General Comments for this Test: Sample took place after both truck sat for a few minutes while previous load finished discharge, and then discharge of half of the load. Caltrans QA was okay with air result provided subsequent testing was within range. Immediate testing of next truck was not possible owing to finishing sample testing and cleanup. Loads 7 and 8 were tested, 7 was rejected for air and slump, 8 was acceptable.
