AbstractAbout AuthorsReferences
The possibility of modifying the road bitumen by the waste of Selenginsky Cellulose and Cardboard Plant as a component that improves its rheological performance is considered. The most effective way of improving the properties of bitumens is modification by polymers. The chemical interaction of components in the compositions of bitumen-polymer materials provides their homogeneity and stability, and reduces the probability of separation of the composition due to the density difference of bitumens and modifiers. The experimental data confirm the presence of positive technical effect of application of lignin-containing waste to improve rheological properties of road bitumen. The obtained bitumen-polymer material with concentrations of lignin wt%: 2, 5 and 10, and 10 wt% of sulfolignin, makes it possible to adjust the rheological properties of the asphalt binder when used in road construction.
