Water-Mineral Suspensions for Repair Bituminous Pastes

The optimal emulsifier (zeolite) for the preparation of bitumen pastes was selected, the main mineral of which is clinoptilolite, which has both an external and internal adsorption surface, provides both high hydrophilicity and low water demand of the zeolite, which makes it possible to obtain homogeneous viscous suspensions with a low water-solid ratio for bitumen pastes. The viscosity ranges of the water-mineral suspension necessary to obtain bituminous paste for emulsifiers of various nature and dispersion have been determined. It is shown that the zeolite-containing rock (ZSP) has the lowest water demand among the selected emulsifiers. The influence of the water-reducing effect of the plasticizer on the structure of bituminous pastes has been established.
