I have been asked to perform some pavement capacity calculations at a Port in Australia.
The majority of pavements are on reclaimed land, with the pavement consisting of dredged sand placed over a layer stiff clay with an asphalt wearing course.
I am able to ascertain capacities for wheel loads as there is an abundance of literature from the road construction industry.
However the port handles a large quantity of bulk cargoes which are stockpiled on the pavement. Some of this material is quite dense (eg Mineral Sands with density of 2.5t/m3). I need to calculate the maximum stockpile height allowable for the different cargo densities. Unfortunately I cannot locate much information on the effect of this type of load on flexible pavements.
My initial impression is that stockpiling of material on the pavement will not cause failure but rather excessive settlement of the pavement.
Does anyone have any idea of the methodology for this type of analysis or who can refer me to any relevant literature.
