Study on the Influence of Frozen Soil Change Characteristics on Pavement Materials in Cold Region
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 influenc...
