FIELD: road reconstruction works, particularly for reuse of worn out asphalt concrete.
SUBSTANCE: method involves loosening layers of road coating by mill operation; adding bonding material and water to previously grinded material; mixing above components; distributing mixture and compacting mixture. Bonding material is viscous bitumen heated up to working temperature and having penetration from 70 to 200. Bonding material is added to cold mixture of grinded material, powder filler and water during stirring thereof. Relation between bitumen and powder filler is from 1:1 to 1:3. Mixture of bitumen and powder filler is taken in amount of 4%-10% of grinded material weight. The second embodiment of cold road coating regeneration is also disclosed.
EFFECT: reduced cost along with maintaining high strength of asphalt concrete.
