  • product description:

    Polyester fiberglass cloth is a new glass fiber composite anti-crack material, which is a composite geosynthetic material composed of 60% glass fiber and 40% polyester fiber. This unique combination provides the strength of fiberglass and the flexibility of polyester without the disadvantages of the raw material.

    Fiberglass-Polyester Paving Mat (Fiberglass-Polyester Paving Mat) is a new type of composite geosynthetic material developed after geotextiles, geogrids, and strip polymers. It has good compatibility with asphalt mixture. Engineering practice shows that the glass fiber grid has no waterproof function, and its grid can form an embedding effect with the asphalt mixture, but it is difficult to fix it in use, and it is easy to expand and not conform, which affects the normal paving and reinforcement of the asphalt mixture ; Geotextiles can prevent water seepage, but when the temperature of hot asphalt mixture paving exceeds 160 ° C, the strength and creep resistance of geotextiles are poor and cannot exert the effect of reinforcement and crack resistance; while polyester fiberglass cloth overcomes the disadvantages of both. It is effective in treating pavement cracks and water damage to bridge decks and pavements.

    Features and advantages

    ● Delay reflective cracks

    Reflective cracks will appear within a few months on the pavement that does not use polyester fiberglass cloth. Due to its low elongation and instantaneous tensile strength, polyester fiberglass cloth can effectively eliminate the stress concentration at the junction or crack of the road surface. Reducing the expansion and upward reflection of cracks in the pavement can delay the generation of reflective cracks and prolong the service life of the road, thereby greatly reducing the cost of repair and maintenance.

    ● Provide super waterproof layer

    Installing a waterproofing layer under a hot mix asphalt pavement is one of the best ways to protect and extend the life of your road. The anti-crack cloth of general materials will be deformed and damaged at high temperature, and the polyester fiberglass cloth is made of non-woven glass fiber/polyester. It can withstand the high temperature construction of modified asphalt concrete. The high-temperature stability of the polyester fiberglass cloth will provide a continuous, non-deformable waterproof layer for the pavement, effectively prevent moisture penetration, and avoid damage to the pavement layer and the base layer caused by moisture penetration.

    ● Can be completely shredded and used for road regeneration

    The material properties of polyester fiberglass cloth itself determine that it can be crushed and recycled. When milled, the polyester fiberglass cloth is crushed into very small fibers. This can actually improve the performance of recycled materials. Ripstops of other materials can sometimes stick to milling machines, causing costly downtime.

    ● no shrinkage

    Polyester fiberglass cloth keeps no deformation and no shrinkage under high temperature construction environment.

    ● does not stretch

    Polyester fiberglass cloth will not stretch and deform during construction and installation.

    ● High temperature resistance

    Polyester fiberglass cloth can withstand high temperatures of up to 258 degrees Celsius, so it will not melt or become brittle when paving asphalt concrete.

    Instructions for use - according to the following method of construction, it is very convenient to lay polyester fiberglass cloth.

    ◆ Carry out cleaning work on the road surface to be paved with polyester fiberglass cloth: remove dirt, gravel and dust, and ensure the bonding effect of asphalt.

    ◆ When there are large cracks (more than 6mm), pits or damages on the foundation road surface, it should be repaired and filled.

    ◆ The bonding oil layer used must be hot asphalt, and emulsified asphalt cannot be used, otherwise the bonding effect of polyester fiberglass cloth will be reduced.

    ◆ The best temperature for bonding asphalt is 163-204℃.

    ◆ After spreading the bonded asphalt, the polyester fiberglass cloth must be paved before the asphalt loses its fluidity, otherwise the cloth body is difficult to soak into the asphalt and the waterproof performance of the polyester fiberglass cloth will be reduced.

    ◆ The ambient temperature for laying polyester fiberglass cloth must be above 4°C.

    In order to achieve the best results, pay attention to the following aspects when paving polyester fiberglass cloth:

    ◆ Polyester fiberglass cloth must be installed on hot asphalt. We recommend the following asphalt. AC-20; PG64-22; AR8000; Use asphalt with relatively high viscosity, the following asphalt is more suitable for summer construction: AC-30; PG67-22; AR8000; or asphalt with a puncture grade of 40-60.

    ◆ The optimal ratio of asphalt is 1.1 liters/square meter, but according to the actual situation of the installed road surface and the estimated amount of lamination, the ratio will have a range: 1.0-1.3 liters/square meter. We do not recommend transporting vehicles The bitumen in the tank is heated to above 204 °C, because this operation will hinder the pre-maturation of the liquid bitumen

    ◆ Be careful when loading and unloading the polyester fiberglass cloth. If the cloth roll falls from the transport vehicle, it will damage the polyester fiberglass cloth and cause application problems.

    ◆ If stripes appear during installation, any stripes larger than 2.5 cm in the paving direction must be cut and laminated, and the laminated place must be manually dipped in the asphalt layer. Polyester fiberglass cloth must be used Roll or brush to ensure it is fully in contact with the road surface and remove air bubbles. The width of hot asphalt must be applied to the width of polyester fiberglass cloth plus 4 inches. Polyester fiberglass cloth is not easy to bend on curved surfaces Or stretch. The cloth can be cut short when installing on a curved surface, and can be installed mechanically or manually.

    ◆ The polyester fiberglass cloth can be installed using a tractor or truck dragged mechanism with a metal roller. The function of the metal roller is to ensure that the polyester fiberglass cloth is spread evenly on the road. It must be installed behind the installation roller There is a row of brushes to ensure that the polyester fiberglass cloth is pressed tightly in the asphalt coating. The joints of the polyester fiberglass cloth must ensure that there is a 5.1 cm laminate in the length direction and 10.2 cm in the width direction. layer. The uppermost transverse joint must be along the direction of the pavement, and all joints must be lapped together.

    ◆ When paving machines or other vehicles are turning on the polyester fiberglass cloth, they must be turned gradually, and they must be turned as little as possible to avoid possible damage to the cloth. During the paving construction, the equipment tires must be attached to the cloth surface, and the cloth surface shall be sprinkled with as little sand as possible to avoid being adhered. Do not reduce the amount of asphalt applied to reduce tire adhesion. The best practice is to spread in overlapping areas.

    ◆ The paved road can be open to traffic after being confirmed by the contract party or the installation engineer.
