They're all over the map, so to speak.

You have to be kidding,

I was taking some college night courses and one of the projects we had to do was to manage a civil engineering project that included road building. A lot of us didn't have a civil background, but the information was out there.

Only thing is, one had to put forth a little effort.

Which is why I think the answer should be, "No". They will never know the strength of a road for several reasons; laziness, inability to comprehend and the uncertainty between plans and reality.

I agree,

I was fortunate that when I investigated it the only thing on the line was grades on our project. And I was thinking. I was initially taught investigative procedures consisted mainly of you library card and the ability to cross reference the Dewey Decimal system..

So, at my night classes, I didn't think it required much effort at all, and actually felt guilty. But that passed, and so did I.

But the OP laziness is no excuse

Without using either a search engine or a reference book of some sort, the only way of knowing is to carry out tests. CR4 is not a search engine, does not have any reference books, and does not offer a testing service.

Wrong country, CSIR is South Africa and this lad is in India. They build roads differently in S Africa. In the rest of Africa they build potholes with asphalt surrounding it.

Concrete, not in Africa, too expensive and they steal the concrete before you get to use it. That is why they have dirty roads, it is cheaper to build and 4x4's can negotiate these roads easily.

Asphalt flexes more but concrete lasts longer.

Absolutely, I see no reason why you cannot know this information.

I suggest you pay a visit to your local paving contractor. There you will find a complete list of paving specifications for any material or location. The specifications are likely jurisdictional sensitive.

Seriously? You need to crack open a few Civil Engineering books on the subject, starting with Soil Mechanics.

Download a few of the applicable USACE Engineering Manuals (see link below) and start reading and studying.

Failure is not an option.

Have you looked at the OP's profile?

- He lists as a home page an Engineering company.

- The Topics he has started tend to be either questions about basic Engineering, thinly disguised sales pitches for his company, or solicitations for Engineers to join his company.

I'm not going to give my opinion here, I'll just let you all look at the evidence and judge for yourself.
