摘要: Rutting is a common distress in pavements with asphalt concrete surfaces. For many agencies the magnitude of rutting plays a significant role in their rehabilitation decision process. As a result many different approaches have been taken to address the prediction of rutting and its causes. As more agencies shift to the collection of transverse profiles instead of rutting to provide greater repeatability of the measurements and to avoid debates regarding the appropriate straightedge length, additional analytical possibilities are being identified. One such analytical opportunity explored in the present investigation suggests that the area under the transverse profile can be used to hypothesize the origin of the rutting from within the pavement structure. This in turn allows for greater prediction capabilities when the cause of the distress can be further isolated in this fashion. With the benefit of the numerous transverse profiles collected as part of Long-Term Pavement Performance Program monitoring, investigations have been conducted to sort the test sections into data subsets based on the areas described above. Neural networks were developed to model these data subsets. The models are in turn compared with other previously developed models to evaluate the impact of sorting by areal magnitude on the prediction of rutting.
