Paving Fabric

Stress Absorbing Membrane Interlayer - SAMI
“A high-quality needle punched Non-woven Geotextile that, when installed on a bituminous tack coat, performs as a Stress Absorbing Membranes Interlayer (SAMI) and inhibits the upward propagation of cracks from the underlying pavement into the overlay”. This condition is often referred to as reflective crack control.
Paving Fabric offers optimum tensile strength with high corresponding elongation. This ensures that the saturated Non-woven will absorb stress but still follow the contours of the underlying surface.
Paving Fabric exhibits critical bitumen retention properties that ensures sound adhesion between the old and new surfacing layers. This encourages bitumen to be drawn up from the tack coat and provides for an easy installation that results in a strong bond being developed between the fabric and underlying surface.
Forms a permanent waterproof barrier that prevents moisture or water penetration into the road base from above. This protects the subsoil from water intrusion through the pavement and any subsequent reduction in bearing capacity. The product is available in several widths.
