Abstract
Equipment and process for recycling bituminous macadam dug up during repairs to roads and pavements. The pieces of asphalt which were originally compacted are collected up by a transporter, weighed and put in a rotary drier to which is added between 0.5 and 5% of either hot or cold liquid bituminous binder, depending on the weight of the material. This is then mixed together, heat being applied when necessary. The equipment forms a single unit consisting of the weighing machine, the drier, a vat containing the liquid binder and apparatus for measuring out of the amount of binder and injecting the appropriate amount into the rotary drier.
