Polyester Fiberglass Paving Mat
◆ Delays reflective cracking
◆ Provides a Moisture Barrier
◆ Easy installation
◆ Fully Millable and Recyclable
◆ Low risk of product shrinkage during the overlay process
Polyester Fiberglass Paving Mat is produced from the mixture of polyester fiber and glass fiber by wet lay-out process. The combination of glass fiber and polyester fiber is the key to understand its performance. After mixing the two fibers together, this composite mat keeps good features of both fibers and minimizes shortcomings of both fibers.
Strong tensile strength make polyester fiberglass paving mat extends the life of pavement through the delay of reflective cracking. Polyester fiberglass paving mat also serves as an effective moisture barrier. The unique, non-woven, polyester-fiberglass structure of the mat allows asphalt binder to fully penetrate and fill voids within the mat, limiting moisture infiltration and preventing water from infiltrating into the granular layers of the pavement structure.
Polyester-Fiberglass Paving Mat creates innovative solutions to help the paving projects to go smoothly and provides superior performance at airport runway, super highway, parking area and business lots.

Instruction to use the polyester fiberglass paving mat:
◆ Remove dirt, gravel and dust from the pavement to assure good adhesion between asphalt and pavement.
◆ If the road is damaged, the road must be repaired to make the surface of the road hard and smooth.
◆ For a good result, the asphalt that will be used to adhere this composite mat with the road must be hot asphalt, but not emulsified asphalt.
◆ The temperature of hot asphalt should be between 163℃ and 204 ℃.
◆ When the hot asphalt covered the road, the polyester fiberglass mat must be overlaid onto the hot asphalt before the asphalt loses it’s mobility so as to ensure the mat fully soaked by asphalt and effectively provides a moisture barrier.
◆ On installation of the Polyester fiberglass paving mat, the air temperature must be higher than 4 ℃.
In order to achieve optimal results, here we provide some Important Notes on installation of Composite Paving Mat:
◆ Polyester fiberglass paving mat must be installed on the hot asphalt. We recommend the following asphalt. AC-20; PG64-22; AR8000 +, or asphalt with penetrate rates 60-80. In extremely hot summer, we recommend to use the asphalt with high viscosity, such as AC-30; PG67-22; AR8000 +, or asphalt with penetrate grade 40-60.
◆The best ratio of asphalt is 1.1 liters / square meters paving mat, but subject to project site situation during the installation, the ratio can be between 1.0-1.3 liters / square meters. According to different area weight of the Composite Paving Mat, the ratio of asphalt should be adjusted accordingly. During the asphalt delivery, we do not recommend to heat the asphalt above to a temperature higher than 204 ℃, because this would hinder the pre-mature of liquid asphalt.
◆ Handle the polyester fiberglass paving mat with care during the installation, the paving mat might be damaged or it may cause bad result if the paving mat drops from the installation machine.
◆During the installation, if it forms a stripe bigger than 2.5cm in any direction, the stripes must be cut and overlaid, and the two layers of paving mat must be fully covered by asphalt so as to assure the two layers of paving mat fully soaked in the hot asphalt. Use roller to press the paving mat or use brush to clear out bubbles in the paving mat to ensure the paving mat fully adhered to the road. When covering the hot asphalt to the road, the width of asphalt should be 4 inch more than the width of paving mat. Since the paving mat can not be curved, for the winding area of the road the paving mat can be cut into several pieces and be installed to the road manually or mechanically.
◆For the connection of two pieces of paving mat: the two pieces of paving mat must be overlapped together. In the longitudinal direction the overlapped area must be at least 10.2cm; and in the lateral direction, the overlapped area must be at lease 5.1cm.
◆If the installation machine or other vehicles have to drive on the paving mat, it should not turn directions frequently or suddenly so as to avoid damaging the paving mat. Do not scatter sand or other object on the paving mat; to avoid asphalt sticking to the tire of the machine, do not minimize the ratio of bitumen.
