چکیده
Objective . The properties of road bitumen, when interacting with the components building compositions, are always transformed relative to their original properties. Therefore, working materials based on filled bitumen regardless field application, main task is monitor dynamics changes in characteristics and control required direction, as well maintaining such viscosity, flexibility fluidity. purpose work study effect modifying additives various bases (fillers, plasticizers waxes) a bituminous binder evaluate effectiveness contribution formation compositions for construction industry. Method. methodological basis principle structure formation. Experimental studies were carried out using standard special methods. Result. results obtained showed that fiberglass fiber proved be best filler composition. In plasticizers, it was revealed most pronounced positive plasticizing observed from use an extract selective oil purification, which allows you system wide range. It has been established plasticizer polyalkylbenzene effectively regulates composition at negative temperatures, slightly affecting heat resistance. wax show Titan synthetic Viscobit polyethylene evenly distributed volume provide stabilization Conclusion process performing study, analyzing obtained, 3 groups matrix studied. directed regulation systems possible due rational choice type additive-filler. Thus, complex fillings designing possibility regulating normalizing (optimization indicators), obtain economic operational effects.
