Effects of freezing and thawing processes on the mechanical behavior of silty soils stabilized with fly ash

Durability of pavement materials induced by environmental effects, namely, cyclic freezing/thawing action, can have a chief effect on the performance of a pavement structure. Freezing/thawing event is considered to be one of the most harmful actions that can make considerable damage to pavement.Therefore, the planning and analysis of pavements should take account for such seasonal effects. Besides, many studies recognized the importance of evaluating the durability of stabilized aggregate bases and suggested that such effects be carefully considered in the mixture design.
