Properties

Sealmac® paving fabric is a nonwoven needle punched polyester geotextile manufactured in accordance with ISO 9001:2008. The high melt temperature of polyester (>250 deg. C) ensures that the geotextile properties are not affected by the application of hot bitumen or asphalt.

Application

The existing pavement surface should be free of dirt, water and loose materials prior to the applications of a tack coat to ensure that an adequate bond is achieved. Sealmac® paving fabric is installed through the use of a dispenser unit supplied by Geofabrics to minimise wrinkles and to achieve an efficient contact to the tack coat. The surface treatment then follows which can either be a sprayed seal application or an asphaltic cement (A.C.) overlay. Sealmac® paving fabric has been used in ports, car parks, bridges along with its traditional use in roads and highways.
