1, sprinkle asphalt pavement surface construction with the construction of the asphalt pavement surface treatment of asphalt surface asphalt surface treatment and penetration into two types of asphalt surface treatment is the use of asphalt and fine aggregate layered material paving into a thickness of not More than 3cm of thin pavement surface layer, usually paved with construction,Large garage high end crack repair machine according to the spread of asphalt and spreading the level of mineral aggregate can be divided into single-layer, double and three-tier three, single-layer And the double layer type is a three-layer type part.


    
Three-layer surface treatment of the construction process as follows:


    
Clean up the grassroots, in the surface treatment before construction, should be sweeping the grassroots grassroots, so that the majority of grass-roots exposed material, and to maintain dry; if the overall strength of the grass-roots level is insufficient, you should first be reinforced.


    
Sprinkle through the layer (or sticky layer) asphalt, the first layer of asphalt asphalt to sprinkle cloth evenly, when found after the sprinkling of asphalt blank, missing side, should be immediately filled with spilled into the work, there should be immediately scraping accumulation . Construction should be used asphalt sprinkler spraying asphalt,road loose maintenance equipment the sprinkler length should be coordinated with the ability to spread mineral. Asphalt sprinkler temperature should be determined according to the construction temperature and asphalt label, under normal circumstances, the oil asphalt should be 130 ℃ ~ 170 ℃, coal tar pitch should be 80 ℃ ~ 120 ℃, emulsified asphalt should be spread at room temperature.


    <PSprinkle the first layer of mineral materials: sprinkle the main layer of asphalt, should immediately use mineral sprinkler or into the work of the first layer of mineral materials. Mineral material to spread evenly to achieve a comprehensive coverage of the same thickness, mineral materials do not overlap, do not reveal asphalt,road broken drill tool when the local lack of material or too much office should be appropriate to find or clean up.
