ProVAL is an engineering software application used to view and analyze pavement profiles. It is easy to use, yet powerful to perform many types of profile analyses.
Users can import profiles from various file formats and save them in the Pavement Profile standard file type. Entire analysis projects can be saved, which preserves user information and analysis inputs. After analyses have been performed, the user can print a report of the original profiles and the results of any analyses performed.
Types of analysis that PROVAL can perform:
- Profile Editing (to manipulate profile data in many aspects including cropping and filtering);
- Standard Ride Statistics, such as International Roughness Index (IRI), Half-car Roughness Index (HRI), Mean Roughness Index (MRI), and Ride Number (RN);
- Fixed-Interval Ride Statistics (to report roughness indexes at a fixed interval);
- Continuous Ride Statistics (to report roughness continuously with a sliding interval);
- Power Spectral Density (PSD) (to view the wavelength or frequency content of profiles);
- Profilograph Simulation (to simulate Profilograph traces, report Profilograph Indices, etc.);
- Rolling Straightedge Simulation (to simulate Rolling Straightedge traces);
- Localized Roughness Identification (to identify localized roughness locations based on the Texas DOT Specification - Tex-1001-S – not available for ProVAL 3 );
- Cross Correlation (a powerful tool to synchronize profiles and to determine their repeatability);
- Profiler Certification (a tool to produce repeatability tests and accuracy tests for profiler certification programs);
