Need a guideline for when to repave
(OP)
Have a potential client who wants to set up routine inspections of, among other things, their roads. This is a HOA responsible for long term maintenance, that needs to juggle their meager budget year by year to manage maintenance costs.
Ideally, I'm looking for a publication, or even just a website, that has rule-of-thumb photographs showing when it's necessary to top dress, repave, etc etc, that I can then tie in to estimates and whatnot to get an idea how they can best spend their money.
I did some asphalt mix design tech work for a road paving outfit in my college days, but that's the extent of my exposure with asphalt. No field experience.

With this process, you can develop a rudimentary pavement management system for your client. While the process is used for high level pavement management systems, it is also applicable to small pavement sections as well.
You can then do a PCI of the pavement, prioritize the repairs or replacement based on the condition, and better utilize the funds available for pavement repairs.
One thing you'll learn in the prioritization is that you only repair those sections that are amenable to repair, so that you can salvage them. Those that have very low PCI ratings may be allowed to deteriorate further so that full-depth reconstruction can be done at some point. For those pavement sections, "top down" repairs waste money.
Check with various state departments of transportation. Some of them have good, simple pavement management systems that can be adapted to local, small applications.
The Georgia DOT has a pavement condition rating system called PACES, but you'll have to call their maintenance office to get a copy of the manual...it does not appear to be available online.

"PACES"
**Perfect**
Thanks.

..which is very interesting. Covers some of the basics, and it's free.

The GDOT manual is similar to other states, all based on the AASHTO method, which is fine.

Thanks again for pointing me in the right direction. Definitely earning your pink stars, sir.

We have set up a reserve fund to mill and overlay approximately every 25 years. The original pavement lasted about 20 - 22 years and then was re-done. It has lasted 10 years now and still looks relatively good.
Since this is just a local, private street, the only real load the pavement sees is the weekly garbage truck and the occasional fire truck or moving van.
Every time you seal coat, walk the job with the contractor and you can get an evaluation of the general condition.

Worked as a co-op with APAC Material Services Division, under Dr. Randy West, back in APAC's hey day. (I think Randy is back at Auburn now, at NCAT) Back in the 90s, APAC was set up as a family of semi-independent paving companies all owned by Ashland Oil, with a side company ("APAC Inc.") that functioned merely as a services company for the other companies in the organization. It was a very lateral corporate hierarchy, and very lean, and competitive. APAC Mat Svcs was a lab that did all the difficult mix designs that individual divisions didn't have the expertise to do themselves, and also did a lot of private research and training, particularly when DOTs were moving away from Marshall design. Fun co-op job for a couple years, but half of what I did was just shake rock and pound pills. :)

I realize they don't need a science project, and I believe the guy I was approached by realizes this as well, but the rest of the home owners are pointing at some hairline cracks and doing the Handwaving Freakoutery routine, so I think he wants something written up that settles them down. Thanks a bunch for the timelines you posted. That will help a lot.

You could learn quite a bit and perhaps do a little marketing at the same time by calling the City engineer or at least the engineer in charge of the city streets. Find out what their maintenance schedule is and maybe they can also give you some guidelines. Your nervous nellie homeowners might be re-assured by that information.

I would warn against using a spray-applied or even a squeegee applied coal tar emulsion as a surface treatment. In my opinion those are a waste of money.
If you go with a surface treatment, make it a slurry seal or "microsurfacing" approach using asphaltic materials, not coal tar.

Ron, who'd you work for in Atlanta?

~500 people sounds like JJ&G, depending on the timeframe.

Yep...Law has a big alumni association! Great training ground in engineering, though!
