Some views on research direction of asphalt pavement in permafrost region

Because repeated freezing and thawing of frozen soil occur alternately,many diseases occur more frequently.such asfrost, boil, drum kits,cracking, uneven subsidence and so on. In response to these phenomena, this paper poses some views about road construction in permafrost regions. Research should be in one-way cooling asphalt pavement's materials and structures, overloading asphalt pavement, quality control of asphalt pavement in permafrost, recycling of asphalt pavement,which can greatly improve the asphalt pavement in permafrost.
