This guidance establishes procedures for the inspection and acceptance of coarse and fine aggregate for use in concrete.

Inspection, testing, and sampling will be governed by the instructions contained in General Requirements for Material.

Field tests required are as follows:

**Required Field Tests**
TEST	Template	Template Description
Sieve Analysis	T27	Sieve Analysis of Fine and Coarse Aggregate
Percent Deleterious	SAA001Dx^*	NEWEST Deleterious 1005 C Aggregate
Lightweight particle content, including coal and lignite, in fine aggregate	SAA001Kx*	NEWEST Deleterious 1005 F Aggregate
Absorption	SAA005Ax*	NEWEST Retained AASHTO T85 Absorption for Concrete Aggregate**
Absorption	SAA005Bx*	NEWEST Independent AASHTO T85 Absorption for Concrete Aggregate
Thin or Elongated Particles	SAA001Dx*	NEWEST Deleterious 1005 C Aggregate
^*Test Template numbers have been depicted with a generic ‘x’ as some templates are updated and the last letter in the template name may change. The most current template for a template sequence should contain ‘NEWEST’ at the beginning of the template name.
^**Test For Concrete Masonry accepted by the engineer, approximately 20% of retained samples will be sent to the Central Lab for comparison purposes

Samples required for Laboratory tests are as follows:

(a) Initial Evaluation for coarse aggregate.

(b) Source Approval.

(c) Absorption as received and rodded unit weight (mass).

(d) Source Approval for lightweight aggregate.

Source Approval is based on the results of Laboratory tests. Acceptance is based on routine tests in the field to ensure compliance with Sec 1005.

All plant records shown in General Requirements for Material - Records and Reports shall be maintained. The aggregates shall be reported through SiteManager in accordance with Automation Section AS-3510.
