Category:1003 Aggregate for Seal Coats
| MGS Information |
| Current General Services Specifications (MGS) By Subject |
This article establishes procedures for inspecting, testing and accepting aggregates for use in seal coats.
Contents
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.
