Refer to the Aggregate Gradation Tables in the Appendix.
A. Article 1106.04 applies. Stockpiles contaminated with organic or other foreign materials may be cause for rejection of the aggregate. The Engineer will determine acceptability by visual examination or other methods.
B. The Engineer may reject the use of material from ledges or beds that individually do not pass the quality requirements for the intended aggregate product. Specific production methods may be required to permit the use of material from marginal ledges or beds.
A. For PCC aggregate, driving on stockpiles is not considered an acceptable production or handling practice and may be grounds for rejection of the stockpile.
B. For all other aggregate stockpiles, if a ramp (incline or decline) is used to build the stockpile the ramp cannot be used as certified material. Incorporation of a ramp into a stockpile may be grounds for rejection of the stockpile.
For purposes of determining conformance with aggregate specifications, all specified limits are absolute limits, as defined in ASTM Practice E 29, for Using Significant Digits in Test Data to Determine Conformance with Specifications.
