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…

Flexible pavement damage during spring thaw: A field study using the falling weight deflectometer Open
Spring thaw creates critical performance conditions for pavement networks. The increase of water content in the pavement environment is significant during spring thaw. Combined with poor drainage conditions, material condition variations a…

Pavement strengthening with respect to frost penetration Open
In seasonal frost regions frost action is a major impact factor on pavement deterioration. Normallyfrost damage evaluation has been carried out by visual inspection in late spring in order to separate frostaction related damages from other…
View article: Correction of air freezing index for pavement frost protection design to consider future climate changes
Correction of air freezing index for pavement frost protection design to consider future climate changes Open
In cold regions, climate affects flexible pavement performance, such as frost heave. In the context of a changing climate, air freezing index can no longer be considered as fixed for pavement design. Climate simulations were performed for …
