Detection of segregation in asphalt pavement materials using the ARAN profile system

In a research project conducted for the New Jersey Department of Transportation (NJDOT) several segregation detection and measuring methods were evaluated to identify the best technology. These included; visual identification, thermal imaging, nuclear density gauges, sand patch testing and several laser texture-measuring devices. After evaluating the advantageous and disadvantageous of each method, the laser texture-measuring device was selected since it offered rapid data collection phase without interrupting traffic. The ARAN was selected because the NJDOT had one available. By combining the level of segregation and extent of each level of segregation, an AREA index was developed to determine the acceptance or nonacceptance of a pavement section. New segregation detecting and monitoring software, "NJTxtr" was developed by combining the use of the ARAN-collected pavement-texture data and the above methodologies to determine whether a pavement section is acceptable or unacceptable based on the level of segregation present. If a pavement section is acceptable, the software determines the pay adjustment factor to be used; if segregation is present, it suggests remedial actions for the segregated areas. The software and the acceptance levels within the software are currently being reviewed to determine acceptable limits for projects.
