CEM-3502 (REV 11/2009)
Random Sampling Instructions
For method and standard process projects, the specified lot size is the total quantity of hot mix asphalt to be placed for the project.
A lot is defined by a single accepted JMF. For QCQA, the lot must be terminated if the JMF is changed, if 20 sublots are
completed, or if production quality factors do not meet standards specified in the contract.
Specified lot size = 5,250 tons (per engineer's estimate)
Hot mix asphalt samples are required at a frequency of 1 for every 750 tons.
1. Using the random number table, randomly select a block of numbers (Note: ASTM D 3665 provides random number
tables).
2. Multiply the random number by the sublot quantity.
3. Add this value to the sublot factor to determine the first sampling milestone (tons of production at which a sample will be
taken).
4. Continue this process for additional samples as required. Return to step 1 if lot is terminated and a new lot is begun.
