966 SECTION 720 SMOOTHNESS TESTING 720.1 -DESCRIPTION : To measure and evaluate the ride quality of pavement surfaces in accordance with the International Roughness Index (IRI), as well as the most recent forms of AASHTO R -56, AASHTO M328, and AASHTO R -57. 720.2 -EQUIPMENT : 720.2.1 -High -Speed or Low Speed Inertial Profiler: Provide a high -speed or low speed inertial profiler for measuring and evaluating the ride quality of pavement surfaces. The inertial profiler shall be certified at a facility approved by the Materials Control, Soils and Testing Division (MCS&T). Certification facilities should conduct the evaluation in accordance with the most recent edition of AASHTO R -56 “Standard Practice for Certification of Inertial Profiling Systems”. All inertial profilers shall be maintained in accordanc e with the most recent edition of AASHTO M 328 “Standard Specifications for Inertial Profiler” Calibration and verification shall be done in accordance with MP 720.10.0. The Contractor shall submit equipment certification documentation after becoming certified or after recertification. Proof of eq uipment certification shall be available upon request. 720.2.2 -Inertial Profiler Operator Certification: Certification through the Material Control, Soils and Testing Division shall be required to operate an inertial profiler in the State of West Virginia. The operator shall pass a written exam administered by MCS&T. All operators receiving a passing score o n the written exam will be placed on the WVDOH Materials Certification Directory that is found on the MCS&T webpage. Certification shall be for a period of three years. Certified operators shall contact MCS&T for certification renewal. 720.3 -RIDE QU ALITY TESTING 720.3.1 -Quality Control (QC) Testing: QC testing on NHS routes is the responsibility of the Contractor. QC testing shall be completed in accordance with MP 720.10.01 Section 8 no later than fourteen (14) calendar days after all lanes are continuously open to traffic. Data collection shall be done by a certified inertial profiler and certified inertial profiler operator (See 720.2.1 and 720.2.2,). Collected profile data shall be submitt ed to the project engineer in accordance with MP 720.10.01 Section 10 within five (5) calendar days of testing. 720.3.2 -Quality Assurance (QA) Testing: QA testing is the responsibility of the Division. The Engineer shall submit a “Bridge and Pavemen t Testing Request Form” form to MCS&T via email, within five (5) calendar days after all lanes are continuously open to traffic. Within fourteen (14) calendar days from receiving the request, the Division will conduct QA testing. The Division will use a certified inertial profiler and certified operator for QA testing. 720.3.3 -Quality Assurance Verification (QAV) Testing: QAV testing is the responsibility of the Division. The Division’s profile data and the Contractor’s profile data will be compared to determine the IRI differences. Final project price adjustments will be made using the Contractor’s profile data if the IRI differences are within the allowable limits outlined in Table 720.3.3. 967 TABLE 720.3.3 QAV Testing Allowable IRI Differences Contractor’s IRI Mean (in/mi) Maximum Allowable Differences 50.0 or Less 8.5% of Contractor’s IRI Mean 50.1 to 150.0 6.0% of Contractor’s IRI Mean 150.1 or Greater 7.0% of Contractor’s IRI Mean 720.3.4 -Referee Testing: Referee testing is the responsibility of the Division. If the QAV testing IRI differences does not meet the maximum allowable difference from Table 720.4.3, the Division will perform referee testing using a certified inertial pro filer and a certified inertial profiler operator in accordance with the most recent edition of AASHTO R 56 “Standard Practice for Certification of Inertial Profiling Systems”. The profile data from the referee test shall be used in determining the final p roject price adjustments. 720.3.4.1 -Referee Data: If the referee test data still does not meet the allowable IRI differences MCS&T can recommend the Contractor recertify their inertial profiler and inertial profiler operator that was used on the project. 720.3.5 -Testing After Repairs: Should repairs be needed to the surface from the defects in the pavement prior to project closeout, QA and QAV testing shall be conducted after all repairs are made. This will be the final tested value for the lo t. 720.4 -RIDE QUALITY ANALYSIS : 720.4.1 -Data Location: The average IRI number used in ride quality analysis shall be the mean roughness index (MRI) which is the average IRI of both the left and ri ght wheel path. Analysis shall be done in accordance with MP 720.10.01 Section 9. 720.4.2 -Omitted Sections: Bridge Structures and any sections tested which are not included in the pavement project shall be removed from the Smoothness Analysis. These r emoved bridges and sections shall also include a Lead -In and Lead -Out distance to be removed from the Ride Quality Analysis. The Lead -In distance shall be two hundred (200) feet and the Lead -Out distance shall be two hundred (200) feet. 720.4.3 -Samplin g Lots: The pavement shall be divided into sampling lots of one -tenth (0.1) lane mile each. Each Lot shall have a smoothness measurement, expressed in inches per mile (in./mi.). 720.4.3.1 -Special Cases for Sampling Lots Less Than One -Tenth (0.1) Lane Mile: In some cases, sampling, lots of one tenth (0.1) lane mile will not be attainable. These cases include areas at the end of the project as well as areas that are before the ‘lea d in” length of bridges. If these areas are less than five -hundredths (0.05) of a lane mile that will be eliminated from Smoothness analysis. If these areas are more than five -hundredths (0.05 mile) lane mile these areas will be included in analysis and pa y adjustments will be prorated to the nearest one hundredth (0.01) mile. This shall apply to all projects governed by Section 720. 968 720.5 -NATIONAL HIGHWAY SYSTEM (NHS) PAVEMENT PROJECT : Pavement projects located on any NHS route and greater than 0.2 miles of continuous new pavement shall be tested with a high -speed or low speed inertial profiler certified in accordance with Section 720.2. 720.5.1 -Determining National High way System Routes : The NHS map should be used when determining if a route is on the National Highways System. This tool can be found online at the following link: https://wvdot.maps.arcgis.com/apps/dashboards/88e87932344946408b7c17f1bd454752 720.5.2 -Schedule 1 NHS Pavement Projects: NHS pavement projects with a pavement thickness of four (4) inches or greater shall be classified as Schedule 1 NHS Pavement Projects. The final price adjustments for Schedule 1 NHS Pavement Projects shall be determined using the calculations shown in Table 7 20.5.2.

1.Resurfacing is the primary project type
2.Greater than 1 mile of continuous pavement,
3.Edge lines and center line on the new pavement in accordance with Section 663.
4.Thickness of one inch (1) or more of new pavement (including scratch if used) 720.6.1 -Ride Quality Analysis Before Project: Non-NHS pavement projects shall be tested before the pavement project begins. Any new construction of a Non -NHS route will be evaluated as an NHS route according to 720.5. 720.6.2 -Data Source Collection After Project Completion: The data source collection after project completion shall be collected by the Division’s high -speed or low speed inertial profiler as referenced in 720.3.2. On non -NHS routes Quality C ontrol Testing is optional for the contractor. 720.6.3 -Final Price Adjustments: If the average precent improvement for the entire project is 30.1% or more, no price adjustment will be assessed for the project. If the average percent improvement for the entire project is 30.0% or less, then each 0.1 mile lot that has an IRI of 80.1 or greater, will be penalized based on the following table. Table 720.6.3. TABLE 720.6.3 Non-NHS Pavement Projects IRI for each 0.1 -mile section (in/mi) Price Adjustment ($ per 0.1 -mile Section) 80.1 – 170.0 320 - 4(IRI) 170.1 or Greater -360 Where: Percent Improvment (%)= Before IRI of Lot −After IRI of same Lot Before IRI of Lot X 100 720.7 - PROJECTS THAT DO NOT FALL UNDER PREVIOUS CHARACTERIZATIONS : At the discretion of the Engineer pavement projects not falling into any of the other classifications shall be measured and evaluated for ride quality analysis under the direction of the Engineer. If recommended by the Engineer this shall be done by the C ontractor with a ten (10) foot straightedge. There will not be any pay adjustments based on Smoothness for these projects.
