No need. According to the information of the query assembly drawing network, milling technology is mainly used to improve the anti-skid performance of pavement and restore the smoothness and cross slope of pavement. According to the relevant standards, it is only necessary to do static pressure for 2 to 3 times with a road roller, and there is no need for road bed shaping. Fine milling and planing construction technology has gradually become an effective means of rapid pavement maintenance and prolonging road service life.
