Product Information
A needle-punched nonwoven fabric weighing a minimum of 4.1 oz. per square yard, which, when embedded in a field applied asphalt cement tack coat becomes an asphalt saturated fabric membrane. Properly installed it is a pavement moisture barrier and a stress absorbing interlayer which retards crack reflection and extends pavement life. It is then covered with an asphalt overlay or a surface maintenance treatment such as chip or cape seal. Paving fabric is millable and recyclable.
NOTE: It is recommended to stop milling above the system to retain the benefits of the waterproofing interlayer, or mill completely through the fabric elevation rather than mill exactly at the fabric interlayer. AIA always recommends MicroMilling before placing ANY interlayer. The MicroMilling is to have a finished PICK spacing of 3mm.
