Crack sealing materials ointment. Construction process is simple, less equipment required, after the material is heated (heated to 120 degrees) water sprinkled with artificial cracks, sprinkle some stone chips can be opened to traffic; widespread use of the material, the use of good, but the disadvantage is mainly used for manual operation, there is a certain security risk.
Construction process is as follows:
⑴Before routine inspection equipment, such as fuel oil deposit boxes, oil level, pipe, hose fittings and parts fastening case. Check everything to be normal, the move to self-construction point.
⑵Traffic construction safety regulations by placing warning signs, construction licensing, road signs facilities to ensure the safety of the construction site and in the past road safety.
⑶Press the road, adjust the slot machines slot width 1CM, depth 2CM, slot machines irregular road surface crack open a uniform groove track.
⑷Use a hair dryer on high pressure high pressure after notching road dust, road dust so after notching sand, no residue of old material, after passing the examination to the next step.
⑸On the one hand the heat gun to remove a wet road surface moisture to form a dry bonding surface; the other hand, the heat generated by the hot air gun can instantly asphalt pavement is heated, softened asphalt concrete pavement surface structure, pouring hot melt material formed in contact with the road surface heat effect, increasing the adhesive material between the road surface and, after passing inspection routine for the next step. (Generally temperatures above 5 ℃, construction under sunny circumstances, without this step)
⑹Operator holding a pouring gun, with the hot air spray gun after pouring. Injection pressure should be chosen when pouring pouring equipment, make sure the seam groove without leaving air.
