Preventing low-temperature cracking involves using binders with better low-temperature flexibility, such as polymer-modified bitumen. Proper mixture design with appropriate aggregates, reducing binder stiffness, ensuring sufficient compaction, and controlling the cooling rate during construction can also mitigate thermal stresses.
