113.1Acceptance of Aggregate

1 The department will accept the gradation of crushed or screened aggregates used for pavements, bases, subbases, chip seals, and stockpiled materials with a gradation specification based on random samples taken at the direction of the engineer and a quality level analysis of the test results. Quality level analysis is a method of analyzing aggregate gradation test results to determine compliance with the contract requirements. The quality level analysis will include an evaluation for outlier test results usi ng the department’s computer software.

2 The engineer will determine the quality level, acceptance, and pay factor for each lot. Lot and sublot sizes are specified in the respective technical sections. The engineer will include partial lots with less than three samples with the previous lot for quality level analysis. All test results for a lot will be analyzed to determine the pay factor for the lot . The lowest pay factor computed for any one sieve will be used to adjust the pay for that lot. Acceptance procedures will not apply to sieve designations with requirements of 100 percent passing, 97 to 100 percent passing, and 95 to 100 percent passing. Only the P L (percent within lower limits) will be calculated for the sieve designations requiring 90 to 100 percent passing, and the PU (percent within upper limits) will be set at 100.

3 The maximum obtainable pay factor will be 1.05.

4 A lot containing material that does not meet the contract requirements will be:

5 To avoid a pay factor less than 1.00, the contractor may remove defective material and replace it with new material, which the department will sample, test, and evaluate in accordance with this specification.

6 Without testing, the engineer may isolate and reject material that is obviously defective. Do not continue producing material that does not meet contract requirements. If two consecutive lots have a pay factor less than 1.00, change procedures to meet the requirements.

Acceptance SECTION 113

7 The engineer will compute the quality level analysis and pay factor as follows:

Where: Σ= summation

x = individual test value

n = total number test values

𝑥𝑥̅ = Σ x 𝑛𝑛

𝑠𝑠 = ��

𝑛𝑛−1� ∑ (𝑥𝑥𝑖𝑖 − 𝑥𝑥̅)2𝑛𝑛 𝑖𝑖=1

QU = 𝑆𝑆𝐿𝐿𝑢𝑢− 𝑥𝑥̅ 𝑠𝑠

Where: SLU = upper specification limit or target value of job mix plus allowable deviation.

target value for QU = the single specification value with allowable deviations.

Q L = 𝑥𝑥̅−𝑆𝑆𝐿𝐿𝐿𝐿 𝑠𝑠

Where: SLL = lower specification limit or target minus allowable deviation.

given QU) from Table 113.1- 1, Quality Level Analysis by the Standard Deviation Method. If an SLU is not specified or if the upper specification limit for the sieve being evaluated is 100 percent, PU is 100.

QL) from Table 113.1-1, Quality Level Analysis by the Standard Deviation Method. If an SLL is not specified, PL will be100.

Acceptance SECTION 113

quality level = (PU + PL) - 100

Table 113.1-2, Pay Factors. To obtain a given pay factor, meet or exceed the value in the table for the computed quality level. Pay factors greater than 1.0 do not apply when quality incentives are not included in the respective technical specifications for a pay item.

8 Testing frequency indicates the minimum number of tests required for the specified quantity of aggregate produced. For example, 1/1000 ton [1/1000 t] is equivalent to one test minimum required for each 1000 ton [1000 t] of aggregate produced.

113.2Acceptance of Asphalt Materials

1 The engineer may conditionally accept cutback and emulsified asphalt materials at the source based on test reports for each tanker/pup delivered. Asphalt binder will be accepted in accordance with Subsection 401.2.1, Performance Graded Asphalt Binder.

2 Asphalt material used on the project that does not meet the contract requirements for the designated type and grade may at the direction of the engineer be:

by the nonspecification material at no additional cost to the department;

left in place with no payment made for the asphalt material used; or

Program’s current Schedule of Price Adjustments for Asphalt Materials in effect at the time of the award of the contract. The reduced unit price is based on the price

Acceptance SECTION 113

paid to the supplier or refinery for asphalt materials delivered to the project. Submit written documentation of these prices to the engineer. If prices are not submitted, the engineer will use unit bid price for asphalt materials.

113.3Unacceptable Work and Materials

1 The department considers the following unacceptable:

2 Work done contrary to the instruction of the engineer, work performed without subcontract approval, or any extra work done without authority will be considered as unacceptable. If the quality of the unauthorized work is acceptable to the engineer, the work may be left in place without payment.

3 The engineer will not allow continued production of out-of-specification material or work.

4 Remove rejected work and materials, including all portions of the work in which unacceptable materials have been incorporated, at no additional cost to the department. Rejected work and the traffic control to replace the work will not be paid for . The contractor may reuse removed material if it is adjusted to meet the contract requirements. If the contractor fails to remove, replace, or correct unacceptable work as requested, the engineer may direct other organizations to perform these activities and deduct the cost from monies due the contractor or bill the contractor, as appropriate.

5 The engineer may isolate and reject obviously defective material without regard to testing procedures.

113.4Final Acceptance

113.4.1 General

1 The department considers acceptance final and conclusive except as regards to latent defects, fraud, or gross negligence or with regard to the department’s rights under any warranty or guarantee.

Acceptance SECTION 113

113.4.2 Finish Conference

1 Either party may request a finish conference when the work has reached the point of substantial completion and the other party is notified in writing. The department requires the contractor’s project superintendent, at a minimum, to attend. The engineer and chief project inspector will attend for the department, along with others as necessary. Inspect the project together and discuss what still needs work before the contractor can request final acceptance. The engineer will provide a written punchlist of these items. The contractor may demobilize when the work required on the punchlist has been satisfactorily completed and approved by the engineer or as directed by the engineer.

113.4.3 Final Clean-up

1 Before requesting final inspection, clean the grounds within the construction limits. Remove rubbish, excess materials, temporary structures, and equipment, and leave the project in a condition acceptable to the engineer.

113.4.4 Final Inspection

1 Final acceptance of the project follows and is contingent on the results of a final inspection by the district engineer . Either party may initiate a final inspection. Provide the engineer with a written request for a final inspection. Make the request after satisfactory completion of the punchlist, in accordance with Subsection 113.4. 2, Finish Conference. The engineer will notify the contractor if the final inspection discloses incomplete or unsatisfactory work. Correct or complete the work immediately; the district engineer will then conduct another inspection. When the physical work is complete, the district engineer will give the contractor written notice of final acceptance as of the date of the inspection, and the department will assume responsibility for the project. The district engineer will send written notice of final acceptance to the contractor using USPS certified mail, “Return Receipt Requested.”

2 In writing, the contractor may request final acceptance of a portion of the work when that portion is complete and the use of that unit or portion is deemed necessary by the engineer for the convenience, safety, or both, of traffic . Final acceptance of a portion of the work does not amend the contract.
