⑴In accordance with the relevant provisions of the construction design, set construction safety signs.
⑵Asphalt mixed with sand material to fill cracks in solid horizontal slit width ≥10mm and remove surface dust and dirt seam. If the dust is thick seam face, you need to seam side brushing CAP, or clean water, but the fracture face pasted road with front seam pressure to keep dry.
⑶Operation Road hot tack pressure seam tape
Depending on the size of the crack, cut cut good pressure seam band size, and press the seam to avoid contamination with adhesive surface. Liquefied petroleum gas flamethrower barbecue joints surfaces, use of waste heat baking pressed seam tape adhesive surface. If the surface is asphalt seam, the seam surface oil spots appear and press seam tape pasted surface becomes slick, press the seam tape to paste in the seam surface; if the seam surface is cement or steel, seam side barbecue relatively long time, spray guns should bring a little farther away from the seam. If the crack along the seam with a turn to the right, just a little left of the seam zone baking, and vice versa. For seam with ending part, seam side grill time should be longer, with the seam after seam pressed against the surface, then bake on both sides of the seam tape to slick. As shown in Figure 6. For less than a single crack crack width 10mm with hot press adhesive tape along the seam side seam pasting Sealing baking process. For small crack, small can be baked after the collapse of the seam zone melt pressure, while baking, while with a spatula to smooth the material level, then sprinkle with a suitable stone tablets.
⑷Sprinkle the road to bring pressure seam less than 3mm sand, wedging effect on fracture can achieve better results.
