¹ Note: One sample for the first two hours of equipment operation; one immediately after, remaining samples at random over the rest of the day. Full production is considered when a Lot has more than eight hours of equipment operation.

² Note: Up to five per Lot if penetration results of the first sample is in price reduction/rejection range. Penetration testing of any Lot may be waived if the Consultant is confident that the recovered asphalt penetration requirements are being met.

³ Note: Frequency refers to Stratified Random Testing. Non-Random test frequency shall be 5 tests per Lot. (See Specification 3.50.4.4.2.4, Exclusions to Random Sampling)

⁴Note: Requires the determination of the mixture's Theoretical Maximum Specific Gravity for each mix sample.
