Key words: propane-butane mixture, supercritical fluid state, deasphaltizate, solubility, carbonate macadam, impregnation

A comprehensive process for deasphaltizing of heavy oil residue and subsequent
treatment (impregnation using a solvent in supercritical fluid state) of a carbonate
macadam by bituminous compounds (deasphaltizate) is developed. The purpose is to
improve its functionality of the material and, above all, to reduce its water absorption
capacity. The process parameters are specified based on the newly obtained data on
thermal capacity of heavy oil residue and deasphaltizate. The results of the process
experimental realization and characteristics of impregnated macadam, including the
water absorption capacity decreased from 3.6 to 0.54 %, are presented.
