AbstractAbout the AuthorReferences
Modification of petroleum road bitumen with a copolymer of ethylene with vinyl acetate (CEV) and 3-glycidyloxypropyltrimethoxysilane (epoxy silane) has been implemented. Epoxy silane, being a heterofunctional substance, sews the bitumen with CEV which makes it possible to obtain a non-stratified polymeric-bitumen binder. To optimize the concentrations of epoxy silane and sevylene as well as the time of the combination of components, a three-factor rotatable experimental plan has been realized. As a result, it is established that the optimal content of sevylene is 12 pts. wt., epoxy silane – 3 pts. wt., duration of combination – 4 hr. An optimal BPB (polymeric-bitumen binder) has the following properties: softening temperature is 66°C, penetration at 25°C – 50; penetration index – 2.15, brittleness temperature – 22°C. Stratification is significantly reduced. The NMR spectroscopy method made it possible to establish that the sewing of the polymeric-bitumen binder doesn’t influence on its molecular mobility.
