Effect of Aging and Moisture Damage on Fatigue Cracking Properties in Asphalt Mixtures

Recently, damage to asphalt pavements in South Korea has increased because of direct and indirect factors caused by abnormal climatic changes, such as torrential rains, prolonged heatwaves in summer, and heavy snowfall in winter. Additionally, the use of medium and heavy vehicles is also a contribut...
