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.

Key Features

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.

Functions

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.
