If the MDV and density test results are contradictory, initiate an investigation. The CAT 11 shall recommend a plan to the Engineer for resolving the discrepancy based on the results of the investigation. Take corrective action when required by the MDV start-up process of 00745.16(b-1-c). After the requirements of 00745.16(b-1-c) have been met, take corrective action if the MDV test results show that two consecutive running average of four samples are outside the above limits for air voids, VMA, VFA, or P No. 200/Pbe ratio. Document the corrective action and notify the Engineer. If test results continue to be outside the tolerance, stop production and make adjustments. Restart production only after the Engineer has approved the proposed adjustments. If the MDV test results are outside tolerance, but the mixture meets the current requirements for gradation and asphalt content, an adjustment to the JMF targets is required. Do not start a new lot as a result of the adjustment. A request for an adjustment to the JMF targets may be made to the Engineer by the Contractors CAT- II. The requested change will be reviewed and documented by the Engineer. If acceptable, a revised JMF will be allowed. Clearly document the sublot test for which the adjusted targets are in effect. Adjustments for gradation shall not exceed the tolerances specified for the original JMF limits. Adjustments for AC content shall be within 0.5% of the original JN¢. The JNiF asphalt content may only be reduced if the production VMA meets or exceeds the above requirements.

Regardless of these tolerances, the adjusted JNIF shall be within the mixture specification control points of 00745.12. If a redesign of the mixture becomes necessary, submit a new JMF according to the requirements of these specifications. Perform a Tensile Strength Ratio (TSR) test (AASHTO T 283) on a sample obtained during the first two days of production after QC test results verify that HMAC constituents with a weighting factor greater than one according to 00745.95 are in tolerance. Provide test results to the Engineer within four working days of obtaining the sample. Stop production and make adjustments if the TSR is less than 70. Restart production only after the Engineer has approved the proposed adjustments. b.

Obtain a sample during the first 100 tons of production and immediately perform MDV testing. 2. If air voids and VMA are within tolerance, then continue remaining NmV testing at the established random QC sublot interval. If not, then go to step "3". 3. If air voids and/or VNiA are out of tolerance according to 00745.16(b-1-a), then make adjustments and immediately obtain another sample and perform NfDV testing. Go to step "4". 4. If air voids and VMA from the N1DV testing in step "3" are within tolerance, then continue remaining MDV testing at the established random QC sublot interval. If not,go to step 11511 . 2014 ITB—72nd Avenue/Dartmouth Street Intersection Improvements 135 1 P a g e 5. If air voids from step "3" are more than ± 1.5% from the target, then stop production immediately and make adjustments. If they are not, then go to step "6". Obtain approval of the Engineer before restarting production. Begin MDV testing again at step "1". 6. If air voids from step "3" are out of tolerance and 1.5% or less from the target, or the VMA. from step "3" is out of tolerance, then make adjustments and immediately obtain another sample and perform MDV testing. Go to step 114". The initial MDV sample shall be used as the first random QC sublot test. Subsequent MDV samples required due to failure of start-up criteria will be used for a sublot QC test if the sample is taken within 100 tons of the scheduled random QC sample location. If not, the MDV testing shall be performed separate from, and not included in, the random QC testing program. Any required MDV testing will be completed at the Contractor's expense.
