Relationship between Climate Type and Observed Pavement Distresses
Climate is assumed by pavement engineers to have an effect on pavement performance. The United States Air Force (USAF) has measured the pavement condition of their airfield pavements using Pavement Condition Index for over 20 years, resulting in a good record of pavement performance for various pavements world-wide. Most pavement sections have been inspected multiple times, resulting in over 17,000 data points. This research used these data to determine if a statistically significant relationship existed between the distresses observed on a pavement and the climate region in which the pavement was located. The specific climate factors examined were moisture (wet, dry) and temperature (freeze, no freeze). Two-factor testing was performed using the data to determine the main effects and the interaction effect of the factors on the types and quantities of distresses exhibited by pavement. Results of the analysis indicated that there was a relationship between climate type and certain distresses, while other distresses were unaffected by climate type.
