3 ROUTE 80 West Bound From Route 46 to West of Parsippany Road Page 2 of 10 Norfolk Southern Corp. Preston Quade Engineer, Public Improvements Norfolk Southern Railway 99 Spring Street S.W. Atlanta, Georgia Tel: (404) , (404) pdquade@nscorp.com On page 50, subsection Surface Course Rideability Requirements is changed to: Surface Course Rideability Requirements. THE SUBSECTION HEADING AND ENTIRE SUBSECTION ARE CHANGED TO: Acceptance of Surface Course Rideability. 1. General Requirements. The HMA surface course placed in the traveled way will be evaluated in terms of the International Roughness Index (IRI) as defined in ASTM E 1926, Standard Practice for Computing International Roughness Index from Longitudinal Profile Measurements. Provided the requirements for localized roughness in Subpart 3(c) are met, ride quality acceptability will be judged in terms of percent defective (PD), defined as the percentage of work falling outside specification limits. The measured PD will be used to compute the appropriate pay adjustment, which may be positive for superior quality work, or negative for defective work. 2. Specific Requirements. For this project the PD will be calculated using an upper IRI limit of U = 70 inches/mile. (a) Acceptance will be based on lots of 0.1-mile length in a single lane. In certain cases, irregular lots of other than 0.1-mile length will be evaluated as described in Subpart 6(f). (b) To be judged acceptable, no more than PD = 10 percent of the work shall fall outside specification limits. (c) For PD values less than 10 percent, the work is eligible for some degree of bonus payment in excess of the contract price. (d) For PD values exceeding 10 percent, the work will be assessed an increasing amount of pay reduction (e) At extremely low levels of quality (PD 90), the NJDOT may require corrective action or removal and replacement at the Contractor s expense. If the NJDOT elects not to enforce this option, the pay adjustment will be computed as specified in Subpart 6. Corrective actions to improve defective work will not result in positive pay adjustments. 3. Smoothness Measurement. (a) Mainline Paving. The HMA surface course will be tested for ride quality with a Class 1 Inertial Profiling System as defined in AASHTO Designation MP 11, Standard Equipment Specification for

4 ROUTE 80 West Bound From Route 46 to West of Parsippany Road Page 3 of 10 Inertial Profiler, approved in accordance with NJDOT Test Method R-1, Calibration/Verification and Operational Procedures for NJDOT, Consultant-Owned, and Contractor-Owned Profilers. The full extent of the lot will be tested in the direction of travel. The transverse location of the test will be in the wheel paths of vehicular travel, and all designated travel lanes will be tested. The single IRI value reported for each 0.01-mile segment of pavement will be the average of three repeat runs for both the left and right wheel paths. (b) Other Areas. Instead of the above, a 10-foot straightedge shall be used for the following areas: transverse profile of the finished riding surface, shoulders, intermediate paving layers, fractional lots less than 0.03-mile in length, and any other areas designated by the Engineer. Any areas that have more than a 1/8-inch deviation between any two contact points of the straightedge shall be corrected by the Contractor in a manner approved by the Engineer. Following correction, the area will be retested to verify compliance. (c) Localized Roughness. If any individual 0.01-mile segment of pavement, measured as described in Subpart 3(a), exceeds an IRI value of 100 inches/mile the segment will be deemed an area of localized roughness and will require corrective action by the Contractor and as approved by the Engineer. If the corrective action is not successful or deemed unattainable, the Engineer will assess a $500 pay reduction per incident. Lots containing localized roughness are also subject to the pay adjustments determined in Subpart 6 except that only the greater pay reduction from either Subpart 3 (c) or 6 (f) will be applied. Corrective action locations will not receive bonus payments. 4. Control Testing. Control testing during placement shall be conducted as necessary to assure compliance with the specified surface requirement. An approved Walking Profiler, lightweight profiler, or high-speed profiler may be used for this purpose. 5. Preparation for Acceptance Testing. The Contractor shall provide the necessary traffic control when profiler devices are used and perform any required sweeping of the surface course prior to acceptance testing. Approved reflective traffic tape shall be placed transverse to the centerline across all travel lanes to be measured. The tape shall be placed 300 feet prior to the beginning and after the end of paving, bridge decks, and other locations as directed. 6. Lot Acceptance and Payment. For each 0.1-mile lot, there will be 10 individual IRI measurements as described in Subpart 3(a). For fractional lots, there will be fewer than 10 test results. At the discretion of the Engineer, testing of lots less than 0.03 mile in length may be waived or accomplished as described in Subpart 3(b). (a) Compute the sample mean ( X ) and standard deviation (S) of the N test results (X1, X2,, XN): X = (X1 + X XN) / N (Eq. 1) S = {[(X1 - X ) 2 + (X2 - X ) (XN - X ) 2 ] / (N - 1)} ½ (Eq. 2)

5 ROUTE 80 West Bound From Route 46 to West of Parsippany Road Page 4 of 10 (b) Compute the quality index (Q): Q = (U - X ) / S (Eq. 3) in which U is the upper limit defined in Subpart 2. (c) Determine percent defective (PD). Using Table for the appropriate sample size (N), determine the percentage (PD) of the lot that is outside the upper specification limit (U) specified in Subpart 2. (d) Retest provision. If the PD value determined in Step (c) above equals or exceeds the retest limit of PD Retest 50, the NJDOT has the option of performing a retest of the lot in question. If there is definite evidence that the initial test is invalid, the initial test will be disregarded, the retest will be performed, and will assume the status of an initial test. If there is no evidence that the original test was invalid, and the NJDOT elects to perform the retest, the PD values from the initial test and the retest will be averaged to determine the final result. (e) Rejection provision. If after an initial test, the PD value determined in Step (c) above equals or exceeds the rejectable quality level of PD Reject 90, the NJDOT will retest the lot. If there is definite evidence that the initial test is invalid, the retest assumes the status of an initial test, and an additional test will be performed before the lot is declared rejectable. If the final PD value equals or exceeds the reject value of PD Reject 90, the lot is declared rejectable and the NJDOT has the option to require removal and replacement at the Contractor s expense, or may allow the Contractor to submit a plan for corrective action. If the plan for corrective action is deemed unsatisfactory, the NJDOT may require removal and replacement, or may allow the lot to remain in place and receive the pay adjustment computed with Equation 6 in Step (f). If the plan for corrective action is accepted and the lot is reworked by the Contractor, it will be tested and evaluated as a new lot. (f) Compute pay adjustment. Pay equations 4-6 express the pay adjustment in dollars per lane per 0.1 mile. For lots of any other length, the pay adjustment is scaled up or down in proportion to the actual length of the lot. PD 10: PA = $ $100 x PD (Eq. 4) 10 < PD < 90: PA = $250 - $25 x PD (Eq. 5) PD 90: PA = $70,000 - $800 x PD (Eq. 6) SECTION 706 INTELLIGENT TRANSPORTATION SERVICES FACILITIES THE FOLLOWING IS ADDED:
