During the construction of road markings, it is necessary to blow away debris such as soil and sand on the road surface with a high-pressure wind purifier to ensure that the road surface is free of loose particles, dust, asphalt, oil and other debris that affect the quality of the marking, and wait for the road surface to dry.
Then, according to the requirements of the engineering design, the automatic auxiliary line machine is used in the proposed construction section and supplemented by manual operation to put the auxiliary line.
After that, according to the specified requirements, the high-pressure airless undercoat spraying machine is used to spray the same type and amount of undercoat (primer) as approved by the supervising engineer. After the undercoat is fully dried, the marking is carried out with a self-propelled hot-melt marking machine or a walk-behind hot-melt marking machine.
