Application of Price Adjustment

 

1.     For Structural Concrete, when a lot verification sample is non-complying, the limits of the non-complying material will be determined by testing previous and subsequent lot verification samples.

2.     For non-QM-C Paving and the #200 sieve for QM-C paving, when the lot verification sample is non-complying, the limits of the non-complying material will be identified by testing previous and subsequent samples within the lot.

3.     All percent passing (and average percent passing) values are to be calculated to two significant figures.

4.     The Price Adjustment percentage (to be applied to the quantity of non-complying material) is the sum of percentages determined for individual out-of-tolerance sieve sizes.
