Permanent Deformation Characteristics of Flexible Pavement Under Palm Oil Freight Truck Loading

Most of previous studies employed dynamic stability test and Hamburg wheel tracking to investigate permanent deformation characteristics asphalt concrete (AC) layer. However, the performance only focuses on surface course neglected influence middle layer base course. The present study investigates four (4) different configurations flexible pavement analyzes contribution AC total as response various truck’s speed, hauling loads, loading cycles. Finite element modeling was performed evaluate critical locations below tire tread single unit two-axles truck with greatest magnitude determine optimum configuration by considering linear viscoelastic behavior two types mixtures. It can be concluded that largest is measured right edge outer tire. due increase in speed about 14.81% 16.39%, while loads well number passing trucks around 14.76% 16.44%. On other hand, from reaching 83.61% 85.19%, achieving 83.56% 85.24%.
