Abstract
Abstract Bituminous compositions are provided by mixing 100 parts of an inorganic skeleton or an aggregate with up to 7 parts of bitumen with a first modifier chosen from the group comprising styrene-butadiene polymers, styrene-isoprene polymers, recycled tires or any mixtures thereof, and a second modifier selected from the group comprising polyolefins, polyethylene terephthalate or any mixtures thereof. The present composition allows the utilization of large amounts of recycled plastics.
