Impact assessment of shield construction on asphalt pavement

shields;  asphalt pavement;  breakage;  Risk assessment

Metro tunnels in cities generally choose to pass under the road, so it is inevitable to cause damage to the pavement of urban roads. The various types of damage caused by shield construction of pavement were analyzed, the cost composition of pavement life cycle was discussed, and the evaluation methods and standards of highway asphalt pavement performance were adopted to establish a risk assessment model between the maximum settlement of asphalt construction pavement due to shield construction and its performance indicators and cost loss, and the model application research was carried out.
