Abstract
The challenge of constructing roads on frozen ground in cold climes has long been acknowledged on a global scale. As a result, particular requirements for pavement materials and structures have been developed to address the special construction and usage conditions for highway pavement. The influence of frozen soil change features on pavement materials in cold places is utilized to research the fluctuation law of subgrade temperature field under cement concrete and asphalt pavements because subgrade and pavement illnesses frequently occur in permafrost locations. The residual tensile strength of regular emulsified asphalt dropped to 50% after 7 days of continuous immersion, while that of high-performance modified emulsified asphalt only reached 75%. However, the residual tensile strength of water-borne epoxy resin emulsified asphalt remained over 90%. Regardless of how smooth or uneven the contact surface is, the results show that water-borne epoxy resin emulsified asphalt has good adhesive qualities. However, the water-borne epoxy resin emulsified asphalt still retained over 90% of its original tensile strength. Regardless of how smooth or uneven the contact surface is, the results show that water-borne epoxy resin emulsified asphalt has good adhesive qualities.
