718.20 Fine Aggregate :
Fine aggregate used to level the bedding material shall consist of crushed or uncrushed mineral aggregate which has no particles larger than 3/8 in ch (9.5 mm) as determined by visual inspection. The project Engineer/Supervisor may obtain samples on questionable materials for testing prior to use.
718.21 Bedding Material :
Bedding Material shall conform to 703 and meet gradation for #67. SECTION 719-BLANK 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.
