This article establishes procedures for inspecting, testing and accepting aggregates for use in seal coats.

1003.1 Procedure

Inspection, testing and sampling will be governed by the instructions contained in 1001 General Requirements for Material.

Required field tests required are:

Required Field Tests
TEST Template Template Description
Sieve Analysis T27 Sieve Analysis of Fine and Coarse Aggregate
Percent Deleterious SAA001Bx* NEWEST Deleterious 1003 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.

1003.2 Acceptance

Acceptance is based on routine tests in the field to ensure compliance Sec 1003.

1003.3 Records and Reports

All plant records shown in 1001.2.5 Records and Reports shall be maintained. The aggregates shall be reported through SiteManager in accordance with Automation Section AS-3510.

1003.4 Laboratory Procedures for Sec 1003

1003.4.1 Types of Samples Tested

1003.4.1.1 Initial Approval Sample

Tests consist of specific gravity, absorption, and Los Angeles abrasion. The minimum time required for completion of tests is four working days from the date received. Test results and calculations shall be recorded through SiteManager.

1003.4.1.2 Source Approval Sample

Tests consist of sieve analysis, specific gravity, absorption, Los Angeles abrasion, and deleterious content. The minimum time required for completion of tests is four working days from the date received. Test results and calculations shall be recorded through SiteManager.

1003.4.1.3 Production Sample

Tests consist of sieve analysis, specific gravity, absorption and deleterious content. The minimum time required for completion of tests is three working days from the date received. Test results and calculations shall be recorded through SiteManager.

1003.4.2 Procedure

1003.4.2.1 Sieve Analysis

Aggregate shall be tested in accordance with AASHTO T 27.

1003.4.2.2 Specific Gravity

Aggregate shall be tested in accordance with AASHTO T 85 for Bulk Specific Gravity.

1003.4.2.3 Absorption

Aggregate shall be tested in accordance with AASHTO T 85.

1003.4.2.4 Los Angeles Abrasion

Aggregates shall be tested in accordance with AASHTO T 96.

1003.4.2.5 Deleterious Content

The percentage of deleterious substances in coarse aggregate shall be determined according to General Requirements for Material-Percent Other Deleterious Substances, Clay Lumps and Shale in Fine Aggregate. Where field determinations show a total deleterious content of 2.5 percent or less, including not more than 0.5 percent shale, the deleterious content is to be inspected visually. The sample is to be tested if visual inspection indicates more than 2.5 percent deleterious material present in the sample. Source approval samples shall always be tested regardless of the content of deleterious material.

1003.4.3 Sample Record

The sample record shall be completed in SiteManager, as described in Automation Sec 3510, and shall indicate acceptance, qualified acceptance, or rejection. Appropriate remarks, as described in Reporting Test Results, are to be included in the remarks to clarify conditions of acceptance or rejection. Test results shall be reported on the appropriate templates under the Tests tab.
