Comment: Wrong reason ... (Score 1) 536

I am no fan of Perl, but if you have an application that is mission critical, has lots of legacy code, and just works, then you do not go about rewriting it just because there is some dislike for the language.

If it was something related, such as difficulty of finding suitable candidates for developer positions, then I would understand. But just because "perl is ossifying" does not cut it as a valid reason.

Actually, this is also incorrect. They do not decide what the law means, there is no decision involved. They attempt, to the most exactingly precise level possible, to determine what congress intended when the law was enacted. It is rare indeed that a law is so vague that it's intent cannot be determined with a reasonable amount of clarity.

Or, should I say, it used to be rare...

Glass (and obsidian for that matter) are crystalline in structure, making them hard and brittle. Exactly what you do not want in a road surface. Rock on the other hand is usually an amalgam of several materials, meaning that it can be scraped and chipped, but is less likely to develop cracks that propagate. Using regular ordinary gravel in asphalt also means that the rock pieces are not subject to localized large forces, as the exposed surfaces of the gravel stones flex away thanks to the bitumen. The twin properties of flexibility and a hard wearing surface are what make asphalt able to stand up to being hit with tonnes of force hundreds of thousands of times a year and still last decades between having to be relaid.

I agree that it's probably not the case that we can't do better, but the question is about current materials technology and economic viability. Could we do better if we spent $1m per square meter of road surface? Possibly, with those newly emerging exotic resins and fibers. Would a $1m/sqm price tag mean that the project has any chance of success? No.

When I said "solid bitumen", I was referring to traditional road materials, and not a bitumen only tarpit. Sorry for not being specific.

Also, "durable" is a relative term. We're talking about roads. Solar panels are durable when compared to, say, laptop screens. They are not durable in the context of road surfaces. Yes, there are amazing glass types around today, but once again, in the context of road surfaces, I don't think glass is, or could ever be, an appropriate material.

Bitumen+gravel is used because the stone gravel provides excellent wear resistance while the bitumen holds it in a flexible and self-healing suspension. It is still the best road surface material we have by a country mile.
