The addition of such products to road bitumen significantly improves the adhesive properties of the latter, so, first of all, the resins can be used as components for the production of bitumen that meets the requirements of SOU 45.2-00018112-067: 2011 "Road bitumen modified with adhesive additives". The resulting bitumen will be used in the construction of quality road pavements, commercial modified bitumen emulsions, thin-layer coatings of cast emulsion-mineral mixtures.  Product Description popup.authors Astakhova Olena T.
