Exploratory Analysis of Long-Term Performance of Pavement Using Reclaimed Asphalt Pavement
As the development of automatic pavement performance data collection equipment, the amount of data faced by pavement managerial agencies becomes intractable. Due to the massive amount of data available at the pavement management system, it is difficult to determine which data element is the most important. This paper aimed to addressing this issue through an exploratory analysis of the data from the long-term pavement performance (LTPP) program. The data primarily collected from the specific pavement study 5 (SPS-5) were analyzed in the study. The results in the study showed the cracking especially the alligator and wheel path longitudinal cracking significantly impacted the deterioration of the pavements’ long-term performance. The rutting was more crucial to the riding quality of the asphalt pavement than the cracks. The sections containing up to 30% RAP achieved similar performance in terms of IRI, wheel path longitudinal cracking, and transverse cracking. Compared with section using virgin HMA only, sections containing RAP showed less rutting.
