Pan, Y. (author), Guo, Hui (author), Guan, Wei (author), Zhao, Yongli (author)Rutting is one of the most common distresses in early damage to asphalt pavements. It can raise the risk of ride safety issues, accelerate pavement deterioration, and increase maintenance costs. To investigate the factors that affect the rutting resistance of asphalt mixtures, internal factors (such as aggregate gradation, asphalt content,...journal article 2023
