Key Points of Hot-Melt Pavement Marking Construction Technology
Edge line wear on highways is a common issue that directly affects the adhesion and service life of markings. In thermoplastic marking construction, taking appropriate measures according to different levels of wear is crucial for ensuring marking quality.1. Site Inspection: Assessing Wear LevelBefore construction, evaluate the condition of existing edge markings on-site:- Light wear: The old marking remains intact and adhered to the pavement, with a smooth surface but structurally sound, showing no obvious peeling or detachment.- Heavy buildup or aging: Multiple layers of old marking are accumulated, visibly thick, or exhibit cracking, peeling, or separation from the pavement.For light wear, new markings can be applied directly over the existing ones; however, heavy buildup or aged markings must be removed before repainting.2. Construction Process(1) Removal of Old Markings (Required Only for Thick Layer Wear)Use a milling machine or high-pressure water to completely remove the old m...
