Aggregate Road Surface Rejuvenation

Status: Complete
Report Date: 04/20/2015

Summary:

Researchers tested a process to reduce the safety and structural problems related to floating aggregate on gravel roads by mixing crusher dust into the aggregate on the road surface. The process can be successful if the crusher dust has adequate plasticity to bind the aggregate and if it can be acquired cheaply enough to be cost-effective.

Final Deliverables:

Aggregate Road Surface Rejuvenation (Report #2015-04)
Blending Fines into Existing Loose Gravel Costs Less Than Regraveling (Research Summary)
