FIELD: construction.
SUBSTANCE: plant comprises a metal heating plate with tubular electric heaters, a bitumen-boiling tank and a hopper for a mineral granulate with dosing gate valves for supply of heated bitumen mastic to the surface of the recovered roof and subsequent sprinkling of granulate. The heating plate is installed on the support frame, where heating rollers are inserted with spring-loaded axles, inside the rollers there are tubular electric heaters coaxially inbuilt. External surfaces of rollers are arranged with a row of circular grooves arranged in adjacent rollers relative to each other in staggered order, and for self-propelled operation the plant is equipped with a reversible electric drive.
EFFECT: increased reliability of recovery works.
