Adhesive waterproofing prefabricated SAMI road geocomposite membrane made from highly modified bitumen, designed to act as a reinforcing, anti-pumping and anti-cracking interlayer. POLYSTRADA SA V has been designed and produced to provide a waterproofing contribution and allow stress in the pavement structure to be relieved/absorbed. This membrane is an innovative solution for reinforcing asphalt structures and replaces reinforcing mesh or other traditional systems (SAMIs, geotextiles, etc.) in the construction of new road pavements and maintenance work. POLYSTRADA SA V is an elastomeric prefabricated geomembrane comprising a dual self-adhesive elastomeric bituminous compound, with a woven glass fleece carrier providing excellent dimensional stability and elastic properties resulting in resistance to static and dynamic loading. It is suitable for waterproofing (to address the problem of pumping), as a barrier to crack propagation, and for reinforcement and load distribution on road pavements, even where the asphalt structure requires rehabilitation with relatively non-invasive maintenance work. POLYSTRADA SA V comes with the upper face finished with aggregate to allow for road construction equipment to be operated and driven over the treated surface without any problem. POLYSTRADA SA V is part of the family of products incorporating ADESO technology, an innovative self-adhesive compound that delivers excellent adhesion to all surfaces along with remarkable longevity. The bond is strengthened further by the heat of the asphalt pavement and under the effect of traffic and sunlight.Its self-adhesive properties mean POLYSTRADA SA V retains all its original properties, as the membrane is cold applied, without the need for torching.
