Sparkplug, no I used the term "up to 5 inch"...they used the term "5 inches and smaller"...there are many aggregate sizes; > 1", 1 to 2", 2 to 3", 3 to 5" and larger.
While I've never bought stone in Texas, I will admit to being baffled by this particular grading system. Here, stone is bought by the grade, or number. The larger the number, the smaller the stone GENERALLY.
For a new driveway, I like #2 for a base (average around 3-4" or so), and then top dress it with #8 (3/4-1"). #11 is about the size of a fingernail.
