Round here we call it 'lime waste' or 'the fines' meaning the particles of limestone, just above agricultural lime. If being placed on soil I would suggest 'base rock' it has from 3/4 inch to fines mixed with water content, this is intended to be compacted while moist as a base layer for Asphalt. Get it dry though. add your own water after placing it in 3 inch lifts, sets up like concrete if you do it right. contact a local asphalt Co. or rock quarry. Not sure what you would have available in TX. Warning; This hard and heavy work, and not easy remove.
For a small area around my 'back yard bees' I pin down black landscape fabric right on top of the ground. I buy the 3 foot wide stuff you can get anywhere, I lap it under my hive stands (concrete blocks in my case) so it's almost 6 feet of coverage, the weight holds the lapped portion down. Pin the edges with #16 or #20 galvanized nails. this allows me to mow right over this edge and no weed eating needed. Just an idea.
