Asphalt crushed stone synchronous seal asphalt is the best amount of asphalt fell to the surface, due to the fluid asphalt surface tension, the hot asphalt along the stone surface upward height of about two-thirds of the height of the stone, and the stone surface to form a Half moon, so that the stone was covered by asphalt 70% of the area of asphalt sprinkling amount. The actual measurement, the use of 10-14mm gravel, asphalt, easy to control the amount of cloth in the 1.5-1.6Kg / m2; use 10-20mm gravel, asphalt, easy to control the amount of cloth in the 1.6-1.7Kg / m2 within. Asphalt spraying, the requirements of asphalt spray should be formed after uniform, equal thickness of the asphalt membrane, to prevent uneven asphalt lead to stone peeling, stripes. Asphalt sprinkle the shape of the rules, linear straight.
Calibration of synchronous gravel seal car. Before the construction, should be synchronized gravel layered car metering system, temperature control system and gravel distribution control system calibration, through the test sprinkle (sprinkle) to determine the amount of asphalt and gravel distribution of the thickness, uniformity, width is Meet the construction requirements, after checking the equipment in good condition before normal use. Synchronous gravel seal car sprinkle (sprinkle) cloth, in addition to two lap aside 10cm set aside stone material, the crushed stone coverage should reach 100%.
Followed by synchronous gravel seal car, keep abreast of the situation. As the original road surface roughness is poor, high road value of large, or mechanical failure, the emergence of small sporadic asphalt film exposed parts, artificial feeding should be timely, as far as possible without gravel overlap, asphalt membrane exposed phenomenon. When the asphalt film exposed to form a wide, should be promptly closed nozzle and material gate, check whether the pressure of the nozzle meet the requirements, whether the door is blocked by large diameter stone.
