Mathematical Modeling of the Various Factors Impact on the Frost Depth of Subgrade Construction

At the beginning of the article, there is presented the model of the Experimental Stand DRETM I created using the software SoilVision on the basis of experimental stand really built in scale 1:1. The core of the article is aimed at monitoring the impact of various factors (change in moisture content of the protective layer, initial temperature of structural layers, frost index, mean annual temperature, course and length of freezing ...) to the change of frost depth of subgrade structure. The conclusion focuses on the assessment of the impacts and recommendations of the most relevant input parameters for further modelling, which should lead in the future to new forms of nomograms for the proposal of a protective layer on various factors of non-transport load.
