With low cost and fast construction, the scientists explained that the log roads were built for temporary use. The main reason for their collapse is frost heave, which occurs when the waterlogged base soil freezes.
Experts developed plans for new drainage structures. In them, the traditional layers were replaced by drainage pipes filled with gravel. This will reduce its consumption and increase the efficiency of roads.
In general, scientists managed to create structures that do not reduce the strength of the roads.
