AGGREGATE QUALITY CONTROL/QUALITY ASSURANCE The Aggregate QC/QA Program is designed to allow aggregate producers the respo nsibility for controlling the quality of material they produce and to utilize the quality control information they provide in the acceptance process by the Department. It requires aggregate producers to perform quality control sampling, testing and record keeping on aggregates they ship for use by the Department. I t requires the Department to perform quality assurance sampling, testing and record keeping confirming the performance of the producers ’ control plan. The program and participation requirements are described in the Aggregate QC/QA Program Manual . Participation in this program does not relieve the producer of the responsibility of complying with all requirements of the Standard Specifications . AGGREGATE FOR STABILIZATION 1008 -1 AGGREGATE STABILIZATION
Aggregates consist of crushed stone, crushed gravel, uncrushed gravel or other similar material having hard, strong, durable particles free of adherent coatings. Supply aggregates from approved sources participating in the Department ’s Aggregate QC/QA Program in accordance with Sections 1005 and 1006. Sources will not be approved unless the material has satisfactory soundness and satisfactory resistance to abrasion. Satisfactory soundness will be a loss in weight of not greater than 15% when subject to 5 alternations of the soundness test. Satisfactory resistance to abrasion will be a percentage of wear of not greater than 55 %.
Sampling and acceptance for the determination of gradation, LL and PI will be performed as described in the Aggregate QC/QA Program Manual and the Aggregate Sampling Manual using the versions in effect at the time material is shipped. AGGREGA TE FOR NON -ASPHALT TYPE BASES -1 AGGREGATE BASE COURSE
Aggregate base course material consists of crushed stone, crushed gravel, uncrushed gravel or other similar material having hard, strong, durable particles free of adherent coatings. Provide aggregates from approved sources participating in the Department ’s Aggregate QC/QA Program in accordance with Sections 1005 and 1006. Sources will not be approved unless the material has satisfactory soundness and resistance to abrasion. Satisfactory soundness will be a weighted average loss of not greater than 15% when subjected to five alternations of the soundness test. Satisfactory resistance to abrasion will be a percentage of wear of not greater than 55 %.
Sampling and acceptance for the determination of gradation, LL and PI will be perfor med as described in the Aggregate QC/QA Program Manual and the Aggregate Sampling Manual using the versions in effect at the time material is shipped.
