An experimental-statistical model has been developed and optimal conditions for the modification process have been established. Possibilities of using maleic anhydride as a foaming agent for the process of obtaining "foamed" bitumens have been studied. Formation and testing of stone mastic asphalt with the use of bitumen modified with maleic anhydride, including foamed.  Product Description popup.authors Hrynchuk Yurii M. Gunka Volodymyr M.
