KTTL PP Pavement Fabric
KTTL PP Pavement Fabric is a nonwoven needle-punched made from high quality polypropylene
staple fibres. This pavement fabric is a strong, flexible and dimensionally stable fabric
structure, with optimum bitumen retention capacity. KTTL Pavement interlayer designed to
create a moisture-resistant barrier, retard reflective cracking and stand up to
high-temperature hot-mix designs. The high quality KTTL PP Pavement Fabric, 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,
which is referred tobe a reflective crack control.
KTTL PP Pavement 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 surface, this protects
the subsoil from water intrusion through the pavement and any subsequent reduction in
bearing capacity.
