Mechanical response of hydronic asphalt pavement under temperature–vehicle coupled load: A finite element simulation and accelerated pavement testing study

•Stress concentrations are more likely to occur within asphalt concrete between adjacent pipes in hydronic asphalt pavement (HAP).•Increasing pipe spacing and embedded depth or reducing fluid temperature can alleviate the stress concentration of the HAP structure.•The pipes can enhance the rutting r...
