Filament Polyester Geotextile for Road Construction in Bangkok Thailand

Solution

BPM engineer recommended that customers use 300gsm filament non woven polyester geotextile membrane, which can be checked by increasing the tensile strength. Today, after receiving customer information, we provided the customer with a sample of 2 square meters of filament polyester geotextile membrane for free. After the customer received it, the local testing agency in Bangkok conducted some professional testing, and the testing agency confirmed us Quality of products. After confirming the construction area with the customer, as well as some construction details. And after waiting for the customer to pay, we immediately produced 35,000 square meters of filament polyester geotextile membrane. The filament is quickly obtained in the pavement base of nylon geotextile, it needs to maintain its network, while not losing its exempt function to prevent water and soil geotextile, and use it with foundation, soil construction, rock, soil or other materials, and the use of geotextile. The characteristics of soil formation, protection, drainage, isolation, filtration, and containment. Wisdom and other functions have improved the quality of the highway, prolonged the life of the highway, shortened the construction time, and lowered the project cost.

Benefit

Filament polyester geotextile membrane is made by the method of forming and consolidating polyester filaments. Its fibers are arranged into a three-dimensional structure. It is a new type of building material in geotechnical and civil engineering applications. In addition to the characteristics of mechanical strength such as puncture, it also has good vertical and horizontal drainage performance and good extension performance, as well as high biological resistance, acid and alkali resistance, aging resistance and other good chemical functions. Polyester filament geotextile also has a wide pore size range, tortuous void distribution, good permeability and filtration performance. Light weight, good overall continuity, easy construction, high tensile strength and corrosion resistance.

Construction method of polyester filament geotextile

(1) Construction steps: construction preparation→laying liquor asphalt sticky layer oil→laying geotextile→laying asphalt concrete.

(2) Construction preparation: The old road surface should be cleaned of loose dust and debris, cleaned to keep the road dry, and the uneven part of the road surface should be leveled. If the road surface is severely damaged, the structure should be replaced according to the design requirements. Level the road with obvious rutting.

(3) Spread the bituminous sticky layer oil: use liquid petroleum pitch for the sticky layer oil. When spraying, the atmospheric temperature should be above 10℃, and the oil temperature should not be lower than 180℃. Use one spray, and the oil volume is 0.7kg/m. Spray evenly, and the spray width should be 5~10cm wider than the geotextile.

(4) Laying and lap joint of geotextile: The geotextile is manually laid, using single-sided pile polyester filament, weighing about 300g/m2, and the rough side of the pile is facing up, and one side is tightened and fixed. Lay straight and close to the road. The laying of geotextile must be completed before it loses its cohesiveness. After laying, it is rolled with a tire roller to make it tightly combined and the length of the wipe is 10-20cm. The geotextile should be laid in a straight line as much as possible. When it is necessary to turn, cut it at the turning point to avoid wrinkles when laying it over and over.

(5) Laying the asphalt concrete surface layer: After the geotextile is laid, pave the asphalt concrete immediately. In order to make the paver and the transportation vehicle drive, you can sprinkle sand or stone chips on the geotextile, and ensure the asphalt concrete compactness.

(6) Precautions for construction: Geotextiles cannot be stacked in the open air, and there must be fixed rain and sun protection facilities to prevent dampness or aging under ultraviolet light. When laying asphalt concrete, prevent vehicles from turning sharply or braking on the geotextile. It is not suitable for construction when it is raining and humid or the temperature is cold, otherwise the bonding strength will be affected.
