Low temperature cracking and reflective cracking will be discussed next. More information on the theory and origin of cracking can be found in the literature (Arand, 1996; Jacobs et al., 1996; Rigo, 1993).
12.2.1 Low Temperature Cracking
Low temperature cracking induced by a drop in temperature has been well-documented (e. g., Fabb, 1973; Isacsson et al., 1997; Marasteanu et al., 2004; Tuckett et al., 1969). Cracking of an asphalt course appears when the thermal stress, which increases with a drop in the temperature, exceeds the mixture’s tensile strength. It originates at the surface of the wearing course and advances downward.
An overview of factors influencing the development of low temperature cracking has been presented in the literature (Isacsson et al., 1997). Although binder properties have commonly been regarded as responsible for a pavement’s susceptibility to this type of cracking, there are actually many other, though less common, contributing factors (e. g., the content of voids and mastic).
