[en] A method of obtaining block material based on asphaltites with good physico-mechanical properties is suggested. Epoxide resin, acrylic acid and asphaltite are included in the composition. The method of hardening is either radiation or radiation-thermal. Radiation structurization takes place at low absorbed doses of 5-10 Mrad. At that the quantity of the product structurizated in the spatial structure does not exceed 30-35%. More complete structurization (75-80%) is reached by subsequent heat treatment. Mechanism of radiation-thermal hardening is studied by IR-spectroscopy
