LTPP DiVA Online is
an application that can assist in analyzing distress information by graphically
displaying distress data. The distress data can be displayed to show a time
series/time history of a pavement section under evaluation. DiVA provides two
report types, graph and data table. The data table report can be exported.
Also, the program displays a current trend line and a variability (standard
error) band. The application can analyze several surveys at the same time. Also
the application gives access to images related to each survey pictures,
distress maps and scans of 35mm film by the LTPP’s automated distress surveying
contractor PASCO USA. The application was originally developed by Fugro/BRE as
a quality control/quality assurance review tool for the LTPP distress data.
The application can help SHA as a review tool prior to data entry into any
Pavement Management System (PMS) to examine the data collected; DiVA can be run
to compare the surveys results against all previous surveys and review any
abnormalities. Trend discrepancies can be evaluated for possible explanations
such as:
Maintenance or rehabilitation activities.
Differences in interpretation.
DiVA can be used by states to check distress data to calibrate the AASHTO Design guide.
DiVA can be used to review variability in PMS distress data and to lessen the impact of that variability on Pavement Management systems.
