| Abstract | Cement treated reclaimed asphalt material (RAM) and polyethylene terephthalate (PET) plastic waste are related to reutilizing the landfills to preserve natural quarry aggregates and to minimize the dumping issues. This study aims to contribute to a better overview of the performance of cement-treated pavement base layer utilizing RAM and PET. In particular, unconfined compressive strength (UCS), flexural strength (FS), and indirect tensile strength (ITS) tests were conducted to evaluate the strength characteristics of the CTB. The RAM and PET fibres are blended at different proportions (95/5, 70/5, 45/5, and 20/5 of RAM/PET), along with 5 and 10% cement content by weight of aggregates. The investigation shows reclaimed asphalt material increases the optimal moisture level and, consequently, decreases the maximum dry density. All the stabilized blends complied with the UCS requirement for granular materials in the cement-treated foundation base except for 95 and 70% RAM proportion. Moreover, a cost analysis comparison has been calculated and the results indicate a 22% reduction in the cost of constructing flexible pavements when an optimum amount of RAM is implemented in the base layers. |
