| Shrnutí: | The research results of polymer-modified bitumen (PMB) based on recycled polyethylene terephthalate for road asphalt concrete are presented. A more efficient and economical technology for the thermochemical destruction of recycled polyethylene terephthalate (PET) is proposed. Efficient compositions of Polymer-
Modified Bitumen with different content of recycled PET with an increased range of plasticity have been developed. Regularities for the influence of the recycled PET concentration in the modifier and in PMB on the plasticity range of the binder have been established. The optimal (from a technical and environmental point of view) content of a modifying additive based on recycled PET at various ratios of polyethylene terephthalate and glycerin in the modifier has been established. Studies of the aging processes’ kinetics of the proposed polymer-bitumen compositions based on recycled PET showed a high structural stability of PMB over time. |
