    Development of a Flexible Pavement Design Framework for Autonomous and Connected Trucks
    Gungor, Osman Erman ;
    Al-Qadi, Imad L
    2018-11-01 | PDF
    Lateral position of loading, which is an important input to pavement design and analysis, is a random phenomenon for human-driven trucks because they do not follow a straight path as they travel. Therefore, in the pavement-design community, this variable has been called “wheel wander” and conventionally considered in an implicit way. However, with ...
