LCRCC Quality Control
1- General Quality Control Requirements:
LCRCC will develop an approved Quality Control Plan. Hot-mix asphalt for payment will not be produced until the quality control plan has been approved. The plan will address all elements which affect the quality of the pavement including, but not limited to:
a. Mix Design. |
 |
 |
2- Testing Laboratory:
LCRCC will provide a fully equipped asphalt laboratory located at the plant or job site. ‘The laboratory will meet the requirements as required in ASTM D 3666. Laboratory facilities and all be kept clean and all equipment maintained in proper working condition. The Contracting officer will be permitted unrestricted access to inspect the LCRCC’s laboratory facility, to. ‘Witness quality control activities, and to perform any check testing desired. The Contracting Officer can advise LCRCC laboratory s Engineers in writing of any noted deficiencies concerning the laboratory facility, equipment, supplies, or testing personnel and procedures. When the deficiencies are serious enough to adversely affect test results, the incorporation of the materials into the work ball be suspended immediately and will not be permitted to resume until the deficiencies are corrected.
3- Quality Control Testing:
LCRCC will perform all quality control tests applicable to these specifications and as set forth in the Quality Control Program. The testing program will include, but will not be limited , tests for the control of asphalt content, aggregate gradation, temperatures, aggregate moisture, moisture in the asphalt mixture, laboratory air voids, stability, flow, in-place density, grade and smoothness. A Quality Control Testing Plan will be developed as part of the Quality Control program.
