  1. 1. Packing theory-based Framework for Performance Evaluation of Unbound Granular Materials

    Författare :Tatek Fekadu Yideti; Björn Birgisson; Denis Jelagin; Tutumluer Erol; KTH; []
    Nyckelord :;

    Sammanfattning : Enhancing the load bearing quality of granular layers is fundamental to optimize the structural performance of the pavements. Unbound granular materials are one of the most used materials in the base layers of pavements. There have been growing interests on the behavior of unbound granular material in road base layers.

    Sammanfattning : Recently, there has been growing interest on the behaviour of unbound granular material in road base layers. Researchers have studied that the design of a new pavement and prediction of service life need proper characterization of unbound granular materials, which is one of the requirements for a new mechanistic design method in flexible pavement.
