The possibility of using maleic anhydride as a foaming agent to produce foamed bitumen was investigated. optimal content determined according the indicators growth binder volume and half-life foam. With use agent, obtained, later used obtain two samples stone mastic asphalt, which differed in mixing compaction temperatures asphalt mix. For comparison, composition mix designed non-foamed (BND 70/100 BND modified with anhydride) at different temperatures). Stone specimens were formed tested
