The good behaviour of asphalt reinforcement depend on 3 conditions :

High quality resin to protect the glass fibers from damage by site plant during installation.
Wide apperture gives excellent bond and removes potential of creating a slip plan.
Higher elasticity modulus significantly higher than that of asphalt.
Appropriate mechanical resistance.

High quality bitumen emulsion and good rate of spread.

Installation process following installation instruction to insure the bond with the overlay.
