Development of soundproofing and sound-absorbing bituminous membranes containing recycled materials

Abstract

This paper presents a research activity focused on the development of a range of membranes based on distilled bitumen and polymers, specifically designed for high levels of noise insulation from airborne noise. These membranes can be used in multiple layers products, made by the overlapping of materials both organic and synthetic, and can be integrated into the most widespread construction building systems, and in nautical and manufacturing sectors. The newly developed membranes incorporate recycled materials, placing the research in the context of the European Union Circular Economy Package.
