Results of <br />the testing and analysis for the LOT will be made available to the Contractor within one <br />working day from the time the LOT is completed. Verification samples shall be reheated at <br />the target roadway compaction temperature for 1 1/2 hours, reduced to the appropriate <br />testing size, and conditioned and tested as described in 334-5.1 .1. <br />The Verification test results will be compared with the Quality Control <br />test results based on the between-laboratory precision values shown in Table 334-5. . <br /> <br />Table 334-5 <br />Between-Laboratory Precision Values <br />Property Maximum Difference <br />Gmm 0.016 <br />Gmb 0.022 <br />Pb 0.44 percent <br />P-200 FM 1-T 030 (Figure 2) <br />P-8 FM 1-T 030 (Fiqure 2) <br /> <br />If all of the specified mix characteristics compare favorably, then the <br />LOT will be accepted, with payment based on the Contractor's Quality Control test data <br />for the LOT. <br />If any of the results do not compare favorably, then the Resolution <br />samples from the LOT will be sent to the Resolution laboratory for testing, as described in <br />334-5.6. <br />334-5.5.2 Roadway Testing: At the completion of each LOT, the Engineer <br />will determine the density (Gmb) of each core (previously tested by Quality Control) as <br />described in 334-5.1.1 from one randomly selected sublot from the LOT. Results of the <br />testing and analysis for the LOT will be made available to the Contractor within one <br />working day from the time the LOT is completed. <br />The individual Verification test results will be compared with <br /> <br />09/09 <br /> <br />01000-63 <br /> <br />03-4122.F <br />
