Hello all,
I am constructing a private asphalt road to serve a small residential neighborhood in Oklahoma. City requirements are forcing me to construct the road in such a manner that "it can withstand 70,000-75,000 pounds", which they claim is the weight of our fire trucks. From a practical standpoint, I will almost certainly never have a fire truck on the actual road (there will only be 6 houses), but we will have garbage trucks on it once a week, which are probably in a similar weight class.
I am trying to determine how thick my asphalt needs to be in order to be able to have a local structural engineer sign a letter certifying that my street design will suffice for that weight load. We are using 5% CKD from a pre-calciner plant for stabilization and our sub-base is a sandy/clay (mostly clay).
For cost purposes, I am hoping to get a certification for 4 inches, but could do 5 inches if necessary. Six inches gets way outside of our budget, so I'm hoping I can avoid that at all costs, no pun intended.
