Vad; I did find some DOT info on the internet from Minnesota, and it is helpful. Specifically I am hoping to find some table of data illustrating different frost penetrations for different conditions where I might compare to what we experience in this region. Thanks for the feedback.
Living in Northern Maine, we experience deep penetrating frost action as much as 7-10 feet deep, depending on temperatures, soils, moisture content, snow cover, etc. I am looking for information showing different soil types with or without different moisture levels and the depth of frost...
