AI Technical Summary
Technical Problem
Existing bituminous conglomerate additives fail to simultaneously enhance mechanical properties and reduce environmental impact by minimizing raw material usage and carbon footprint.
Method used
A composition combining recycled or virgin thermoplastic polymers, polyvinylbutyral, and graphene, specifically a mixture of polyethylene and polypropylene with polyvinylbutyral and graphene, added to bituminous conglomerates to improve mechanical properties and reduce environmental impact.
Benefits of technology
The additive composition significantly increases tensile strength, stiffness, and fatigue resistance, reducing the rutting phenomenon and extending the service life of road pavements while minimizing material usage and emissions.
