Abstract: Asphalt roadbed disease causes each are not identical, the low temperature cracking is the main reason of disease of asphalt pavement, and analyses the causes of cracking of asphalt pavement. Cold regions at home and abroad; Low temperature cracking of asphalt pavement will basically occur, so in our country due to cold weather in winter in north China, have a larger temperature difference between summer and winter season, so the low temperature cracking of asphalt pavement diseases in our country is very common in northern asphalt road engineering. This article mainly analyzes the cracks of asphalt pavement under the condition of low temperature in north China form types and causes of cracking fracture, and puts forward some measures to prevention and control of cracking of asphalt pavement and treatment measures of cracking of asphalt pavement.

Keywords: Asphalt pavement; Low temperature cracking; Causes and prevention
