1. The geotextile is best to be erected mechanically or manually. When laying, pay attention to make the rough side of the singe face up, and then fix one end with a fixture, tighten it with mechanical or human power, and the tensile elongation rate is about 1. 0% ~ 1.5%. Lay the road ahead.
2. The geotextile horizontal overlap is about 4 ~ 5cm, according to the paving direction, press the rear end under the front end, and cement it with hot asphalt or emulsified asphalt, and fix it with a fixture; the vertical overlap is also about 4 ~ 5cm , You can directly use the bonding oil to dry up. When the overlap is too wide, the interlayer at the overlap becomes thicker, and the bonding force between the surface layer and the base layer is weakened, which may easily cause adverse effects such as bulging, detachment, and displacement of the surface layer. Therefore, the overlapped part should be cut out.
3. Geotextile should be laid in a straight line as much as possible. When turning is needed, cut the fabric at the bend, lay it over and spray it with a sticky layer of oil. Try to avoid wrinkling of the fabric. If there are wrinkles during the laying (wrinkle height> 2cm), you should cut this part of the wrinkles, and then overlap them in the laying direction, and use the sticky oil to transfer them.
4. When the geotextile is laid and sprayed with the second bitumen sticky layer oil and cooled for about 2 hours, the appropriate amount of fine yellow sand should be thrown in time to prevent the vehicle from passing through the geotextile due to the sticky oil of the wheels or Damage, the amount of fine sand is about 1 ~ 2kg / m2.
