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 EPG 1001 General Requirements for Material.

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 EPG 1001.6 General Requirements for Material-Records and Reports shall be maintained. The aggregates shall be reported through AASHTOWARE Project (AWP) in accordance with AWP MA Sample Record, General.

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 SM.

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 SM.

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 TM-71, Deleterious Content of 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 AWP, as described in AWP MA Sample Record, General, and shall indicate acceptance, qualified acceptance, or rejection. Appropriate remarks, as described in EPG 106.20 Reporting, 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.
