  5. 3. On the Dynamics of Porous Media - Application to Road and Railway Structures

    Author : Bernd Lenhof; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poromechanics; dynamics; railway; multiphasic mixture; hydro-mechanical modeling; internal erosion; road; porous media;

    Abstract : Load-bearing road and railway structures normally consist of layers of particulate porous materials, often with bitumen-based binders. The layered system is subjected to dynamic loading from traffic, which inevitably causes material deterioration that enhances permanent surface deformation. READ MORE
