Reinforced Polyester Paving Mat

Reinforced Polyester Paving Mat

?Delays reflective cracking
?Provides a Moisture Barrier

?Easy installation and Less Maintenance

?Fully Millable and Recyclable

?Low risk of product shrinkage during the overlay process

?Tensile strength, roll length, width and area weight can be tailored according to client’s demand.

Reinforced polyester paving mat has a combination structure of Polyester Mat + Fiberglass Scrim + Polyester Mat. The strong fiberglass mesh embedded into the polyester mat is the key factor to its performance, as reinforced polyester paving mat extends the life of pavement overlays through the delay of reflective cracking. The Reinforced Polyester Paving Mat provides the highest tensile strength at elongation lower than 5%, making it a strong, commercially available and full coverage paving mat or fabric.

The product also serves as an effective moisture barrier equal to paving fabrics and mats. The unique, non-woven, polyester matrix structure of the Reinforced Polyester Paving Mat allows asphalt binder to fully penetrate and fill voids within the fabric, limiting moisture infiltration and preventing water from infiltrating into the granular layers of the pavement structure.

Reinforced Polyester 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. 

Technical data 

Instruction to use the reinforced polyester paving mat:

? Remove dirt, gravel and dust from the pavement to assure good adhesion between asphalt and pavement.
? If the road is damaged, it must be repaired to make the surface of the road hard and smooth.
? For a good result, the asphalt binder that will be used to adhere the reinforced polyester paving mat to 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 Reinforced Polyester Paving Mat must be overlaid onto the hot asphalt before the asphalt lose it’s mobility so as to assure the mat fully soaked by asphalt and effectively provides a moisture barrier.  

?On installation of the Reinforced Polyester 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 Reinforced Polyester Paving Mat:
?Reinforced Polyester Paving Mat must be installed on hot asphalt. We recommend the following asphalt. AC-20; PG64-22; AR8000 +, or the asphalt with penetrate rates 60-80. In extremely hot summer, we recommend to use the bitumen with high viscosity, such as AC-30; PG67-22; AR8000 +, or the asphalt with penetrate grade 40-60.
? The best ratio of asphalt is 1.1 liters / square meters paving mat, but subject to the project site situation during the installation, the ratio can be between 1.0-1.3 liters / square meters. According to different thickness of the Reinforced Polyester Paving Mat, the ratio of asphalt should be adjusted. During the asphalt delivery, we do not suggest to heat the asphalt with a temperature higher than 204 ?, because this would hinder the pre-mature of liquid asphalt.
? Handle the Reinforced Polyester Paving Mat with care during the installation, the paving mat might be damaged or it may cause bad result if the paving mat drop 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 ensure the two layers of paving mat fully soaked by the hot asphalt. Use roller to press the paving mat or use brush to clear out bubble 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 the 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: two layers of paving mat must be overlapped together. In the longitudinal direction the width of overlapped area must be at least 10.2cm, and in the lateral direction, the width of overlapped area must be at least 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 sharp objects on the paving mat; to avoid asphalts sticking to the tire of the machine, do not minimize the ratio of bitumen.
