Characteristics of Heat treated Polyester Continuous Filament Needled Punched Geotextile:
High strength、good capacity of anticorrosion、big frictional coefficient、small elongation、good capacity of thermal endurance and infiltration.
Application of Heat treated Polyester Continuous Filament Needled Punched Geotextile:
Specialized for asphalt surface paving, Heat treated Polyester Continuous Filament Needled Punched Geotextile are mainly used in new road construction and the old road repairing. When paved under asphalt road or concrete road surface, its funtions as reinforcement, protection, separation and drainage, and prevents the road from reflection crack. In construction course, sticky truck tyre should be keep free from geotextile layer in order to not destroy the geotextile.
