MPG and MPG4

Glass Filament Reinforced Paving Composites

Mirafi® MPG and MPG4 are glass filament reinforced paving composites comprised of fiberglass filament yarn incorporated into a nonwoven polypropylene paving fabric.

Mirafi® MPG is a glass filament reinforced paving composite comprised of fiberglass filament yarn incorporated into a nonwoven polypropylene paving fabric. This composite or reinforced paving fabric combines the excellent reinforcing properties of glass filaments with optimum liquid asphalt retention capacity of a mechanically bonded AASHTO nonwoven paving fabric.

The Difference Mirafi® MPG Paving Composite Makes:

  • Reinforcement: High load-properties at low strain (<3%) appropriate for heavy loaded pavements.
  • Cost Effectiveness: Suitable for full width overlay, local patch and joint repair.
  • Sealing: Moisture cannot penetrate into the road structure.
  • Longevity: Maintenance intervals are considerably extended.
  • Stress Relief: Retards crack propagation from the old surface to the new overlay.
  • Adhesive Bonding: Provides uniform bonding between old and new asphalt layers.
  • Installation: Easily included in asphalt resurfacing projects.
  • Recycling: Can be milled with conventional milling machines.
  • Resistance: Chemically resistant to road salt.

Reinforcement

The synergistic improvement of a total system’s strength created by the introduction of a reinforcing geosynthetic (that is good in tension) into a soil and/or aggregate system (that is good in compression but poor in tension).

Sealing

The use of a coating to create an impervious surface.

Adhesive Bonding

Adhering two different surfaces or materials using an adhesive substrate.

Stress Relief

The stress reduction from a geosynthetic while the system is in a state of constant deformation or load.
