METHOD OF RECEIVING OF ROCK MATERIAL FOR DEVICE OF ROUGH SURFACE TREATMENT OF ASPHALT COATS, PELLETED WITH PETROLIUM BITUMEN AND AMENDED WITH RUBBER CRUMBS Russian patent published in 2009 - IPC C04B26/26 C08L95/00 

FIELD: construction.

SUBSTANCE: method for receiving of rock material for device of rough surface treatment of asphalt coats, treated with petroleum bitumen, amended with rubber crumbs consists in the following: general fabricated rubber goods residuals or worked out wires are crushed into fractional particles of the size 0.5-0.9 mm, 0.5-0.9 mm in the ratio 5-7% of the volume of the petroleum bitumen are introduced in to the working vessel equipped with a device for stirring of rubber crumbs and petroleum bitumen; mixture of petroleum bitumen and rubber crumbs is stirred within 5 hours - reaching 95-98% dissolving level of devulcanised rubber crumbs in the petroleum bitumen; fractional rock material is prepared, sent into the measuring hopper; from the measuring hopper fractional rock material on belt transporter is provided into a drier drum, where it gets heated up to 165-185°C, whereat fractional particles are dried and heated on the principle of counterflow; from the drier drum dried and heated rock material is proportioned through weight and supplied into the upper part of the mixer; petroleum bitumen amended with rubber crumbs is evenly injected into the blending machine and mixed with fractional rock material, mixture is poured out from the blending machine and slowly cooled.

EFFECT: reclamation of waste of chemical production of worked out rubber wires and other technological rubber goods.
