ProVAL
ProVAL (Profile Viewing and AnaLysis) is an engineering software application that allows users to view and analyze pavement profiles in many different ways. It is easy to use and yet powerful enough to perform many types of profile analyses. ProVAL is a product developed by the Transtec Group through a contract with the US Federal Highway Administration (FHWA) and the Long Term Pavement Performance Program (LTPP).
IT is coming!
ProVAL 3.0 is in the works! ProVAL is being revamped to enhance its usability while maintaining technical continuity in 3.0. Some people already have a taste of the ProVAL 3.0 preview version during RPUG 2008. Stay tuned for further announcement!
ProVAL 2.73 PCM Makes Profiler Certification a Breeze
Ever feel frustrated doing hundreds of cross correlations to produce reports for profiler repeatability tests and accuracy tests (as in the AASHTO PP49 Standard Practice for Certification of Inertial Profiling Systems)? A ProVAL workshop attendee has reported that it took one of his engineers 21 days to finish an analysis for a profiler certification data set -- prior to the PCM's debut!
The pain is no more ... when you have ProVAL 2.73! An easy-to-use yet powerful feature called "Profiler Certification Module" or PCM makes this process a joy with simply a few mouse clicks!
The classic Cross Correlation module has been revamped to include powerful features for in-depth analysis! Have a quick look at what's new in ProVAL 2.73! With ProVAL 2.73, you can now easily evaluate whether a profiler can produce repeatable and accurate results. Download a copy of ProVAL 2.73 and start the fun now!
Testimony on Profiler Certification Module (PCM)"I want to thank you for the Profiler Certification Module that was added to ProVAL in 2007. Using the Profile Certification Module the Wisconsin DOT was able to evaluate all the Profilers used on WisDOT Paving Projects for both HMA and PCC pavements in two days. We were able to perform profile testing, analyze the profile data in the Profiler Certification Module and determine if a 92 percent repeatability score and a 90 percent accuracy score had been achieved within a few minutes after results were submitted. This software is really amazing and if I can use it anyone can use it. Thank you for a tool that has taken the guess work out of profiler approval and provides a uniform standard in determining profiler acceptability. Keep up the good work." - Terry A. Treutel, Materials Laboratory and Field Testing Specialist, Wisconsin Department of Transportation. RPUG 2008 Presentation on WisDOT's ExperiencesTerry Treutel also made a presention during RPUG 2008 to share the Wisconsin DOT's experiences with the ProVAL PCM and ride specifications. This is a great testmonies for the impacts of using ProVAL to speed up imeplementation of IRI specs! |
