METHOD FOR SUPPLEMENTARY CONTINUOUS VIBRATORY FINISH MIXING OF LOW-BALLAST ASPHALT-CONCRETE COMPOSITION

摘要

FIELD: building, particularly to construct asphalt-concrete motor car pavings and other building structures provided with similar coverings.;SUBSTANCE: supplementary finish mixing method involves connecting trailed vibrobunker to asphalt paver so that the vibrobunker is in front of the paver; performing vibrational treatment of asphalt-concrete composition inside the vibrobunker at 19-20 Hz frequency, 1.20-1.21 mm vibration amplitude and 99-119 cm²/c³ vibration intensity for 30-40 s.;EFFECT: decreased binding agent consumption and power inputs for further mix compaction, as well as increased quality of asphalt-concrete layer in road paving.
