“…The test stops after 45 minutes or at rut depth of 15 mm. In this study, 12.7 mm permanent deformation failure criterion which concurs with the Asphalt Institute failure criterion, and Hamburg wheel tracking termination point, was selected [4,29]. The Linear Variable Differential Transducer (LVDT) monitors the rut depth at the center of the slab specimens.…”

Recycling of waste materials has significant environmental and economic advantages. Plastic containers and steel slag waste solids were incorporated in Stone Mastic Asphalt (SMA) and the rutting performance of modified asphalt mixtures was investigated. Slab specimens with three percentage of Polyethylene Terephthalate (PET) including 3, 5 and 7 percent in two forms (PET particles and PET fibers) were prepared and wheel tracking test was performed. For various samples, rutting profiles were modeled by the Zhou model in the MATLAB environment. It was found that modified samples had better capability to resist permanent deformation. Induced rutting depth was the lowest for specimens modified with 5 percent PET followed by 7 and 3 percent, respectively. Moreover, adding PET in the form of fiber was more effective and exhibited the lowest damage ratio. Based on the obtained results, modified samples with 5 percent PET fiber caused 35 percent less rutting. According to life cycle ratio analysis, in average S-5P-F lasted 3.35 times more than the slag control sample.

“…Poor performance of unmodified asphalt specimens has led researchers to improve the performance of bituminous mixtures [1,2]. Permanent deformation is one of the major and common distresses on roads that many researchers have tried to address [3,4].…”
