Actually for what we're designing, it IS that simple. This is just a private driveway for a single-family residence. The Los Angeles County Fire Department is requiring the driveway meet H20 loading so that it will be able to handle their fire trucks --but the frequency may be only once for that...
Ah yes, I had a feeling I was just making a bad comparison. Thanks so much Ron for bearing with me on this! The more I think about it, the more it looks to me like I'm using the wrong documentation (accelerated wear testing) to prove my material selection. I've already asked the manufacturer to...
Well, from what I've researched, your statement of what H20 loading is seems incorrect. It is NOT a single 24,000 lb rear axle or two 16,000 lb axles but just a SINGLE 32,000 lb single axle load. There's even an HS20 spec that adds the second rear axle --but BOTH of them are still at 32,000 lbs...
Hmm, from what I found, it looks like the maximum axle loading of the H20 spec is 32,000 lbs. Here's where I got that from:

My problem is that, after further reading, the engineering white papers from the pavement we're wanting to use had 18,000...
I have a pavement manufacturer that has performed an accelerated wear test on a product we'd like to use in Los Angeles County but our Fire Department is requiring us to use only pavement products that are capable of H20 loading. The problem is that the engineering documentation from the...
