The paper had showed the diseases rates of different road surfaces,further more,comparative analysis were done to research the representative disease mechanism and had given an appraisal of the surface diseases in permafrost regions.

It showes that the diseases rates of different pavement,further more,comparative analysis are done to research the representative disease mechanism and an objective appraisal of the pavement diseases in permafrost regions is given.
