Thanks for all the replies. My driveway doesn't have too bad of a slope to it but it is enough to wash out little channel's in it when we get heavy rain, I did put some crushed concrete on it last year which helped but after all the traffic from my wifes daycare it is low where everybody drives and is evenstarting to washboard a little bit. I can get pretty much any of the stuff you guys have listed the only one I am not sure of is the limestone dust, crushed concrete is the easiest because there is a plant only 1/4mile from my house to get it from. As far as something to spread it with, I just put a down payment on a new kioti tractor but I am a total rookie with all of this stuff but my dad knows some about this stuff so he can help with the leveling and spreading of it. I really don't want to have to dig it out and redo a base but if that is what it takes to be more durable and require less maintenance that is what I will have to do.
