Abstract
The disadvantages of traditional hot asphalt mixture were very obvious in repairing damaged asphalt concrete pavements, which was affected by seasons easily and highly construction condition requirement. Therefore, the study on cold patch material for asphalt concrete pavements became so necessary for curing and repairing in time, and insuring traffic smoothly in winner. The developing history of cold patch material was reviewed, and the characters of typical cold patch material at home and abroad were analyzed also in this paper. The main problem and research direction of cold patch material were put forward based on damaged pavements resulted from icing in plateau and humid region, especially, the snowstorm in southern China early in 2008. References were offered for the future research of cold patch material so that improved serve life of highway.
