Regeneration method for asphalt-concrete pavings and apparatus for supplying a regeneration medium for carrying out this method

摘要

The invention relates to a regeneration method for asphalt-concrete pavings in which the optimum ratio between the amount of asphalt concrete and the consumption of the medium for regenerating the properties of the asphalt concrete is determined. The asphalt concrete of the paving is broken. In this method, the actual amount of broken asphalt concrete is continuously measured with the aid of a device (6) for continuous measurement of the actual amount of broken asphalt concrete. A regeneration medium is introduced into the asphalt concrete with the aid of a metering device (11), in which process the optimum ratio between the actual amount of broken asphalt concrete and the actual consumption of the regeneration medium is continuously maintained with the aid of a controller (10) and a device (9) for measuring the actual temperature. The regeneration medium is mixed with the broken asphalt concrete, the whole is distributed over the paving and then compacted. IMAGE
