About ProVAL
ProVAL (Profile Viewing and Analysis) is an engineering software application used to view and analyze pavement profiles. It is easy to use, yet powerful enough to perform many types of profile analyses. ProVAL is a product sponsored by the US Department of Transportation, Federal Highway Administration (FHWA) and the Long Term Pavement Performance Program (LTPP).
Key features
-
Profile viewing: Pavement Profile Standard File (.ppf); UMTRI (.erd, .bin); Ames (.ldf, .adf); Dynatest (.rsp); TxDOT (.txt, .dat, .pro); and KJ Law (.a*, .p*).
-
Profile Editing: Manipulate profile data in many aspects, including cropping and filtering.
-
Ride Statistics: Report ride indexes such as International Roughness Index (IRI), Half-car Roughness Index (HRI), Mean Roughness Index (MRI), and Ride Number (RN).
-
Power Spectral Density (PSD): Analyze the wavelength or frequency contents of profiles.
-
Profilograph Simulation: Simulate Profilograph traces, report Profilograph Indices, etc.
-
Rolling Straightedge Simulation: Simulate Rolling Straightedge traces.
-
Profile Synchronization: Synchronize profiles and determine their repeatability/accuracy based on cross correlation.
-
Profiler Certification: Produce repeatability tests and accuracy tests for profiler certification programs.
-
Precision and Bias: Classify profilers based on the ASTM E950 standard.
-
Smoothness Assurance Module (SAM): Provide ride quality reports and improve smoothness from pavement grinding simulation.
-
Automated Fault Measurement (AFM): Automatically identify joint locations and estimate joint faulting from profile data.
-
Optimal WIM Locator (OWL): Evaluate Weight-in-Motion measurement errors based on profile data.
