This guidance establishes procedures for the inspection, testing and acceptance of aggregate for
drainage.
Contents
1009.1 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 if material has never been tested before.
- (b) Source Approval. Must meet 1002 quality as required in EPG 1001.4.2 General Requirements for Material - Source Approval Samples.
1009.2 Acceptance
Acceptance is based on routine tests in the field to ensure compliance with the requirements of Sec 1009. 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.
1009.3 Records and Reports
All plant records shown in EPG 1001.6 General Requirements for Material - Records and Reports shall be maintained. The material shall be reported through AASHTOWARE Project (AWP) in accordance with AWP MA Sample Record, General.
1009.4 Laboratory Testing for Sec 1009
1009.4.1 Types of Samples Tested
1009.4.1.1 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.
1009.4.1.2 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 AWP.
1009.4.1.3 Production Sample
Tests consist of sieve analysis 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 AWP.
1009.4.2 Procedure
1009.4.2.1 Sieve Analysis
Aggregate shall be tested in accordance with AASHTO T 27.
1009.4.2.2 Specific Gravity and Absorption
Aggregate shall be tested according to AASHTO T 85 for specific gravity.
1009.4.2.3 Los Angeles Abrasion
Aggregate shall be tested in accordance with AASHTO T 96.
1009.4.2.4 Deleterious Content
The percentage of deleterious substances in coarse aggregate shall be determined according to TM-71, Deleterious Content of Aggregate to meet the quality requirements of Sec 1002. Where field determinations show a total deleterious content of 2.5 percent or less, including not more than l.0 percent mud balls and shale, the deleterious content is to be inspected visually. The sample is to be tested if visual inspection indicates more than 2.5 percent total deleterious material present in the sample. Source approval samples shall always be tested regardless of the content of deleterious material.
1009.4.3 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.
