,.., . r""I . 337-6 Acceptance of the Mixture. 337-6.1 FC-9.5 and FC-12.5: Meet the requirements of 334-5. 337-6.2 FC-5: Meet the requirements of 334-5 with the following exceptions: 1. The mixture will be accepted with respect to gradation (P-3/S, P-4, and P-s), and asphalt binder content (Pb) only. 2. Testing in accordance with AASHTO T312-04 and FM 1-T 209 (and conditioning prior to testing) will not be required as part of 334-5.1.1. 3. The standard LOT size of FC-5 will be 2,000 tons [2,000 metric tons], with each LOT subdivided into four equal sublots of 500 tons [500 metric tons] each. 4. Initial production requirements of 334-5.3 do not apply. 5. The Between-Laboratory Precision Values described in Table 334-5 are modified to include (P-3/S, P-4, and P-s) with a maximum difference per FM 1-T 030 (Figure 2). 6. Table 334-4 (Master Production Range) is replaced by Table 337-2. 7. The mixture will be accepted on the roadway with respect to surface tolerance in accordance with the applicable requirements of 334-5.8. No density testing will be required for these mixtures. r"J . r'l . .., . .., . ., .

II 337-6.2.1 Individual Test Tolerances for FC-5 Production: In the event that an individual Quality Control test result of a sublot for gradation (P-3/S, P-4, and P-s), does not meet the requirements of Table 337-2, take steps to correct the situation and report them to the Engineer. In the event that two consecutive individual Quality Control test results for gradation (P-3/S, P-4, and P-s) or an individual test result for asphalt binder content does not meet the requirements of Table 337-2, the LOT will be automatically terminated and production of the mixture stopped until the problem is adequately resolved (to the satisfaction of the Engineer), unless it can be demonstrated to the satisfaction of the Engineer that the problem can immediately be (or already has been) resolved. Address any material represented by the failing test result in accordance with 334-5.9.5. . -, . ,., . ,., . 337-7 Special Construction Requirements. 337-7.1 Hot Storage of FC-5 Mixtures: When using surge or storage bins in the normal production of FC-5, do not leave the mixture in the surge or storage bin for more than one hour. 337 -7.2 Longitudinal Grade Controls for Open-Graded Friction Courses: On FC-5, use either longitudinal grade control (skid, ski or traveling stringline) or a joint matcher. 337-7.3 Temperature Requirements for FC-5: 337-7.3.1 Air Temperature at Laydown: Spread the mixture only when the r"'l . .., . ,.., . 09/09 01000-75 03-4122.F .
