They are researched about the influence of ice-broken performance of granulated crumb rubber amount of admixture, thickness of pavement layer, thickness of ice layer and temperature to granulated crumb rubber asphalt mixture by the method of laboratory simulation test. From the research it is indicated that the closer the granulated crumb rubber approach to upper surface of mixture, the larger the amount of admixture is, the more thickness the surface of granulated crumb rubber asphalt mixture is, the better effect of wiping ice off will be. With the reduction of temperature and increase of ice layer thickness, the effect of wiping ice off through granulated crumb rubber asphalt mixture will weaken gradually.
