This article establishes procedures for the inspection, sampling and acceptance of aggregate for base material specified in Sec 1007.

1007.1 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.
(b) Compaction Standard
MGS Information
Current General Services Specifications (MGS) By Subject

1007.2 Acceptance

Acceptance is based on routine tests in the field to ensure compliance with Sec 1007. 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.

1007.3 Records and Reports

All plant records shown in EPG 1001.6 General Requirements for Material - Records and Reports shall be maintained. A sample record of aggregate inspection shall be created in AASHTOWARE Project (AWP) in accordance with AWP MA Sample Record, General.

1007.4 Laboratory Testing for Sec 1007

1007.4.1 Types of Samples Tested

1007.4.1.1 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 AWP.

1007.4.1.2 Compaction Standard

Tests consist of sieve analysis, maximum density, optimum moisture and plasticity index. The minimum time required for completion of this test is 5 days from the date received. Test results and calculations shall be recorded through AWP.

1007.4.2 Procedure

1007.4.2.1 Sieve Analysis

Aggregate shall be tested in accordance with AASHTO T 27.

1007.4.2.2 Specific Gravity and Absorption

Aggregate shall be tested in accordance with AASHTO T 85 for specific gravity.

1007.4.2.3 Los Angeles Abrasion

Aggregate shall be tested in accordance with AASHTO T 96.

1007.4.2.4 Plasticity Index

The plasticity index is the numerical difference between the liquid limit and plastic limit of the material.

The liquid limit shall be determined in accordance with AASHTO T 89 Mechanical Method(Alternate).

The plastic limit shall be determined in accordance with AASHTO T 90.

1007.4.2.5 Compaction Standard

Aggregate shall be tested in accordance with AASHTO T 99, Method "C".

1007.4.2.6 Deleterious Content

The percentage of deleterious substances in coarse aggregate is to be determined according to TM-71, Deleterious Content of Aggregate. Where field determinations show a total deleterious content of 5.0 percent or less for Type 1 and 5 base aggregates, the deleterious content may be inspected visually. Otherwise, the sample is to be tested for deleterious content.

1007.4.3 Sample Record

The sample record shall be completed in AASHTOWARE Project (AWP) in accordance with 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.
