I'm looking at replacing or repairing a 720 sq. ft. driveway and also front and back steps. I currently have concrete which is 51 yrs old and breaking up badly in some areas. Front and back steps have setteled 2-3 inches. I'm on sand..use to have a gravel/sand pit across the street. Am also dealing with the temp.changes(extremes) of Minnesota. Help! Also what's the difference between class 5 gravel vs. quarry rock for a base?
