Summary:This study aims for improvements of anti-freezing pavements with physically flexible properties based on the concept of gum-rolled asphalt pavements. By addition of de-icing chemicals into the gum- rolled asphalt mixture, bond-destruction between snow /ice and pavement is prospected to be promoted with not only the physicaly flexible action of pavemenrts under repeated traffic loads but also chemical de-icing effects. As for newly developed anti-freezing pavements, laboratory experiments of physical and chemical properties were carried out. As results of these experiments, though effects of anti-freezing pavements were recognized to some extent, the research subjects of furthermore improvements were clarified.
