Backfill can also be done using flowable fill, a cementitious material with a low water-cement ratio that is delivered to the job site by a ready-mix truck. Typically, the utility pipe or other equipment in the trench is first covered with an aggregate material, then the flowable fill is placed in the trench directly from the truck, just like regular concrete.

The superheated aggregate is used to heat the RAP materials. The aggregate temperature drops as the RAP material is heated and its moisture evaporated. The recycled mix is brought up to discharge temperature in the last portion of the drum. The parallel flow drum mixers were effectively used for recycling in the '70s and '80s.

Reclaimed asphalt pavement (RAP) can be used as an aggregate in the hot recycling of asphalt paving mixtures in one of two ways. The most common method (conventional recycled hot mix) involves a process in which RAP is combined with aggregate and new asphalt cement in a central mixing plant to produce new hot mix paving mixtures.
