Safety 6

Recycled Aggregate Products Objective: Granular road base material meeting OPSS 1010 requirements. 7

Sources of Raw Materials - Asphalt Roadways Driveways Parking Lots 8

Sources of Raw Materials – Concrete from Infrastructure Sidewalks Curbs Parking Lots Roadways Bridges Pavers Precast Pipes Concrete Returns and Pond Wash-outs 9

Sources of Raw Materials – Concrete from Buildings Footings Floor slabs Columns Foundations Cinder blocks Needs to be clean 10

Unacceptable Raw Materials Bricks Wood Topsoil Organic Material Plastic Drywall/Gypsum Board Asbestos 11

Quality Control Plan Describes processes for the control, acceptance and documentation of sources of raw material Identify how the sources of raw material are controlled during delivery to ensure they are from a suitable source. Describe the production and physical properties testing (tests and frequency) that are conducted by the supplier to ensure the RCM meets OPSS or owner’s requirements, including the absence of gypsum, gypsum plaster and wall board mix and including a process to control excessive fine particles, RAP and building demolition wastes Describes the retention of all records for a minimum 7 years Describes process to identify and manage non-conforming product 12

Raw Material Source – Minimum Information Place of origin Date received Material received Quantity of material Carrier of product Owner of original product 13

Raw Material Sources – Visual Inspection 14 Inspection upon entering the site and after dumping
