8.2. The supplier shall allow the agency to visit the production and shipping site to observe the supplier’s quality control activities, to inspect the facilities, and to obtain samples for testing.
8.3. The supplier shall submit to the agency for approval a complete quality control plan that complies with the req uirements of Section 9.
8.4. The supplier shall follow the procedures described in the approved quality control plan.
8.5. The supplier shall establish a continuing record for each test required on each emulsified asphalt grade listed in the written request required in Section 8. 1.
8.6. The supplier shall forward to the agency the initial series of test data (Section 9.3.1) for each emulsified asphalt grade listed in the written request required in Section 8.1. The supplier shall also obtain and provide a split sample for the agency if requested.
8.7. The supplier shall submit to the agency all reports required by this standard in a form approved by the agency.
8.8. The supplier shall maintain a satisfactory record of compliance with the governing specifications.

9.1. The supplier’s quality control plan shall identi/y the Iöllowing:
9.1 .1. Facility type (e.g., refinery, terminal, production site);

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 —lf 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.AASHTO R 77-16 pdf download.
