Freezing and thawing of the soil around the culvert is one of the reasons for the distress in soil-steel structures especially in case of pipe arches. Therefore, the effect of the frost action on roads and highways is clearly explained herein and presented as a complete literature survey to which the designers of the soil-steel structures can refer. This study is then applied to analyze the effect of this phenomenon on soil-steel structures and their durability. Also, an experimental model was designed to simulate the loss of soil support around the pipe arch and thus observe and study its effect on the structure. Additionally, an evaluation to the present codes is made from the standpoint of frost action. A few recommendations are presented in this study to avoid the frost action and to overcome the distress. Also, cement-modified soil is proposed to improve the properties of the available soil in the site instead of replacing it with naturally non-frost susceptible soil.
