Environmental aspects of bitumen modification
Keywords:bitumen, additives, PET, emulsion-mineral mixtures, bitumen-mineral mixtures, modifier, plastic and polymer waste
The paper reflects the relevance of recycled materials and various polymer waste, provides information on the amount of plastic waste and the main directions of recycling and disposal. The paper outlines the ways to introduce additives in road bitumen during the plastic waste recycling, both domestic and industrial production. The paper provides the methods for bitumen modifications which becomes more resistant to aggressive environmental conditions and obtains new improved properties such as a lower temperature of embrittlement, a higher temperature of softening, and consequently, a higher resistance to cracking and shear stability of asphalt concrete.
