I'm very much into wood working which involves some hand tool sharpening. In the sharpening world, we're very familiar with abrasives. Some people use sandpaper taped to a piece of plate glass or a flat granite tile working from course (say 400) to fine (say P2000 wet). Other people use a wet stone which is basically a block of adhesived together …

Milling In this method of resurfacing asphalt, a milling machine is used to grind down the top course of existing asphalt, typically to a depth of 1.5". The machine utilizes a large rotating drum to remove and grind the pavement surface to the desired depth, and the 'millings' are loaded to a waiting dump truck via conveyor to be hauled ...

What? Micro-milling is the removal of a small thickness (1 inch or less) of existing asphalt concrete prior to placing a surface treatment. The difference between cold milling and micro-milling is the texture left on the existing pavement. Micro-milling provides for a smoother surface than cold milling and is typically used before a slurry seal ...

Steels between 0.15-0.30 wt.% carbon are best machining; above 0.30 wt.% the machinability decreases as carbon content (and hardness) increase. Cold work improves the surface finish attainable (up to a point). Cold drawn bars typically run 50 microinches max and usually arrive at 25-30 microinches in modern processes.

So, milling can drastically improve the driving experience. Milling is also stronger than asphalt paving. In areas that are prone to extreme temperatures, it's a much more resilient material to use. Milling can stand-up to extreme heat and cold in ways regular asphalt can't. It's also more porous than asphalt, which makes it better at ...
