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. China Paving Mat suppliers
