What It Is Pavement reclamation is the in place pulverizing of existing asphalt concrete pavement for re–use in the existing pavement structure as a granular base material. The process will normally incorporate a percentage of the underlying granular base material to provide a sound, competent granular material meeting or exceeding the existing bases' performance characteristics.
This process employs the use of an asphalt reclaimer specifically intended for the pulverization of asphalt pavement. The reclaimer is equipped with a milling head containing up to twice the amount of teeth as a pavement profiler, which provides material capable of passing most gradation specifications for 25mm minus base material. .
Reasons For UseThe re-use of the asphalt pavement as base gravel is a recommended option when the removal of the entire layer of pavement is required during the reconstruction of a roadway.
Benefits of the incorporation of the asphalt pavement in the base include the reduction or elimination of haul costs and traffic, dump fees and purchases of virgin aggregates, reducing the depletion of resources, and lightening the load on waste sites. The addition of these materials also increases the structural integrity of the roadway by increasing the granular thickness of the aggregate base.
