The role of the road surface seal can be summarized as 4 points: closed a layer of water and water play a role; grass and asphalt surface layer between the transition and effective coupling effect; a layer of the surface of the road was destroyed, isolated loose reinforcement Strong; in the asphalt pavement before the grass-roots to temporarily open the traffic to prevent grass-roots due to weather (such as rain, winter, etc.) or vehicle damage.
Seal can be divided into the top seal layer and under seal layer. On its construction type to points, can be used mixing method or layer of single-layer surface treatment; can also be used asphalt emulsion slurry seal. For thermal spray asphalt, coal asphalt or thermal spray modified asphalt, the requirements of petroleum asphalt temperature of spray 130 �� ~ 170 ��. Coal tar pitch should be 80 �� ~ 120 ��, it is appropriate to use asphalt sprinkler and granule withdrawal cloth machine joint operation. Aggregate specifications according to design requirements, construction methods and other emulsified modified asphalt construction method is consistent.Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery
