Precautions for Geotextile construction
Then precautions for Geotextile Construction:
1. First of all, clean the road so that there are no sundries on the road, and clean it with clean water. Repair cracks larger than 0 and 6cm on the pavement. The repair materials can be asphalt concrete, asphalt sand or cement mixed soil according to different conditions.
2. The adhesive layer oil can be sprayed on the pavement by hot asphalt distributor. The oil amount can depend on the oil absorption rate of the pavement. The general amount is between 0, 9-1 and 2kg / m2. The oil number is generally more than 60 asphalt.
3. When laying geotextile, the coiled material shall be placed at a certain height. When the non-woven geotextile is tensioned and straightened, it shall be bonded with the adhesive layer oil, brushed with a brush and rolled with a steel roller.
4. After the fabric is fully combined with the adhesive layer oil, no crushed stone chips are sprinkled on it. The non crushed stone chips are generally melon seed chips or medium coarse sand. The amount of crushed stone chips depends on the oil flashing on the fabric surface, which is generally about 2m3 / km2.
5. When laying geotextile in a large area, it can be fixed with fixer at the transverse lap of geotextile according to the specific situation. Do you know the use value of geotextile?
At the same time, the geotextile shall be kept dry. If it is rained, it shall be dried before laying. When laying geotextiles, construction workers shall not smoke. When the asphalt used to bond the geotextile is cooled, the upper layer shall be made. When the geotextile is saturated and the heat calendar Green has not been cooled, do not drive on it, and do not turn around and brake on the paved geotextile.
