Influence of frost and water on base-layer material containing mica (English)
Abstract [sv]

Controlled conditions offer a possibility to determine the influence of free mica grains in an unbound base layer during simulated frost heave and thaw cycling. By ensuring a similar grain size distribution between sample materials, and that the test samples have been soaked in water and later drained in a similar manner, followed by a well designed freeze-thaw cycling, a plain correlation between the amount of free mica grains in the unbound sub base materials of crushed rock aggregates and frost heave action (in particular noticeable in the residual heave) can be provided.
