QUALITY INDEX FOR PORTLAND CEMENT CONCRETE

CFS:CPM 1 of 9 APPR:JFS:TES:04-30-20

FHWA:APPR:05-19-20

a. Description. This special provision establishes pay factor and price adjustments for Portland cement concrete based on Department administered Quality Assurance (QA) testing of 28-day compressive strength and fresh concrete air content of Portland cement concrete (PCC).

Perform all work in accordance with the standard specifications and this special provision.

Percent-within-limits (PWL) analysis for payment adjustments apply for mainline, shoulder, miscellaneous concrete pavement (including ramps), and concrete pavement overlay applications. Non-PWL analysis for payment adjustments apply for all other applications.

b. Materials. Mixture requirements will be in accordance with section 1004 of the Standard Specifications for Construction, unless otherwise specified in the contract.

c. Sampling. Sampling will be in accordance with subsections 1003.03.H and 1003.03.L of the Standard Specifications for Construction, except as modified herein. A sample is defined as a representative quantity of concrete taken during production which is used to measure the quality characteristics for the concrete. Compressive strength specimens for each sample consist of two cylinders, either 4-inch by 8-inch or 6-inch by 12-inch.

1. PWL Applications. Production lots for PWL analysis are made of at least five approximately equal sublots. The Engineer may approve occasional small individual quantities of concrete to be combined with a larger production lot provided they are of the same grade, contain the same Job Mix Formula (JMF), and are used for the same PWL application.

The random number method for PWL sampling will be used to determine the sampling locations. A random number will be generated for each sublot. The sampling frequency for a production lot is one QA sample per sublot.

If a sublot is not completed in sufficient quantity to permit it to be randomly sampled during its production day, as planned, the quantity of concrete for the sublot that was not placed as part of the day’s production will be sampled during the following production day in accordance with the original random number sampling protocol. The random sample will then represent the total quantity of concrete for the sublot placed over the respective multiple days of production.

If the quantity of a grade of concrete to be sampled on the last day of production for the project is not sufficient to make up three or more equivalent sublots, combine the test results for these one or two remaining sublots, or fraction thereof, with the previous day’s production lot for quality index analysis.

The Engineer will mold and cure two additional compressive strength cylinders, in the same

CFS:CPM 2 of 9 04-30-20 manner as the QA specimens, that are to be retained in the event of dispute resolution.

2. Non-PWL Applications. See subsection 1003.03.L of the Standard Specifications for Construction.

3. Small Incidental Quantities. See subsection 1003.03.J in the Standard Specifications for Construction for reduced sampling and testing for small incidental quantities.

d. Quality Index Analysis. The Engineer’s QA test results will be used to determine the pay factor (PF) and price adjustment (ADJ). The Contractor QC test results will not be used for PF and ADJ analysis. The Engineer will complete PF and ADJ analysis within 7 working days after completion of all 28-day compressive strength testing for the represented production lot or quantity of concrete. All values for PWL, overall lot pay factor (OLPF), and PF are in percent.

PWL values are rounded to the nearest whole number. PF and OLPF values are rounded to two decimal places.

1. PWL Applications. The PWL, PF, OLPF, and associated ADJ will be determined using the MDOT Concrete PWL Worksheet. The acceptable quality level (AQL), rejectable quality limit (RQL), lower specification limit (LSL), and upper specification limit (USP) are shown in Table 1. The Engineer will perform the quality index analysis for all concrete represented by lot size and makeup necessary for random sampling.

A. Pay Factor Determination for PWL Applications. The MDOT Concrete PWL

Worksheet uses the following formulas to calculate the PF and associated ADJ for each production lot. The maximum calculated numerical values for PF and OLPF will not exceed 105.00.

(1) Pay Factor for 28-day Compressive Strength (PFs). If PWL for 28-day compressive strength (PWLs) is 95 to 100 inclusive, use the following formula to determine PFs:

PFs = 5 + PWLs

CFS:CPM 3 of 9 04-30-20

If PWLs is from 50 to less than 95, use the following formula to determine PFs:

PFs = 47.22 + (0.5556 x PWLs)

If PWLs is less than 50, the production lot is rejectable and the Engineer will require additional evaluation to decide what further action may be warranted as described in section e of this special provision.

(2) Pay Factor for Air Content of Fresh Concrete (PFac). If PWL for air content of fresh concrete (PWLac) is 70 to 100 inclusive, use the following formula to determine PFac:

PFac = 55 + (0.5 x PWLac)

If PWLac is from 50 to less than 70, use the following formula to determine PFac:

PFac = 37.5 + (0.75 x PWLac)

If PWLac is less than 50, the Engineer will elect to do one of the following:

(a) Require removal and replacement of the entire production lot with new testing conducted on the replacement concrete and repeat the evaluation procedure.

(b) Provided no individual test results for the production lot are outside the suspension limits for air content, allow the production lot to remain in place and apply an Overall Lot Pay Factor (OLPF) of 50.00.

(c) Allow submittal of a corrective action plan for the Engineer’s approval. If the Engineer does not approve the plan for corrective action, subsections d.1.A.(2).(a) or d.1.A.(2).(b) of this special provision will be applied, as determined by the Engineer. All costs associated with plan submittal and corrective action under this subsection will be borne by the Contractor. Positive ADJ (quality initiative) will not apply for production lots subject to corrective action.

(3) Overall Lot Pay Factor (OLPF). Use the following formula to calculate the

OLPF:

OLPF = (0.60 x PFs) + (0.40 x PFac)

B. Price Adjustment for PWL Applications. Both pay factors (PFs and PFac) must be

100.00 or greater for the production lot to be eligible for positive ADJ (quality initiative) consideration. Use the following formula to determine price adjustment for each production lot, using the established Base Price for the pay item included in the contract:

ADJ = (OLPF-100)(Price)/100

2 Non-PWL Applications. Positive ADJ (quality initiative) does not apply for non-PWL applications. Each individual QA strength sample test result will be used to determine the PF and ADJ for the respective quantity of concrete that it represents, based on the sampling rate.

The specification limits for non-PWL applications are defined in Tables 2 and 3. Unless otherwise specified in the contract, concrete not conforming to the requirements specified in Tables 2 and 3 is rejectable and subject to further evaluation.
