VARIABILITY OF FILM-DERIVED PAVEMENT DISTRESS DATA

In this paper, the findings of an effort undertaken by the U.S. Federal Highway Administration Long-Term Pavement Performance program to assess variability of distress data collected using a photographic method are presented. The primary source of data are the results of a distress survey conducted on 12 pavement test sections, including 6 asphalt concrete and 6 portland cement concrete pavements. Distress surveys were performed by experts, individual raters, and 2-person teams. A consensus survey on the pavements by a group of experts based on the photographic method was also conducted. A reference rating of the distress present on the same 12 test sections was performed using a consensus manual rating method by the same group of experts. Variability of the film-derived distress data was evaluated and both apparent bias and precision for the data were quantified. Results indicate that 2-person teams interpreted data more consistently.
