Keyjoint Fibre was developed as a quick low cost stress
absorbing joint treatment in response to the ever-increasing problem of
joints cracking. The Keyjoint Fibre uses a specially modified bituminous
binder, which incorporates high PSV aggregates. The material initially
fills in the cracks, and also holds in place the glass fibre strands.
Areas where Keyjoint can be used:
Flexible Pavements
Concrete Pavements
Prior to asphalt overlay
Prior to surface dressing
Where reflective cracking has already occurred.
