NOW!

This webinar will provide an overview of Intelligent Compaction (IC) technology, including how IC can be applied to soils, bases, and asphalt layers. IC deals with the continuous assessment of compacted layer properties using roller vibration parameters and roller speed integrated with GPS to provide comprehensive compaction information. Presenters will discuss the application of IC from different viewpoints, including academia, industry, and a state department of transportation.  This webinar was organized by the TRB AFP 70 Standing Committee on Aggregates and TRB AFS 20 Standing Committee on Geotechnical Instrumentation and Modeling.

The webinar presenters are as follows from IICTG and moderated by Prof. Mehran Mazari, California State University at Los Angeles:

  • Dr. George K. Chang, Director of Research, The Transtec Group (President and Executive Committee of  IICTG)
  • Prof. Soheil Nazarian, Professor, University of Texas at El Paso (Technical Affair and Executive Committee of IICTG)
  • Dr. Jimmy Si, Transportation Engineer, Texas Department of Transportation (Technical Committee of IICTG)

 

Veta 4.2.36 Released

This is the last scheduled release for Veta 4.2 It contains several important fixes, which requires the reprocessing of existing projects. Some changes have also been made to the MnDOT filter manager. All changes are listed in the Release Notes and provided below.

Existing projects will be reprocessed upon open. As always, we recommend using a copy of existing projects when reprocessing is required. For maximum accuracy, it’s also suggested to verify locations in Spot Tests and Location/Exclusion Filters.

Import

  • Fixed: The distance unit in the file import wizard was sometimes ignored if set to Meters or Feet (Survey Feet were fine).
  • Fixed: Distance conversion (feet to meters, for example), was sometimes incorrect by small amount. The amount varies per project, but so far, we’ve only seen it off by a few inches.
  • Fixed: The alignment contained in Sakai/Topcon files was not always imported correctly.
  • Fixed: Ames and MOBA files with duplicate data were not imported correctly.

Editor

  • Fixed: Sometimes zooming to the first or last point did not work.

Filters

  • Fixed: Cold-edge and Bracket filter did not work well if files with different numbers of sensors were in the same project.
  • Fixed: Some MnDOT-generated filter groups were not linked to the data filter.
  • Fixed: Renaming generated groups did not rename the associated operation filter and could cause a crash.
  • Fixed: Removing a generated group did not remove the associated operation filter.
  • Changed: MnDOT-generated filter groups now select the date using a time filter instead of the file name. This is because a file can contain multiple dates.
  • Changed: MnDOT filter generator now allows multiple materials.
  • Changed: Performance increase for filtering and analyzing data.
  • Changed: MnDOT-generated filter groups cannot have their filters removed and generated filters cannot be added to these groups.

Spot Tests

  • Fixed: Spot tests were sometimes not shown on the map.

Sublots

  • Fixed: For thermal profiling projects, canceling the addition of a new Sublots had no effect.

Analysis

  • New: Added Clipboard copy options for the coverage table.
  • Fixed: Sublot maps for thermal profiling did not hide the paver stop areas.
  • Fixed: Sometimes the sublots were not analyzed or the wrong sublots were analyzed. This issue only occurs 4.2.
