In 2020,China made a clear commitment to achieve carbon peak by 2030 and carbon neutrality by 2060.In 2021,the Office of the Ministry of Housing and Urban Rural Development issued the"Guidelines for Green Building Technology(Trial)",which clarified the overall requirements and goals for green building work,industry transformation and upgrading in the current and future periods.The current high consumption and high emission construction methods in road construction indu.stry have not been significantly reversed,which still lags behind the new development concept of"innovation,coordination,green,openness,and sharing"and the requirements of"dual carbon"goals.Design work is the leader of the entire construction process.In China,road construction is still in a stage of rapid development.Improving the design level of road infrastructure,leading the green and low-carbon development in the construction and operation stages,can be very significant for implementing the overall goal of green construction in China,accelerating the realization of carbon peak and carbon neutrality goals.
