Abstract

New method of quality improvement of the polymer modified binder (PMB) was considered in the paper. Testify to the fact that PMB modified by nanoagent is less sensitive to aging, as a result of the processes of peptization asphaltene-resin complexes (ARC) in the structure of the modified binder and the crosslinking with the polymer matrix. It is demonstrated that the nanotubes, (SWCNT or MWCNT) using as a modifier, have effect of crosslinking agent and the inhibitor of the aging process of a PBB. The influence of nanomodified PBB on strength and deformation properties of asphalt concrete is researched. It is found that the application of modified binder in the asphalt concrete mixtures enhances the water resistance of asphalt concrete, heat resistance, and shear resistance.
