40th Year Celebration of IC/CCC

We’ve just celebrated the 40th anniversary of the invention of Continuous Compaction Control (CCC) – later dubbed as Intelligent Compaction (IC) – in Vienna, Austria on Nov. 29, 2018. More than 160 IC-CCC experts (pretty much include all IC-CCC research, development, and implementation from all of the world) from more than 2 dozen countries have attended this historical event. This Symposium proceedings is published by the Technical University of Vienna (TU Wien). Here is also a historical moment with the inventor of IC-CCC in the attached photo (from the left to the right): Prof. Antonio Correia of Minho University, Portugal (leader in EU IC-CCC specification and implementation, Vice President of IICTG), A. Sandstrom of Geodynamic, Sweden (inventor of IC-CCC), Dr. George Chang of Transtec Group, USA (leader in US IC-CCC specification and global implementation, President of IICTG), and Prof. Soheil Nazarian of University of Texas – El Paso, USA (leader in US IC-CCC research, Executive Member of IICTG). IC-CCC has come a long way for the past 40 years! It is anticipated to be elevated to the next levels with the integration with other Intelligent Construction Technologies (www.IICTG.org) in the decades to come!

Download Veta 5.2

Import

  • New: Added support for Voegele thermal profiling files.
  • New: If a file does not contain speed data, it will be calculated.
  • Fix: A fix in 5.2.47 caused a bug that could cause incorrect merging of Laser Test Roller and MOBA thermal files. Existing projects will be reprocessed.
  • Fix: The cold-edge filter did not work when multiple files were selected in the operation filter.
  • Fix: If a project contains files that not have a Data lot name and files that do not have a Data lot name, the latter might not show in the filtered results. The same problem also existed for the Machine name.
  • Change: Files that do not contain a Data lot name will be assigned a Data lot name of, “(None)”. The same also applies to the Machine name.
  • Change: Existing MOBA thermal profile projects will be reprocessed to read the data lot name.
  • Change: Revised calculations for heading and speed for non-gridded data.

Misc

  • Fix: Projects with a very large number of imported files could not be opened.

Veta 5.2.57 Released

Compilation of miscellaneous fixes and some changes.

Download Veta 5.2

Import

  • New: Veta-recognized coordinate systems are now read from Leica files.
  • Change: The Roadway ID in MOBA thermal profiles will be used as the data lot name. Existing projects will not be changed.

Filters

  • Change: Exclusions have been moved to a subfolder. The text, “Exclusions – “, is no longer added to new Exclusion filters.
  • Fixed: Sometimes a generated operation filter is not automatically removed when it should be. It is not known what causes this, but these groups will be removed when the project is reopened.
  • Fixed: More accurate creation of station-based location filters. Existing filters will be updated when a project is opened.
  • Fixed: Detection of some instances of using incorrect stations for a location filter. These instances will now correctly not create the filter instead of creating one with incorrect locations.
  • Fixed: Sometimes filter creation options were missing from the toolbar.

Analysis

  • Fixed: Changing the sorting for the differential table caused the map to highlight the wrong sublot.

Misc

  • Fixed: Some Windows Regional Settings would cause a crash at startup.

 

Veta 5.2.47 Released

The highlights from this update are some fixes related to stationing, MOBA thermal profiling files, and TDS (standard file format) files. Existing MOBA thermal profiling and TDS projects will be reprocessed.

Download Veta 5.2

Import

  • Fixed: TDS files were not imported correctly.
  • Fixed: MOBA thermal profiling files that were continued on a later date did not have the correct times.
  • Change: Account for new paveproj files saved by MOBA’s PPM software.

Alignments

  • Fixed: LandXML files with multiple alignments only used the stations from the first alignment. Existing alignments will be reprocessed. Filters using these alignments will need their selections checked.
  • Change: Initial alignment names now include the file extension (kml, kmz, or xml) to differentiate between multiple alignments with the same name.

Filters

  • Fixed: A copy of a generated filter could not be deleted or renamed.
  • Fixed: Changing the selected filter group back and forth could cause the “Apply filter group” button to be incorrectly hidden. Because it is not possible to determine the correct state in previous projects, existing projects will always show the button until the filter group is applied.
  • Fixed: Making a copy of a data filter would list it twice.
  • Fixed: Station offsets for new exclusion filters were always in meters.
  • Change: New exclusion filters include the default text, “Exclusion – “.

Analysis

  • Fixed: Analysis might fail if Speed or Temperature were not selected.

Take the Guesswork Out with IC

There is an excellent article on IC: Night Vision: Intelligent Compaction giving paving contractors better results in the dark. 

IC is a no-brainer! It’d help to help any roller operators to take the guesswork out! Here is the quote from Oregon DOT: “There’s not too many technologies that I’m aware of where you could do a 10-percent increase just by using technology,” says Larson. “But that’s exactly what we do with intelligent compaction.”

Veta 5.2 Released

We are pleased to announce the release of Veta 5.2. This version focuses on alignments and additional file support. We added limited support for LandXML files, including the ability to read station information. Support was also added for Leica compaction files and MOBA EVIB compaction files. Zip and Gzip files can also be imported, eliminating the need to extract the data first. Finally, we added support for the AASHTO draft specification for intelligent construction data files. We currently support compaction, thermal profiling, and laser test roller files. Additional information can be found on the new Developers page. All changes are listed below.

Download Veta 5.2

Installation

  • Microsoft .NET 4.6.2 is required.
  • Windows 7 SP 1 is the minimum supported operating system.
  • Veta 5.2 can be installed on the same machine as previous versions.
  • Veta 5.2 can open projects created in previous versions, but not vice-versa.

Import

  • New: Added support for TDS files (standard file format) for compaction, thermal profiling, and laser test roller.
  • New: Added support for Leica compaction files.
  • New: Included support for EVIB when using MOBA compactors.
  • New: Zip and Gzip data files that contain only one file are now supported.
  • Change: Specifying the machine vendor is no longer necessary, so the dropdown was removed from the import wizard.

Data Files

  • Fixed: Viewing files could cause data to be incorrect or missing.

Alignments

  • New: Added support for KML.
  • New: Added limited support for LandXML alignments and stations.
  • Change: Alignments were originally used only for drawing on the map but have now become an integral part of the software. To account for this, the nomenclature has changed:
    • Alignment is now Alignment File (each file can contain multiple alignments)
    • Drawing is now Alignment (stations and station equations/regions are defined here)
    • Object is now Line

Filters

  • New: The offset location filter can now use stations.
  • Change: The Position input for offset location filters has been removed. Positive numbers are the right of the reference line, negative to the left.

Analysis

  • Fixed: Thermal profile did not always redraw.

Misc

  • New: Added a Zoom to Station option.
  • Change: The options “Use SI units” and “Location unit” have been moved to the Project Properties. New projects will use the most recently used values for these items as default.
  • Change: Generated final coverage for all passes that only contain static data will no longer show ICMV.
  • Change: Improved map performance.
  • Fixed: Some previous projects (3+ years ago) could not be opened successfully.
