LTPP - Distress Viewer and Analyzer Software (Online)

Diva is a software 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 data table and graph. The data table report can be exported to Excel. Also, the program displays a current trend line and a variability (standard error) band. The application can analyze several survey sections at the same time. 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: (1) maintenance or rehabilitation activities; or (2) differences in interpretation. Diva can be used by states to check distress data to calibrate the AASHTO Design guide. Diva can also be used to review variability in PMS distress data and to lessen the impact of that variability on Pavement Management systems.
