Relationship Between Pavement Damage and the Combined Action of Frost Penetration and Axle Load
Flexible pavements response is greatly influenced by climatic conditions, and frost penetration in the layered system causes an important increase in bearing capacity. Pavement strengthening during winter is the main reason some agencies allow winter premiums in the transportation industry. However, allowing increased axle loads in winter may have consequences on pavement life, and decision tools could be useful in order to identify the most appropriate conditions for allowing winter premiums. An indoor research facility was used in conjunction with an environmental heavy vehicle simulator to study the complex interaction between axle load, pavement damage and frost penetration. A reference pavement section was used to develop experimental models for bottom-up fatigue cracking and structural rutting, while a second pavement structure was used to validate the models. The pavement response in each structure was tested for various axle load magnitudes as frost progressed in the layered systems. A sigmoidal and a linear model were proposed for bottom-up fatigue cracking and structural rutting, respectively. The proposed models use the concept of relative damage and relative frost depth to quantify the change of pavement damage with respect to combined action of frost penetration and axle load.
