Paving Fabric Interlayers are engineered geotextile fabrics placed
between layers of asphalt concrete (AC). Since 1965, the Paving
Fabric Interlayers have had an outstanding record of improving
pavement performance while reducing maintenance and roadway
Paving Fabric Interlayer Systems extend the life of new AC
pavements and AC overlays. When placed between layers of AC
pavement, these systems becomes an integral part of the roadway
section, forming a barrier to water infiltration and absorbing
stresses to reduce reflective and fatigue cracking of the new
asphalt surface layer
Engineered to provide high strength and high elongation at break to
ensure excellent resistance to damage during construction.
Manufactured from high tenacity UV stabilized virgin polypropylene
or polyester fibers which have been heavily drawn to ensure
excellent long term durability in all soil types.
Manufactured using a randomly orientated web to provide completely
isotropic properties, ensuring that high strength is not limited to
a single direction.
Excellent uniformity with high permeability and low pore size for
Supplied to a maximum width of 6.5mts,ensuring minimum waste over
large construction areas.
100% polypropylene or polyester staple fibers ,needle punched and
random network formation.
UV and rot resistant and biological degradation resistant.
The main reason of above disease is as follows:
1. expand with heat and contract with cold because the temperature
2. ageing of bitumen and elasticity decline of surfacing
3. substrate has crack and horizontal fall head material which used
and construction method ,etc
While the nonwoven fabric can be used in almost any stabilization,
separation or cushioning application , they are most commonly used
in areas that also require filtration. The non woven design of the
material provides a higher rate of flow through, making it easier
for water to pass through the material.
