Precautions for the use of long fiber polyester tire base fabric

As a kind of geotextile, long fiber polyester tire base cloth needs to pay attention to the following aspects when using:

I. Construction Environment Requirements
Temperature conditions: during construction, the temperature should be within the appropriate range, usually above 5 ℃ is recommended to ensure the construction effect and material performance stability.
Humidity control: Avoid construction in rainy days or when the road is wet, because the wet environment may affect the bonding effect of the polyester tire base fabric and even cause quality problems.
2. base treatment
Clean and dry: Before laying the long fiber polyester tire base cloth, it is necessary to ensure that the surface of the base is clean and dry, free of dust, gravel and other debris. This contributes to improving the bonding strength of the base fabric to the base layer.
Leveling treatment: the sharp and abrupt parts of the base surface should be leveled to avoid damage to the tire base cloth during construction. At the same time, for the damage, depression, broken serious parts, should be repaired and leveling treatment.
III. Laying and Fixing
Laying direction: select the appropriate laying direction according to the engineering needs to ensure that the tire base fabric can give full play to its performance.
Fixing method: During the laying process, the tire base cloth should be fixed on the base layer by appropriate fixing methods. For example, in crack treatment, steel nails with gaskets can be used to fix the tire base cloth on both sides of the crack to ensure a firm bond with the base layer.
Lap treatment: for the parts that need to be overlapped, ensure that the lap width meets the requirements (such as the lap width of the transverse joint is 10~15cm), and use hot asphalt and other bonding materials for bonding treatment to ensure the firmness of the joint.
4. subsequent construction and protection
Follow-up construction: after the long fiber polyester tire base cloth is laid, follow-up construction should be carried out in time, such as paving asphalt concrete surface layer. In the subsequent construction process, attention should be paid to avoid damage to the tire base cloth.
Protective measures: during the construction process and after completion, necessary protective measures should be taken to avoid the impact of mechanical damage, chemical corrosion and other adverse factors. For example, humidity, exposure and high temperatures should be avoided during storage and transportation.
V. Safety and Health
Construction personnel protection: because the long fiber polyester tire base cloth may contain glass fiber and other ingredients, construction personnel in the construction process should wear protective gloves and other personal protective equipment, so as to avoid the fiber into the skin caused by injury.
Fire prevention measures: long fiber polyester tire base cloth belongs to flammable materials, in the construction process should pay attention to fire prevention measures, avoid contact with open fire and high temperature environment.
In summary, the long fiber polyester tire base fabric needs to pay attention to the construction environment, base treatment, laying and fixing, subsequent construction and protection, and safety and health requirements when using. Compliance with these precautions will help ensure construction quality and engineering effectiveness.
