Effective with the December 2018 Letting 533 2019 Standard Spec ifications Section 716 QMP Ancillary Concrete
716.1 Description
1.This section describes contractor mix selection and testing re quirements for class II and class III concrete.
716.1.1 Quality Control Program
716.1.1 1 General
1.Conform to the general requirements under 701 and 710 as modified here in 716 for class II and class III concrete defined as follows: - Class II: ancillary concrete th e department accepts based on field testing during placement. - Class III: ancillary concrete th e department accepts by certi fication.
716.1.1 2 Quality Control Plan
1.The contractor need only submi t an abbreviated quality control plan as defined in 701.1.2.3 .
716.2 Materials 716.2.1 Class II Concrete
1.Determine mixes for class II conc rete used under the contract according to 501. If a grade A mix is allowed under standard spec 501.3.1.3 , the contractor may use a cla ss I mix design approved under
715.2 Ancillary concrete placed integrally with mainline pavement is accepted using tests of class I
concrete but not eligible for incentive payment under 715.5 . Document the locations and quantities of integral concrete and identify the class I sublot tests used fo r acceptance. Revise 716.2.1(2) to require air and slump testing every 100 CY and cylinders every 200 CY for base patching.
2.Perform random QC testing a t the following frequencies: 1. Test air content and slump a minimum of once per 100 cubic yards for each mix gr ade and placement method. 2. Cast one set of 2 cylinders per 200 cubic yards for each mi x grade and placem ent method. Cast a minimum of one set of 2 cylinders per contract for each mix gra de and placement method. Random 28-day compressive strength cylinders ar e not required for HES or SHES concrete. 3. For deck overlays, perform te sts and cast cylinders once pe r 50 cubic yards of grade E concrete placed. 4. For concrete base, one set of tests and one set of cylinder s per 250 cubic yards.
3.Conform to the initial curing requirements under 710.5.5 except the contractor may extend initial curing for 72 hours before transporting the cylinders to a department- qualified laboratory.
4.Test aggregate gradations, including P200, as specified in 710.5.6 at the frequency listed below which results in the least number of tests: - A maximum of one test per day. - A minimum of one test per 400 c ubic yards of cumulative concrete placed. Alternatively the engineer may ac cept aggregate based on docume nted previous testing.
5.Department verification testing is optional for aggregate used in class II concrete.
716.2.2 Class III Concrete
1.Acceptance of class III concrete i s based on a certificate of compliance. Submit the certificate of compliance at least 3 business days before producing concrete a long with the initial concrete mix documentation as required under 710.4(2) .
2.Contractor testing for the mix and mix aggregates is not requi red for the items contained within the certificate of compliance. Conform to 716.2.1 for items not contained within the certificate of compliance.
3.Department verification testing is optional for class III conc rete. Correct any deficiencies found during the QV testing.

Effective with the December 2018 Letting 534 2019 Standard Spec ifications Section 730 QMP Base Aggregate Add section 730 to incorporate STSP 301-010 QMP Base Aggregate.
730.1 Description
730.1.1 General
1.This section describes contractor QC and department QV testing and documentation for base aggregates. Apply to Base Aggregate Open Graded bid items and t o Base Aggregate D ense bid items except reclaimed asphaltic pavem ent placed under the Base Aggre gate Dense bid items.
2.Do not apply to Aggregate Detour s, Breaker Run, Select Crushed , Pit Run, Subbase, or Riprap bid items.
3.Conform to the general QMP requirements under 701, to the base aggregate requirements under 301, 305, and 310, and to the additional requirements specified here in 730.
730.1.2 Quality Control Program
730.1.2 1 Quality Control Plan
1.Submit a plan conforming to 701.1.2.2 and include additional information as follows: 1. Section and quarter descripti ons for all aggregates that re quire QC testing. 2. Description of stockpiling and hauling methods.
730.1.2 2 Small Quantities
1.The department defines a small quantity of base aggregate as a contract quantity of 6000 tons or less placed under a single bid item.
730.1.2 3 Documentation
1.Submit test results for gradation, fracture, liquid limit, and plasticity to the engineer within 1 business day of obtaining the sample.
2.Maintain standardized control charts according to CMM 8-30 .
3.Maintain separate gradation cont rol charts for each sieve size specified in 305 or 310 for each base aggregate size, source or classifi cation, and type. Set the con trol limits and warning limits as follows: 1. The control limits are the upper and lower gr adation specif ication limits. 2. Warning limits: - There are no upper warning limits for sieves requiring or all owing 100 percent passing. - There are no lower warning limits for sieves allowing 0 percent passing. - Dense-graded No. 200 sieve: warning limits are 0.5 percent wi thin the upper and lower control limits. - Dense-graded for all other sie ves: warning limits are 2 perce nt within the upper and lower control limits. - Open-graded 1-inch, 3/8-inch, and No. 4 sieves: warning limit s are 2 percent wit hin the upper and lower control limits. - Open-graded No. 10, No. 40, and No. 200 sieves: warning limit s are 1 percent wit hin the upper and lower control limits.
4.Maintain a separate fracture c ontrol chart for each base aggre gate size, source or classification, and type. Set the lower control li mit to the value specified in table 301-2 . Set the lower warning limit 2 percent above the lower control limit. There is no upper warnin g limit.
5.Plot QC and QV test results and the 4-point running average on control charts. Include only QC placement tests in the running average unless a QV test result is out of spec, then include it as specified in 730.3.5(5) . Document corrective action on control charts. Update control charts and submit copies to the engineer daily.
730.2 Materials
1.Provide materials conforming to 301, 305 , and 310.
2.Use the definitions in 301.2.2 and the following: Stockpile Sampling Coordinated QC/QV sample before beginning placement of aggregate materials.
