Stable and Durable Drainage Geotextile Filter Fabric for Road
Maintenance
Product Introduction
It is a waterproof inter layer by spraying viscous oil reservoir on
flat new pavement semi-rigid stable layer, the old rigid or asphalt
concrete pavement, then mechanically laying singeing geotextile
(roung up), spraying throughed oil,sand, roller rolling,paving
asphalt concrete cover layer and singeing geotextile,pushing the
cracks of subgrade disappear through inter layer stress,avoiding
cracks to extend to the surface, make the road surface to improve
the quality of operation, to extend the use years.
Product Properties
* Reducing then bonding force between the surface and layers.
* Easing the stress concentration among the cracks, prevent the
cracks.
* Being impervious layer after impregnating asphalt, preventing
water to soften the road structure.
* Surface of fiber consolidated by high temperature, the overall
strength improved, make the construction more convenient
* Isolation, filteration, water drainage, protection, stabilization
and strengthen of various roads.
Product Application
* Asphalt paving roads.
* Rivers, lakes, reservoir dams, etc projects.
* Coal ash dams, mine tailings dams,etc projects.
* Airports, railways, roads, tunnels,etc constructions.
