What is the ODOT Material Source Network?
Aggregate material is a generic term used for any earthen material that “adds Bulk” to a construction project. Crushed rock, sand, and gravel are common types of aggregate. ODOT has a complex network of borrow sources, cinder sources and of hard rock or gravel from which aggregate products are derived. Most of ODOT’s owned and controlled material sites are located along highway corridors or in close proximity to them. Though each site is a separate tax lot with a distinct legal description they are all related. They are strategically located along the highway systems, forming a network of sites from which ODOT can obtain needed materials. This complex network serves four primary functions: cost-effective source of materials, 24 hour access for emergency response, reliable supply of quality material for maintenance and construction, and minimization of environmental impacts. This network of material sites is important for reasons other than extraction. Often times in emergency situation
