Get Full Compaction on Full Depth Reclamation
BY AsphaltPro Staff
Of the pavement maintenance methods available, full depth reclamation (FDR) is one that will add crushed aggregate prior to the procedure of reclaiming and remixing in-place.
Forgive the oversimplification, but for this quick tip, let’s summarize: Additives work as stabilizing agents and play a role in the reclaiming and remixing stage of FDR. Those agents will set up and bond, offering the reclaimed layer as a base for an overlay.
To get proper compaction of the base—or reclaimed—layer, you’ve got to get your compaction train mobilized. You want to achieve final compaction of the reclaimed layer within two hours of reclamation (depending on ambient temperatures) to achieve manipulation of the elements. You’ve got to get at the base layer before the stabilizing agents set up and refuse to allow further manipulation.
With your base layer’s best compaction achieved, you’re ready to pave an asphalt overlay.
