May be a good idea to let them know that you mow with a cylinder mower and that the ' fine road base full of 3/16 gravel' will cause damage to your machine.They may just replace with soil, and all will be well. Also maybe the promise of a couple of 'coldies' at the end of the work sometimes works wonders...... Best of luck with it...
