TechPave is a nonwoven paving fabric manufactured from high quality polypropylene staple fibres. The fibres are mechanically bonded through needle-punching with heat treatment on one side to form a strong, flexible and dimensionally stable fabric structure, with optimum bitumen retention capacity.
TechPave is a strong layer of fabric is applied under asphalt to minimize surface water infiltration and prevent existing cracks in the road from surfacing to enhance the performance of pavement.
The Barrier function refers to the prevention of fluid movement across the plane of the geotextile. A nonwoven geotextile provides a barrier function when saturated with an impermeable material,like bitumen.
Stress relieving membrane
Retards the propagation of cracks
Reduced the required design overlay thickness
Extends the life of the overlay and the pavement section
Asphalt overlay on flexible pavement
Asphalt overlay on rigid pavement –a layer of DBM/BC should be provided on rigid pavement before laying the TechPave
