When the average daily spread rate is outside this tolerance from the target, adjust the <br />spread rate to the required value established by the Engineer. The Engineer will periodically <br />verify the spread rate at the job site during the paving operation. <br />234 -8.3 Allowable Deficiencies: The Engineer will allow a maximum deficiency from <br />the specified spread rate for the total thickness as follows: <br />1 . For pavement of a specified thickness of 2 1/2 inches [60 mm] or more: <br />50 Ibs /sy. <br />2. For pavement of a specified thickness of less than 2 1/2 inches [60 mm]: <br />25 Ibs /sy. <br />234 -8.4 Pavement Exceeding Allowable Deficiency in Spread Rate: Where the <br />deficiency in spread rate for the total thickness is: (1) in excess of 50 Ibs /sy for pavements <br />with a specified thickness of 2 1/2 inches [60 mm] or more, or (2) in excess of 25 Ibs /sy <br />�i for pavements with a specified thickness of less than 2 1/2 inches [60 mm], the Engineer <br />may require removal and replacement at no cost or may require a correction as specified in <br />234 -8.5. The Engineer may require the Contractor to core the pavement for thickness in <br />order to determine the area of pavement with deficient thickness. <br />As an exception to the above, the Contractor may leave pavement outside <br />the main roadway in place without compensation when the Engineer allows, even though <br />the deficiency exceeds the tolerance as specified above. <br />The Department will not compensate the Contractor for any pavement <br />removed or for the work of removing such pavement. <br />234 -8.5 Correcting Deficiency by Adding New Surface Material: In the event the <br />total thickness as determined by the spread rate is excessively deficient as defined above <br />and if approved by the Engineer for each particular location, correct the deficient thickness <br />by adding new surface material, and compacting it to the same density as the adjacent <br />surface. The Engineer will determine the area to be corrected and the thickness of new <br />material added. Perform all overlaying and compacting at no expense to the Department. <br />Elul 234 -9 Method of Measurement. <br />The quantity to be paid for will be the plan quantity. The pay area will be adjusted <br />based upon the following formula: <br />Pay Area = Surface Area (Project Average Spread Rate /Specified Spread <br />rate for the Total Thickness). <br />Where: The project average spread rate is calculated by totaling the <br />arithmetic mean of the average daily spread rate values for each layer, and the specified <br />spread rate for the total thickness is based upon the plan thickness converted to spread <br />rate as defined in 234-8.1. <br />The pay area shall not exceed 105% of the designed surface area. <br />Prepare a Certification of Quantities, using the Department's current approved form, <br />for the certified Superpave asphalt base pay item. Submit this certification to the Engineer <br />�I no later than Twelve O'clock noon Monday after the estimate cut -off or as directed by the <br />Engineer, based on the quantity of asphalt produced and accepted on the Contract. The <br />J certification must include the Contract Number, FPID Number, Certification Number, <br />Certification Date, period represented by Certification, and the tons [metric tons] produced <br />for each asphalt pay item. <br />0 <br />fa IX <br />March 2007 01000 -46 03- 4122.D a` <br />
