Glasmac PSA

Glasmac PSA is a polymer coated self-adhesive glass fibre grid used to reinforce existing road surfaces, prior to resurfacing with a bituminous overlay, in order to prevent reflective cracking.

It is also used in new road construction and tie-ins to prevent differential settlement and to reinforce surfacing layers.

The high modulus of elasticity of glass also enables a significant reduction in the thickness of the bituminous layers for a given traffic loading.
