Veta 5.1.21 Released

This important update fixes several issues.

Download Veta 5.1

Import

  • Fixed: Corrected checking for invalid coordintes for MOBA IC data. Existing projects will be automatically reprocessed.

Data Files

  • Fixed: Viewing compaction files can cause data to be incorrect or missing.
  • Change: The search tool and viewing of pass counts have been removed from this screen. Search tool may return but it is currently not possible to reliably show the pass counts on a per-file basis in this screen. If you need to see this data, use the Filters.

Sublots

  • Fixed: If the coordinate system was UTM but the Location unit in Options was not meters, the sublots length description was labeled as meters, but the sublots were actually defined using the Location unit (feet or survey feet). The actual distance and unit used by Veta were correctly displayed in the Analysis. UTM is by definition, meters.

Misc

  • Fixed: Filter groups could sometimes link to filters that no longer exist, causing a crash when applying the filter group. While this does not fix the cause, it will clean groups of bad links.

 

Dr. George Chang presents an intelligent compaction intro at Australia's first intelligent compaction workshop.

Australia’s First Intelligent Compaction Workshop a Success

Pavement engineering firm The Transtec Group led Australia’s first Intelligent Compaction (IC) workshop in Brisbane to share what agencies in the US have learned and experienced in the past 15 years of IC implementation.

IC is a roller-based technology that measures roller passes, compaction temperatures, and stiffness of compacted materials in real-time. It allows for the real-time detection of paving and compaction issues so paving crews can adjust the operation to improve the final pavement quality. Using IC improves construction quality control (QC) and efficiency to make pavements last longer and to reduce maintenance costs.

The workshop, held on May 8, brought together Australian agencies, research groups, contractors, and vendors. It was organized by the Australian Geomechanics Society and co-sponsored by Monash University, the Australian Road Research Board (ARRB), Queensland University of Technology (QUT), FSG Geotechnics & Foundations, Insitu Test, and the Australian Asphalt Pavement Association (AAPA). Topics covered included IC basics/theory/models, how IC can be implemented, lessons-learned from implementation in the US and China, a demonstration of Veta software, IC case studies from Australia, and a vibrant panel discussion.

Intelligent compaction panel discussion

Those in the panel discussion included an executive of AAPA, which plans to support road agency and industry members in the introduction of IC and address any barriers.

“The Australian Asphalt Pavement Association and its members are interested in IC as part of our industry’s commitment to continual improvement,” said Dr. Erik Denneman, AAPA Director of Technology and Leadership. “We expect that IC will lead to increased uniformity of compaction.”

Peter Evans, the Deputy Chief Engineer with the Department of Transport and Main Roads (TMR) of Queensland, was also member of the panel discussion.

“It was interesting to see how well-developed IC technology is now and its increasing use in the US,” said Evans. “I look forward to working with the industry to introduce this into TMR.”

Dr. George Chang, Director of Research at The Transtec Group, led the workshop.

“The main takeaway from Transtec’s IC workshops is for agencies, groups, and companies to fully understand IC’s benefits and see how it can be a great quality control tool,” said Dr. Chang.

The Transtec Group recently provided complete consulting support to the Missouri Department of Transportation (MoDOT) during a year-long IC and infrared scanning (IR) demonstration project. Because of the success of the project, MoDOT has committed to fully implementing IC by 2021.

Other agencies or companies interested in IC or IR—also known as paver-mounted thermal profiling (PMTP)—can get started with the Intelligent Construction Technical Support Center. Services offered include online HelpDesk support for Veta software, training workshops, field project support, and complete support packages.

IICTG and NRRA Form Partnership

The National Road Research Alliance (NRRA) has joined The International Intelligence Construction Technologies (IICTG) as an Academic Partner.
This strategic partnership between NRRA and IICTG will focus on research in various areas of intelligent construction technologies that mirror the IICTG Task Groups:
TG1- Intelligent Compaction
TG2- Paver-Mounted Thermal Profiling
TG3- High Precision Surveys/LiDAR/Drones
TG4- 3D Design/Modeling and Automated Machine Guidance (AMG)
TG5- Underground Utility Positioning
TG6- Building Information Modeling (BIM) for pavements
TG7- ICT Data Standards/Exchange/Management
TG8- 3D Printing for Pavements
TG9- Artificial Intelligence/Deep Learning

Veta 5.1.16 Released

This update addresses problems that will prevent downloading data directly from MOBA.

Download Veta 5.1

Import

  • Fixed: Downloading MOBA data could fail if a file had no data.
  • Change: Server addresses for downloading MOBA have been updated. It is not known how long previous 5.x versions will be able to download MOBA data.

Veta 5.1 Released

We are pleased to release Veta 5.1. We have included support for MOBA intelligent compaction files, added a new type of location filter, added charts that can be used for quality control, and created a report to list all filter settings.

Because this version only contains new features and fixes, it should be used to replace 5.0. Due to limited resources, we are currently planning to support only 5.1+, not 5.0.

Download Veta 5.1

Installation Notes

  • Microsoft .NET 4.6.2 is required.
  • Windows 7 SP 1 is the minimum supported operating system.
  • Veta 5.1 can be installed on the same machine as previous versions.
  • Veta 5.1 can open projects created in previous versions, but not vice-versa.

Import

  • New: Added support for MOBA intelligent compaction files.
  • Fixed: Adding a data file that did not contain any new data could cause a crash when viewing “Imported file name” for an operation filter.

Filters

  • New: Added a new location filter that be created using only one line from an alignment and offsets. For example, 12 to 24 feet from the centerline. This allows the use of alignments that do not have all lanes defined.

Sublots

  • Fixed: Changing most of the values did not clear the sublots.

Analysis

  • New: Added quality control charts using data from sublots. This is the first pass at creating reports that can help for quality control.

Reports

  • New: Created a new report that lists all filter settings for data lot filter groups. This provides an easier way to check for filter groups that may not have the correct settings.
  • Change: The screen now attempts to only show the options that are applicable and will disable the “Create” button if the selected options will not produce a report. Note there are still some rare scenarios that will not create a report, but these should only be scenarios that are not practical.

40 Years of CCC Symposium, Nov. 29, 2018

The 40th Years of Continuous Compaction Control (CCC) (or called Intelligent Compaction – IC in the US) Symposium will be held in Vienna, Austria, on November 29, 2018. The abstract will be due on April 30th!! Check out the conference website for further information (www.igb.tuwien.ac.at/en/ccc/).

Veta 5.0.51 Released

This version fixes issues with importing data.

Download Veta 5.0

Import

  • Fixed: UTM zone was sometimes detected incorrectly.
  • Fixed: Veta downloading of Topcon data. This issue was found during testing and has not been reported in practice. This could happen in two scenarios:
    1. Downloads of Topcon data are occurring in multiple copies of Veta and the date ranges overlap. This can result is the wrong data being used for a project, but should be apparent upon review.
    2. Topcon data is downloaded for a site. Without closing the download window, the site is changed and data is downloaded again. Veta will not download the data for the new site.
  • Change: EPSG codes for all OCRS zones are now recognized. Codes for the new zones did not exist until recently.
