Annotation: There is studied the dynamics of aging of organic binders of the coal origin on the substrates characterized by a chemico-mineralogical composition and porosity (granite, limestone). There has been found out a contribution of the coal road tar into aging by a loss of evaporation mass, a surface sorption of a mineral material (MM) and diffusion into the MM capillary-porous space, aggregation and oxipolycondensation of organic binder components at thermostating for 200 hours at 100 0 С . Phase transformations of the second type and thermo-gravimetric characteristics of tar-binding and asphalt-binding substances were studied by the scanning calorimetry and TGJ methods.
Keywords: dynamics of aging, thermostating, organic binders, mineral material, tar-binding and asphalt-binding substances.
