Binder design for asphalt mixes with reduced temperature: EVA modified bitumen and its emulsions

High energy consumption and environmental risks are both associated to the use of hot asphalt mixes. In response to the need of more sustainable pavements, the modification of bitumen with low melting point EVA copolymers is investigated. Firstly, different modified binders containing EVA with varyi...
