Construction Program Management and Inspection Guide

Aggregate Material Sources
▼ Examine material sources (pits or quarries) for
uniformity of materials, presence of pockets or lenses of
deleterious material, pit operations, supervision, and
other production procedures.
▼ Check on any materials source testing and approvals.
▼ Comment on the uniformity of product.
▼ Document whether the source has been designated by
the STA or selected by the contractor and approved by
the STA.
▼ Verify that appropriate environmental clearances were
obtained.
▼ Inspect processing equipment for compliance with
specifications. If more than one material is proportioned
and mixed into a combined subbase or base material in
order to comply with the specifications, either in a
central plant or by road mixing operations, determine
the types, quality, and proportions of the materials used
and the tests performed to ensure that the specified
proportions are followed and that the end product
complies with the specified requirements.
