Estimating the effect of aqueous cationic latex from the class of thermal elastic plastics on the properties of bitumen emulsions

To produce cationic bitumen emulsions, is used, whose penetration not lower than 90 mm-1. Such has a small plasticity interval, which leads to deterioration in its heat resistance at elevated temperatures and narrows the scope of application emulsions based on it. Based review emulsion modification methods, been proposed that involves mixing finished with aqueous latex. The process interaction between bituminous an latex considered. A mechanism for disintegration modified surface mineral materials was proposed. emulsifiers have selected composition phase chosen analysis tension isotherms. influence properties investigated. It established main physicochemical characteristics interphase accept similar values proven introduction quite moderately affects basic physical-mechanical makes it possible change technological parameters when using them. increasing concentration polymer positive effect binder. With increase 6 % softening temperature increases by 16 °C, elasticity 74 %, holding capacity minus 25 °C approaching 100 %. Improving residual binder as result could durability layers roadbed expand their construction repair motorways
