The article presents a review of low-temperature crack (LTC) developments in asphalt pavements commonly observed in regions affected by cold weather. The cold weather contributes significantly towards the development of these low-temperature cracks (LTCs). Since the 1960s, many studies have been published, proposing various cracking mechanisms. The simplistic reason for the development of cracks in low temperatures is thermal stresses, due to contractions and a drop in the pavement’s strength. However, other factors such as frost action also play a significant role. The impact of frost action on LTCs depends on the type of soil and water/moisture content. In addition to frost action, other factors also contribute directly or indirectly to the development of cracks. A comprehensive review of various types of cracks and their mechanism of development is given in the article. It is concluded that, to develop remedies, it is vital to understand the types of cracks.
