9.1.3. Name, telephone number, and c-mail address of the person responsible for quality control at the facility:
9.1.4. The quality control tests to be performed on each emulsified asphalt; and
9.1.5. Name and location of all laboratories performing the quality control tests on the emulsified asphalt that is shipped.
9.2. The supplier’s quality control plan shall include a declaration stating that if a test result indicates that a shipment of emulsified asphalt is not in compliance with the purchase specifications, the supplier shall (1) immediately notify the agency of the shipment in question and immediately notify the receiver of the shipment in question; (2) identify the material; (3) cease shipment until the material complies with the specification; (4) notify the agency prior to resuming shipment; and (5) implement any mutually agreed-upon procedures for the disposition of the material. In the event a mutual agreement is not obtained, the specifying agency shall have the final authority in the decision on specification compliance.
9.3. The supplier’s quality control plan shall describe the method and frequency for initial testing, quality control testing, and specification compliance testing.
9.3.1. Initial Testing—For each grade of emulsified asphalt to be supplied, specification compliance testing (complete testing per either M 140, M 208, or M 316) shall be performed for at least three consecutive lots. A lot may be a fixed batch of material or a specified quantity in a continuous operation (see Note 3). The supplier and the agency shall agree on the lot size. The agency must approve any change to a lot size.
Note 3—If a batch operation is used to produce the emulsified asphalt, a tank may be defined as a lot. The lot size would be the amount of material batched into the tank. If a continuous process (inline blending or a shipment from “live” tanks) is used to manufacture the emulsified asphalt, the lot size may be obtained at random during the production for continuous operations. The lot size shall depend on the production method used and the quantity of the emulsified asphalt produced.
9.3.2. Reduced Frequency of Testing for Speq/lcation compliance—If approved by the agency, the frequency of testing for specification compliance may be decreased if the individual M 140, M 208, or M 316 test result for every sample of the initial testing series is within specification by at least the tolerance of the test method for each of the required test methods. With the approval of the agency, the frequency of testing may be further reduced as long as the individual test results continue to meet the tolerance criterion. If the tolerance criterion is not met, every lot will continue to be tested for the individual M 140, M 208, or M 316 property until three consecutive lots comply with the tolerance criterion.
9.3.3. Minimum Frequency—Specification compliance testing shall be performed at the minimum frequency required by the agency for each emulsified asphalt that is supplied.
9.4. The supplier’s quality control plan shall include a statement indicating that the supplier will prepare monthly summary reports for all quality control and specification compliance tests performed during that period and will submit them to the agency on request.
9.5. The supplier’s quality control plan shall provide an outline of the procedure to be followed for checking transport vehicles before loading them to prevent contamination of shipments. The outline shall include a statement indicating that the transport vehicle inspection report, signed by the responsible inspector, shall be maintained in the supplier’s records and will be made available to the agency on request.AASHTO PP 71-11 pdf download.
