2019-5-10  Transverse cracking of asphalt pavements normally follows a sigmodal-shaped curve with service time. Thermal crack lengths with time of some pavement sections in the freeze regions showed step-wise characteristics, indicating that a critical crack increment occurs due to a sudden temperature drop with little thermal fatigue behavior.
