Veta 4.3 Released

We are pleased to announce the release of Veta 4.3! All changes are listed in the Release Notes and also provided below.

Download Veta 4.3

Import

  • New: Added support for Volvo soils files.
  • New: Added support for the Oregon Coordinate Reference System

Map

  • New: Search tool to list all data near a selected location.

Analysis

  • Fixed: A given location in the thermal profile would be colored differently depending on the x-axis starting value.
  • New: The semivariogram for thermal profiling has been replaced with a “transverse semivariogram”. The standard semivariogram did not always work well for thermal profiling data, especially when there is large temperature segregation.
  • New: Added a legend for the thermal profile.

Reports

  • New: Added option to choose if sublots should be reported. If not, only the summary will be reported, which can drastically reduce the size and time needed to create reports.
  • Change: File export has been simplified to only export using the selected coodinate system.

Misc

  • Change: Many performance improvements.
  • Change: Location information now lists Northing/Latitude first, followed by Easting/Longitude.
  • Change: Added support for very large projects.

Veta 4.2.37 Released

This release only fixes some usability issues with filters. All changes are listed in the Release Notes and provided below.

Filters

  • Fixed: Various issues with the ability to select, delete, and rename filters.

IC Champ Dr. George Chang Receives ASTM Award

Dr. George K. Chang, The Transtec Group’s Director of Research and a champion for Intelligent Compaction, is the recipient of the 2017 Billiard-Stubstad Award. ASTM International Committee E17 on Vehicle – Pavement Systems presented the award to Dr. Chang in recognition of his contributions to improving the use of inertial profiler data around the world and his substantial contributions to the roughness standards preparation and maintenance activities for committee E17.

“Through his work in the field of the measurement, processing and analysis of pavement profiles, Dr. Chang had become a well-known expert in the field of pavement smoothness,” said Dr. Zoltan Rado, chairman of the E17 committee. “He had used and dedicated his expertise and knowledge in the technical and practical pavement profile measurement area to bring unique administrative contributions and leadership in the standards development work of ASTM E17. His work within the E17 committee had made it possible for the committee to develop and maintain relevant standards that support the industry and user communities as well as state and national regulatory bodies with pavement roughness measurement and analysis standards.”

Dr. Chang has also previously received the 2007 Kummer Lecture Award and the 2010 Meyer-Horne Outstanding Achievement Award from ASTM.

The Billiard-Stubstad Award was established in 2015 in honor of Gary Billiard and Richard Stubstad. The award is intended to recognize individuals who have made exemplary technical, practical, and/or administrative contributions to the pavement engineering community through their standards development efforts.

ASTM Committee E17 on Vehicle-Pavement Systems was formed in 1960. The Committee has 11 technical subcommittees that have jurisdiction of over 73 standards, published in the Annual Book of ASTM Standards, Volume 4.03. These standards have and continue to play a preeminent role in all aspects important to pavement management technologies, vehicle pavement interactions and intelligent transportation systems.

Dr. Chang is a world expert on pavement smoothness and intelligent compaction. He has extensive experiences in pavement engineering consulting, research, training, and pavement software development. He has been actively involved in many projects that relate to pavement surface characteristics–including friction, smoothness, texture, tire-pavement noise–materials structure design, and intelligent construction technologies. Dr. Chang’s unique expertise is in system/model integration, data collection and analysis, and asset management. He has developed many pavement engineering software applications that have been used as standards around the US and the world. He also co-founded the International Intelligent Construction Technologies Group (IICTG) association in 2016.

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:

 

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.

Download Veta 4.2

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.
