I've seen so many different ways of doing this. From sheeps foot rollers to high hoes to grinders.
This is cool!

The GIF seems to be speeded up. I would like to see the blade configuration that makes that possible.
I agree. If that is a regular blade say goodbye to the top rather quickly. Plus that was awfully pliable pavement.Quote:

A good grader operator would know how to rotate the blade 180°from normal as if he were going to grade while driving in reverse. Most graders can lay the blade down quite a bit Almost to horizontal. If you watch the vid in stop action the blade is not spun 180° so he is not using the cutting edge. But there is almost a brief glimpse of something that could be an attachment to the top of the blade with a cutting edge It is nearly impossible to see, and I could be mistaken about it even being there.Quote:

Yup. Agree. Been around a few graders. Never operated. Just observed. And I agree about some kind of attachment.Quote:

is "pavement" code for asphalt or some other bitumen composite material? - the broken edges are more black than grey, so I was thinking it was asphalt over a road base bed.
Basically yes. Asphalt is a better term.Quote:

The word pavement is used to describe the surface that is created by the paving process. The pavement itself can be any of or a combinations of many various materials; gravel, cobble stone, flag stone, fired clay brick, concrete brick, stone brick, poured concrete, the list goes on.
To control weeds, prevent mud, and to keep from compacting the soil over tree roots, I "pave" the walking paths in my woods and garden with wood chips from trimming the trees.
In addition, I am sure there is some confusion about the meaning of some of the terms. For example, there are at least 23 different types of concrete. At least 9 of which are commonly used in road construction. In this thread we are actually discussing #20 on the list of concrete types. Or possibly #10.1, 10.2, or 10.3.
I believe that video shows Asphalt Concrete pavement being removed. This paving material, commonly called asphalt in the USA, is made from bitumen (the glue) and aggregate (gravel). It is a relatively flexible material especially in warm weather. If you watch closely when a heavy truck drives by, the road surface actually dips and rebounds as the tires roll over the surface. At intersections, where traffic stops, then accelerate away, many times the cross marking lines are "bent" where all of the tires slowly "push" the road surface backward each time one passes over the line.
In the video the surface of the road was black when it was first laid down. Over the years traffic wears away the black bitumen from the surface, exposing the lighter colored aggregate. Dirt and other debris also gets stuck to the black bitumen between the aggregate giving it a gray color. The cut surface looks more black because the cutting process leaves a clean surface with a higher percentage of black from the bitumen below the road surface. .
