Hopefully I can answer all questions in one reply

. What's in the pics took three loads of a dual axle dump truck each load being 18 tons so total of 54 tons !

The price per load was 425.00 with the labor to put it down , level it and roll it of 1500.00 for a total installed price of 2775.00 . That gave me 700 ' of driveway averaging about 10.5 ' wide , one more load would have done the entire driveway . But the portion behind the house that isn't done is totally flat so not a problem .
I have been in Georgia for coming up on 9 years and never had a heavy freeze , in general the coldest it gets here is the low 30's . So I don't expect any heaving/shifting due to freezing . I have no clue how well this holds up to rain or anything else as I've only had it down for one day

But based on what some locals have told me , and the replies on this thread I think it will hold up well . I think that raps this up ....... go DAWGS !
