all i know about road resurfacing is that it’s stimulus to unions and bullish for The Mob.
Our cabin is east of Duluth, in Wisconsin. We always "laugh" when we cross the state line and the roads improve 100%.
Is the road made of 100 percent recycled asphalt then ?
Cheap resurfacing is preferred by politicians because it needs to be redone frequently, necessitating frequent campaign contributions to win contracts. A quality road lasts, so contributions are less frequent. And what politician really knows how long he’ll be around?
Fascinating procedure and it really works!
Cheapie resurface to make the politicians good.
Kinda like wetting yourself wearing dark trousers. Gives you a nice warm feeling, but nobody seems to notice.
There’s nothing wrong with the old material but it sounds like they’re just doing a crappy job.
I live near Michigan International Speedway and when they resurface that, they mill the old surface and it goes into the surrounding roads.
BTW! Too frequently on FR, someone asks a legitimate question and all that result are irrelevant rants
You found "Hot inplace recycling." There's also a cold inplace recycling process. The difference is in whether the road surface is heated before it is ground off.
I've seen a lot of cold in place recycling here in the south (Florida and Georgia). The results depend on how deep they grind and the quality of the road bed below the road.
The process grinds off the surface of the road, reheats it, mixes it with some new binder material, then feeds that recycled asphalt into a paving machine to reapply it to the road.
This process will never fix underlying issues with the road bed. If you have frost heaves that go down to the road bed, the result will be a smooth wavy surface that follows the damaged roadbed.
Also, the deeper they grind, the better the resulting surface seems to be and the longer it will last. Depending on the machinery and how it is set, it's possible to grind as little as 2 inches off and recycle it, or as much as 6 to 8 inches. Deeper grinding usually results in a better quality result. How deep you can go depends on how thick the pavement is on the road. Obviously, you can't grind off 6" of pavement if that's all there is on the roadbed. Usually, it's not wise to grind more than half the pavement off for the process. If the pavement is only 8" thick, then 4" is about all that can be done.
Sorry, no personal knowledge of the repaving process.
I’ve been spending a lot of time in Rochester, NY as my sister is in hospice care in a home within the city. Last Wednesday, everyone had to have their cars off the street so they could resurface it. It sounds like it might be similar to what you have there. The surface is bumpy, and there are still a lot of loose stones after more than a week. When you drive down the streets that have undergone this process, clouds of dust fly everywhere. You have to watch your speed as it feels you are driving on a road of loose gravel, and your wheels slip if you try to accelerate. It’s horrible. I was told they’re using this technique to save money. They might be saving cash, but it’s ruining the finishes on people’s cars. Everyday when I leave the home, my car has a layer of dust all over it.
This sounds a lot like what they’ve done recently to Alabama Route 24 between Moulton and Russellville. And not for the better, I might add. The new surface is so noisy, I drive in the left lane for miles at a time.
