General - Perform MDV testing on projects with Level 2, Level 3, or Level 4 dense graded HMAC. Perform MDV tests on every sublot and as required at start up according to 00745.16(b-1-c) and the MFTP. Perform gradation and asphalt content testing with each MDV test. Calculate the following values for each MDV test.
The running averages of four MDV results shall be within the limits given below: Average of Limit Air Voids 4 samples JMF Target 1.0% VMA 4 samples 11.5 - 17.0 (1" Mix) 12.5 - 17.0 (3/4" Mix) 13.5 - 17.0 (1/2" Mix) 14.5 - 17.0 (3/8" Mix) VFA 4 samples 65 - 75 (3/4" and 1/2" Mix in Level 2, 3 and 4) 65 - 78 (3/8" Mix in Level 2, 3 and 4) 70 - 80 (1/2" and 3/8" Mix in Level 1) Passing No. 200 / Pbe 4 samples 0.8 - 1.6 The CDT shall provide the results from the initial control strip to the CAT II for evaluation and comparison with the MDV results. If the MDV and density test results are contradictory, initiate an investigation. The CAT II 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 Contractor’s 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 JMF. The JMF asphalt content may only be reduced if the production VMA meets or exceeds the above requirements. Adjustments for RAP content shall be within 5% of the original JMF, but shall not exceed the requirements of 00745.03. Regardless of these tolerances, the adjusted JMF 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. Laboratory Compactor Selection - Use a Gyratory compactor for MDV when a Gyratory compactor is used to develop the JMF. For all other cases, use a Gyratory compactor or Marshall compactor, as selected by the Contractor. c. MDV Requirements at Start-Up - Perform MDV testing at the start-up of the JMF production according to the following process: 1. 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 MDV testing at the established random QC sublot interval. If not, then go to step "3". 3. If air voids and/or VMA are out of tolerance according to 00745.16(b-1-a), then make adjustments and immediately obtain another sample and perform MDV testing. Go to step "4". 4. If air voids and VMA from the MDV testing in step "3" are within tolerance, then continue remaining MDV testing at the established random QC sublot interval. If not, go to step "5". 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 "4". 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. Add the following subsection: 00745.16(b-3) MDV for Open Graded HMAC - Adjust asphalt content and gradation targets for open graded HMAC during production as directed. The Engineer will document the sublot test for which the adjusted targets are in effect. 00745.24(a) Steel-Wheeled Rollers - Replace this subsection with the following subsection: (a) Steel-Wheeled Rollers - Provide steel-wheeled rollers with a minimum gross static weight as follows: Level 1 and Level 2 Level 3 Level 4 Breakdown and Intermediate 8 ton 10 ton 12 ton Finish 6 ton 8 ton 10 ton 00745.24(b) Vibratory Rollers - Replace the fourth bullet of the first group of bullets and replace the first bullet of the second group of bullets with the following bullet:

Do not deliver the HMAC directly into the paving machine for wearing courses where the continuous length of the panel is greater than 500 feet. Deliver the HMAC to the paving machine by either a windrow pick-up machine or an end-dump transfer machine. 00745.49(b-1) General - In the paragraph that begins "Compliance with the density...", replace the sentence that begins "Use the MAMD method..." with the following sentence: Use the MAMD method of compaction measurement. Replace the paragraph that begins "For Level 3 and Level 4..." with the following two paragraphs: For Level 2, Level 3, and Level 4 mixes, construct a control strip at the beginning of work on each JMF on the project according to ODOT TM 306. The purpose of the control strip is to determine the maximum density that can be achieved for the JMF, paving conditions, and equipment on the project. Additional control strips are necessary when there is a change in compaction equipment or when JMF targets are adjusted according to 00745.16(b-1-a). The Engineer may waive the control strip for irregular areas or areas too small to establish a reasonable roller pattern. Stop paving if three consecutive control strips fail to achieve the specified density. Take all actions necessary to resolve compaction problems. Do not resume paving until allowed by the Engineer. 00745.49(b-4) Control Strip Method - Delete this subsection. 00745.49(b-5) Test Results - Renumber this subsection to b-4. 00745.49 (e) Other Areas - Replace this subsection with the following: 00745.49 (e) Other Areas - Compaction to a specified density will not be required on temporary surfacing (see 00745.50), guardrail flares, mailbox turnouts, road approaches, pavement repair, areas within three feet of back face of retaining walls and areas of restricted width (less than 8 feet wide) or limited length, regardless of thickness.

Perform smoothness testing under the supervision of the Engineer with equipment furnished and operated by the Contractor at the Contractor’s expense. Complete all required smoothness testing no later than seven calendar days following final completion of all travel lane paving on the Project. The Contractor accepts the risk that the smoothness may be affected by exposure to traffic between the date the travel lanes are paved and the date the smoothness testing is completed. If the Contractor elects to perform smoothness measurements on a day other than the day the pavement is placed, additional traffic control required for smoothness measurement, and not required for other work, will be at the Contractor's expense. Add the following subsection: 00745.72 Smoothness Testing Equipment - Furnish all equipment and supplies for determining smoothness. (a) Straightedge - Provide one 12 foot straightedge. (b) Profilometer - Provide a profiling device that employs an accelerometer established inertial profiling reference and a laser height sensing instrument to produce a true profile of the pavement surface. The device shall be capable of reporting elevations with a resolution of 0.004 inch or finer at an interval of 6 inches or less. The unit must also be able to generate the equivalent California-type profilograph plot and values according to ODOT TM 770 as well as the locations and heights of bumps and dips as required in this specification. The profilometer shall be calibrated, in good working condition, and ready for operation prior to performing smoothness measurements. Provide competent and experienced operator(s) for the equipment. The profilometer operator shall meet with the Engineer at a mutually agreed upon time prior to beginning smoothness measurements to discuss all aspects of smoothness measurement on the project. Add the following subsection: 00745.73 Smoothness Testing and Surface Tolerances - Test according to the following: (a) General - Test the base course with a 12 foot straightedge as directed. Test the wearing course with the selected profilometer and provide a profilogram trace according to ODOT TM 770. Price adjustment for smoothness will be made according to 00745.96. Before performing smoothness measurements on the Project, verify horizontal and vertical calibration of the profilometer according to the manufacturer’s recommendations and run the machine twice over a 0.1 mile section of pavement with repeating results. The calibration shall be considered acceptable when the difference in Profile Index between consecutive test runs is 0.3 inches per mile or less. Provide documentation to the Engineer verifying that the calibration and test runs have been successfully completed. After starting paving, perform horizontal and vertical calibration checks at the frequency recommended by the manufacturer. (b) Base Course Surface Test: (1) Transverse - Test with the 12 foot straightedge perpendicular to the centerline, as directed. The pavement surface shall not vary by more than 1/4 inch. (2) Longitudinal - Test with the 12 foot straightedge parallel to the centerline, as directed. The pavement surface shall not vary by more than 1/4 inch. (c) Wearing Course Surface Test: (1) Transverse - Test with the 12 foot straightedge perpendicular to the centerline, as directed. The pavement surface shall not vary by more than 1/4 inch. (2) Longitudinal - Run the profiling device over traffic lanes for the full length of the Project and 50 feet beyond the Project ends to provide a complete graphic profile. Obtain profiles on the pavement surface in the right-hand wheelpath of the travel lane along a line parallel to centerline. Take the profile on transition areas of entrance and exit ramps, as close to the right hand wheelpath of the through travel lane as practical. Profiles shall initially be analyzed by the Contractor according to 00745.73(d), and the profiles and results given to the Engineer no later than eight calendar days following final completion of all travel lane paving on the Project. Individual deviations exceeding 0.03 foot shall be addressed according to 00745.75(c). Provide an electronic copy of all raw profile data files for the Project to the Engineer at the conclusion of the Project. Also provide an electronic copy of International Roughness Index (IRI) data in ERD format (as defined by Engineering Research Division, University of Michigan Transportation Research Institute) to the Engineer for the same pavement sections tested for Profile Index. Provide the data on floppy disk or CD at the conclusion of the Project. This data will be used for smoothness specification research purposes. (3) Transverse Joints - Test with the 12 foot straightedge parallel to the centerline, as directed. The pavement surface shall not vary by more than 1/4 inch. (d) Determination of the Profile Index: (1) General - Determine the profile index in 0.1 mile segments and partial segments. Segments shall begin 13 feet into the Project and run consecutively in either the direction of travel or the direction of HMAC placement, as determined by the Engineer. A segment will end as a partial segment and a new segment will begin when the segment sequence is interrupted by stage construction or by profiled areas excluded from the smoothness requirements. The following profiled areas of pavement are excluded from smoothness requirements:
The party responsible for Project surveying shall locate excluded areas prior to smoothness measurement. Areas excluded from longitudinal profile measurement shall meet the straightedge requirements of 00745.73(b-2). (2) Method of Analysis - Determine the profile index and individual deviations exceeding 0.03 foot by analyzing the profile charts according to ODOT TM 770 and provide the profile charts and results to the Engineer for review. Partial segments less than 0.05 mile in length shall be combined with the immediately preceding full segment for profile index determination. Partial segments 0.05 mile in length or greater shall be analyzed separately. (3) Profile Index - The profile index is the inch per mile in excess of the 0.2 inch blanking band reported to the nearest whole number. The formula for converting counts to profile index is: Total Count x 0.10  Profile Index =
Length of Full 0.10 Mile Segment or of Partial * Mile Segment * Report to the nearest 0.01 mile. (e) Utility Appurtenances - If the Contractor is required to construct or adjust utility appurtenances, such as manhole covers and valve boxes, the tolerances stated in 00745.73(c-3) apply. 00745.75 Correction of Pavement Roughness - Replace this subsection with the following subsection: 00745.75 Correction of Pavement Roughness - Should testing described in 00745.73 show the pavement does not conform to the prescribed limits of deviation, the following shall apply: (a) General - The Contractor is responsible for locating areas that require corrective work. (b) Base Course - If the requirements of 00745.73(b) are not met, correct according to one of the following and retest. (1) Cold Plane Removal - Profile with equipment meeting the requirements of Section 00620.20 to a maximum depth of 0.4 inch. (2) Grinder - Profile with abrasive grinder(s), equipped with a cutting head comprised of multiple diamond blades to a maximum depth of 0.4 inch. (c) Wearing Course - After the Contractor has located and staked all individual deviations exceeding 0.03 foot, the Engineer and the Contractor shall meet at a mutually agreed upon time and drive the Project together. Each deviation will be evaluated during the drive-through to determine if corrective work will be required. Disagreements will be resolved by the Engineer. Correct all individual deviations identified for corrective work during the drive-through and any transverse joint that exceeds the requirements of 00745.73(c-3) by one of the methods listed below to the specified limits. (1) Remove and Replace - Remove and replace the wearing surface lift. Removal and replacement is required when the Profile Index is greater than or equal to 25 inches per mile. (2) Grind - Profile with abrasive grinder(s) equipped with a cutting head comprised of multiple diamond blades to a maximum depth of 0.3 inch and apply an emulsion fog seal as directed. Under the observation of the Engineer, retest each location requiring corrective work according to 00745.73 with a profiling device to verify that the deviation has been corrected to within the 0.03 foot tolerance. The Contractor may retest according to 00745.73 the entire length of all segments requiring corrective work, under the observation of the Engineer. Perform all corrective work and profiling at the Contractor's expense, including traffic control.
