Liner for asphalt layers.

摘要

There is described a liner which is particularly employed in the renovation of old bituminous road surfaces as an intermediate layer between the old and new road surface. The liner is a non-woven material containing hollow fibres or consisting of hollow fibres or a composite of such a non-woven material and a woven fabric, knitted fabric, stitch-bonded material or other fabric of defined yarn position. A liner is preferred in which the non-woven material and the fabric of defined yarn position are bonded by the weft-laying Raschel technique. The liner described has particularly advantageous reinforcing and sealing properties and is distinguished by good laying ability.
