Formation and growth of multiple, distinct ice lenses in frost heave Open
This paper presents a fully coupled thermo‐hydro‐mechanical (THM) model which simulates frost heave in fully saturated soils. The model is able to simulate the formation and growth of multiple distinct ice lenses. The basic equations of th…

Assessing soil index parameters to determine the frost susceptibility of crushed rock aggregates Open
In Norway, crushed rock aggregates are widely used in all layers of pavement infrastructures. Frost heave severely affected the Norwegian road network during cold winters of 2009/10 and 2010/11, including newly built roads. In 2016, the Fr…
Transport coefficients and pressure conditions for growth of ice lens in frozen soil Open
In this paper, the transport of sub-cooled water across a partially frozen soil matrix (frozen fringe) caused by a temperature difference over the fringe, is described using non-equilibrium thermodynamics. A set of coupled transport equati…
Laboratory investigation of frost susceptibility of crushed rock aggregates and field assessment of frost heave and frost depth Open
In Nordic countries that experience seasonal frost, understanding how it affects the service life of linear transport infrastructures such as roads and railways is essential. Frost action both regroup frost heave and thaw weakening process…
