Paving Fabric Interlayer

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.

Paving Fabric

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.
