Re: What kind of gravel for driveway?
I think you need to look at your application and what material is available. Here in NW PA we have all types of material depending on your budget. When we are looking to infill low spots with cheap material we use a 2A gravel or RC. This is sandstone material with fines which will compact. I just used 450 tons on a site, delivered was $ 9.45 per ton. I also used 2A limestone on this project and it cost $ 12.75 per ton a big difference. Around here if you just order gravel you get sandstone. You must specify limestone if you want it. Limestone is better and you want the fines so it will compact better. I just finished my driveway and I used #4 limestone in areas that I removed because of pumping and I laid 6" of 2A limestone over the entire length. Drive on it and a couple rains and it is like concrete with out the cement. Good Luck!
