摘要：

A new technique to extend the service life of bridge decks, by reducing freeze/thaw damage through the incorporation of phase change materials (PCMs), has been investigated. The impregnation of two lightweight aggregates (LWAs) with four different PCMs was quantified, and compressive strength, isothermal calorimetry, and thermal property analyses were used to determine the effects of PCM incorporation on the physical properties of mortars. Physical and thermal property data were used to refine a previously-developed model and determine locations in the United States where PCM incorporation to reduce freeze/thaw damage may be a viable technology.
