[QUOTE=Scot;48203048]you people ask to many questions[/QUOTE] When new or dumb ideas come around its good to ask questions.
[QUOTE=Trekintosh;48207921]What are the traction properties of the plastic? Don't want cars to just go flying off into a ditch every corner.[/QUOTE] yeah i think they're gonna make them really glossy and shiny just to fuck shit up
This sounds terrifying for anyone that rides.
[QUOTE=rampageturke 2;48211166]No I mean they end up cracked as shit when you get a freeze[/QUOTE] Okay, did you not read the part where I described the hellish conditions for civil engineers. or are you under the impression that the Upper Midwestern part of the United States is tropical? Plus I don't know what the hell you're on about with it being wet in the first place, more cracks would mean you get more traction and thus rain would not be a concern. [editline]15th July 2015[/editline] Seriously, it freezes here. A lot. I said -40C to 40C for a reason, that's the temperature differential from winter to summer, and we still have concrete roads.
[QUOTE=rampageturke 2;48211166]No I mean they end up cracked as shit when you get a freeze[/QUOTE] My garage floor doesn't explode on me when it freezes. Freezing isnt a death sentence for concrete or it wouldn't be used for anything.
[QUOTE=Cmx;48215190]My garage floor doesn't explode on me when it freezes.

Freezing literally breaks mountains, of course it's going to affect asphalt out in the wild as well.

What causes problems is that old concrete roads and highways have had about a decade of freeze/thaw cycles, intense compression 24/7 from the traffic, and additionally vibration from traffic that literally rattles the concrete apart.
[QUOTE=JumpinJackFlash;48204554]We have concrete bedded highways and roads in Minnesota, with a layer of asphalt on top. Our climate has a wildly vast temperature difference between summer and winter, basically you can't get more long-term demanding conditions than this region. (not just Minnesota, the surrounding states and Canadian provinces too) Anything engineered to work here has to survive -40C winter, 40C summer, and the transition between the two twice a year. We use concrete because it's very durable and lasts a very long time, and the noise factor isn't a big deal since road repair happens statewide as long as it's warm enough to pour the new asphalt or concrete. Even on all-concrete roads we really couldn't give a fuck about the noise, the road is arranged in slabs so going over them is a uniform and even sound that you stop noticing unless it's in need of repair. [/QUOTE] Just further info on this- If MN had the funds to get all their freeways converted to concrete, the state would save money in the long run. Concrete is low maintenance, easy to clean, easy heat, but extremely expensive. Theres a [URL="http://www.dot.state.mn.us/mnroad/"]stretch of highway, and an agency[/URL], dedicated to road research. Its the largest of its type in the world because of the weather. They actually just released a report in May regarding their findings.

I also got a boner at that moment, (shit happens) so I was concerned that the extraterrestrial employees of MnDOT were observing my erection. I honestly wish local communities would finally pony up the goddamn cash for the better highways. There was a vote in the LF area a couple of years ago about raising funds for it but it didn't pass because muh taxes!!! and I was disappointed. So we got normal asphalt on 10 where it meets 371, all the way up to Motley. Highway 10 between Staples and Motley is concrete though, and it was put in about a decade ago and it's still going strong. Don't get me wrong though, I love the feeling of driving over fresh asphalt. It's magic.
