The construction steps for applying polyester fiberglass fabric in highway engineering, organized and provided by Hongxiang New Materials Co., Ltd. Hongxiang New Materials Co., Ltd. specializes in product manufacturing and construction guidance. Clean the pavement where the polyester fiberglass fabric will be laid: remove debris, stones, and dust to ensure the bonding effect of the asphalt. When the base pavement has large cracks (greater than 6mm), pits, or damages, it should be repaired and leveled. The bonding oil layer used must be hot asphalt, and emulsified asphalt should not be used; otherwise, the bonding effect of the polyester fiberglass fabric will be reduced. The temperature of the bonding asphalt should be between 163-204℃. The polyester fiberglass fabric must be laid before the asphalt loses its fluidity after it has been spread; otherwise, the fabric will be difficult to impregnate with asphalt, reducing the waterproof performance of the polyester fiberglass fabric. The ambient temperature for laying the polyester fiberglass fabric must be above 4℃. To achieve the desired effect, the following aspects must also be noted when laying the polyester fiberglass fabric: The polyester fiberglass fabric must be installed on hot asphalt. We recommend the following asphalts: AC-20; PG64-22; AR8000; or penetration grade asphalt of 60-80. For high-temperature summer construction, it is recommended to use asphalt with a higher viscosity. The following asphalts are more suitable for summer construction: AC-30; PG67-22; AR8000; or penetration grade asphalt of 40-60. The recommended asphalt usage ratio is 1.1 liters per square meter, but depending on the actual conditions of the installation pavement and the expected overlap amount, this usage ratio can range from 1.0 to 1.3 liters per square meter. We do not recommend heating the asphalt in the transport vehicle to above 204℃, as this operation may hinder the pre-maturation of the liquid asphalt. Care must be taken when unloading the polyester fiberglass fabric. If the roll of fabric falls from the transport vehicle, it may damage the polyester fiberglass fabric, leading to application issues. If stripes appear during installation, any stripes greater than 2.5 centimeters in the paving direction must be cut open and overlapped, and the overlapping areas should be manually impregnated in the asphalt layer. The polyester fiberglass fabric must be pressed or brushed to ensure full contact with the pavement and to remove air bubbles. The width of the hot asphalt application must be an additional 4 inches beyond the width of the polyester fiberglass fabric. The polyester fiberglass fabric is not easy to bend or stretch on curved surfaces. When installing on curved surfaces, the fabric can be cut short and installed mechanically or manually. During the installation of the polyester fiberglass fabric, a tractor or truck with metal rollers can be used to ensure that the polyester fiberglass fabric is laid flat on the pavement. A row of brushes must be installed behind the roller to ensure that the polyester fiberglass fabric is pressed tightly into the asphalt coating. The joints of the polyester fiberglass fabric must ensure an overlap of 5.1 centimeters in length and 10.2 centimeters in width. The transverse joints must be aligned along the paving direction, and all joints must be overlapped together. Paving machinery or other vehicles must gradually expand when turning on top of the polyester fiberglass fabric and must avoid turning as much as possible to prevent potential damage to the fabric. During the laying process, the tires of the equipment must adhere to the fabric surface, and as little sand as possible should be sprinkled on the fabric to avoid adhesion. Do not reduce the amount of asphalt applied to minimize tire adhesion. A good practice is to sprinkle asphalt at the overlapping areas. The completed road can be opened to traffic after it has been confirmed by the contracting party or installing engineer.
