Title of the articleResearches of physical and mechanical properties macadam asphalt concrete on the basis of the polymer-bitumen binders
Abstract.In Russia and abroad at the device of coverages of roads of high technical categories a more wide use is found by macadam bituminous concretes. Advantages of these materials are conditioned by their specific transport-operating indexes, such as, safety and comfort of movement, to the resistibility to the external loading and longevity. Application of macadam mixtures in wide scales will allow considerably to improve quality and their longevity travelling coverages. At introduction of polymeric additions to the bitumen, the binder acquires elastic properties i.e. capacity for renewal of primary sizes and form after the removal of loading, the temperature interval of capacity broadens. As a result of undertaken studies of polymer asphaltic concrete type A and macadam-mastic bituminous concrete is shown efficiency of their modification by additions of polymers. Undertaken studies of indexes of properties of bituminous concretes of type A and macadam-mastic bituminous concretes of brand 20 with the use of polymer-bitumen binders showed that all values excelled the analogical indexes of properties of bituminous concretes on an initial bitumen.
Keywords.highway, bitumen, polymers, polymer-bitumen binders, bituminous concrete, macadam-mastic bituminous concrete.
