Aggregate surface material shall not be allowed to remain in ditch lines. Aggregate surface material shall be compacted by operating the hauling and spreading equipment over the full width of each layer of aggregate. Crushed aggregate is to be furnished by the Contractor and shall meet all specifications and the following gradation.

• The above gradation requirements

• The Percent of Wear shall be greater than 40

• The specific gravity to have a minimum of 2.
