Research of the Properties of Bitumen Modified by Polymer Latex

Abstract

There are given the investigation results of bitumen modified with the polymer latex Butonal NS 104 depending on temperature, time and the modifying agent amount, taking into account the manufacturing company BASF recommendations. The carried research has shown the possibility to produce bituminous polymer on the polymer latex Butonal NS basis that meets the Ukraine technological normative documents requirements. On the conducted investigations basis, there have been established the rational parameters of bituminous polymer binding agent production process thus allowing determining the conditions of the polymer latex Butonal NS 104 application under the domestic production conditions. The study found that bituminous polymer bending agent physical-mechanical properties change in the wide limits (by 50–100%) depending on the polymer amount, and the preparation process parameters show the possibility of active regulation of its properties under the particular operating conditions. It is established that bituminous polymer bending agent properties resistance and stability under the high process temperatures influence show the possibility of its sufficiently long-term storage under the production conditions with the original properties keeping.
