This guidance establishes procedures for the inspection, testing and acceptance of aggregate for surfacing.

1006.1 Procedure

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

Samples required for Laboratory tests are as follows:

(a) Initial Evaluation required if material has never been tested before.

1006.2 Acceptance

Acceptance is based on routine tests in the field to ensure compliance with Sec 1006. Samples are to be taken at destination or at the source of aggregate production by MoDOT inspectors at intervals of one per 2,000 tons. For small quantity jobs see Sec 1006.

1006.3 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 SiteManager in accordance with Sample Record General Information Bulldozer.jpg.

1006.4 Laboratory Procedure for Sec 1006

1006.4.2 Types of Samples Tested

1006.4.2.1 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.

1006.4.3 Procedure

1006.4.3.1 Sieve Analysis

Aggregate shall be tested in accordance with AASHTO T 27.

1006.4.3.2 Specific Gravity and Absorption

Aggregate shall be tested according to AASHTO T 85 for Bulk Specific Gravity.

1006.4.3.3 Los Angeles Abrasion

Aggregate shall be tested in accordance with AASHTO T96.

1006.4.3.4 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 4.0 percent or less, including not more than 2.5 percent mud balls, the deleterious content is to be inspected visually. The sample is to be tested if visual inspection indicates more than 4.0 percent total deleterious material present in the sample. Source approval samples shall always be tested regardless of the content of deleterious material.

1006.4.4 Sample Record

The sample record shall be completed in SiteManager, as described in Sample Record General Information Bulldozer.jpg, 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.
