MnDOT standard beam box <br />size is 6" x 6" x 20" unless other sizes or types are approved by the <br />Concrete Engineer. <br />Determine texture testing locations using random numbers. <br />Determine probing and coring locations using random numbers. Initial <br />pavement at core locations and re -initial the sides of specimens after <br />coring to clearly verify their authenticity. <br />None <br />2448 <br />Weekly <br />Concrete <br />Report <br />2162 Test <br />Beam Data <br />Probing, <br />Coring, <br />Texture <br />and MIT - <br />Scan T2 <br />Report <br />Concrete <br />Profile <br />Summary <br />Work <br />Sheet <br />Contact the MnDOT District IA Inspector to provide servicing of your Federal Aid Project. <br />NOTE (1): All gradation samples shall be taken in the presence of the Agency, unless otherwise authorized by <br />the Engineer. All samples shall be taken off the belt leading to the weigh hopper unless otherwise approved by <br />the Engineer. All gradations and quality tests require companion samples. If Coarse Aggregate Quality <br />Incentive / Disincentives apply: The Agency may also use the QA samples for incentive / disincentive testing. <br />Notify the producer to double the QC/QA sample size. If well -graded aggregate incentives apply: Use the <br />Contractor's gradation results for well -graded aggregate incentive calculations as verified by Agency testing. <br />Use the Well -graded Concrete Agg Worksheet. <br />NOTE (2): If w/c incentives apply: Use aggregate moisture results for determining the water content to <br />calculate the w/c incentive / disincentive. Use the Concrete W/C Ratio Calculation Worksheet and do not leave <br />sample unattended. <br />NOTE(3): If w/c incentives apply: Microwave oven verification testing to verify the w/c ratios is completed in <br />conjunction with Agency aggregate moisture testing. Do not leave samples unattended. <br />NOTE (4): Prior to concrete production: Obtain pre -production samples for quality testing at least 16 hours prior <br />to concrete production. Samples may be taken from the stockpile and -200 test may be performed at the lab <br />instead at the plant at the discretion of the Engineer. If the entire project is <3,500 yd3, pre -production <br />sampling is not required. <br />Minimum Aggregate Sample Size *companion required, double sample size <br />Aggregate Size Gradation* Quality* Moisture % -200 C.Agg <br />3/4" Plus, #4 25 Ib. 50 Ib. 2000 g 10 Ib. <br />3/4" Minus, #67 25 Ib. 30 Ib. 2000 g 6 Ib. <br />#7, CA-70 6 Ib. 30 Ib. 2000 g 6 Ib. <br />CA-80, #89 1.1 Ib.
