waste slag from blast furnaces is used for road surfacing.
Bitumen
Asphalt roads look similar in nature to concrete because both use an aggregate material consisting of rocks to make up as much as 60% of the volume of the final solid material.
The four-letter word you're looking for is "pave." It refers to the process of covering a road with a hard surface, typically using materials like asphalt or concrete to create a durable driving surface.
Asphalt, also known as bitumen, is the sticky, black and highly viscous liquid or semi-solid present in most crude petroleums and in some natural deposits; it is a substance classed as a pitch. Until the 20th century, the term asphaltum was also used.The primary use of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete.

According to Merriam Webster the definition of surfacing is: material forming or used to form a surface. Surfacing is a noun. 1861 is the first known use for the word surfacing.
Tarmac is not a rock by definition. It is a type of material used in road surfacing, consisting of crushed rock, tar, and bitumen. The term "tarmac" is often used colloquially to refer to paved road surfaces.
It has been done . La Guardia Airport and arguably the older Brooklyn Flats Proving Grounds had runways built on, with heavy surfacing, a platform of waste material, or if you will garbage.
Tarmac is not a rock; it is a man-made material used for surfacing roads, driveways, and parking lots. It is a mixture of asphalt and aggregate materials that form a smooth and durable surface. Tarmac is not impermeable and can allow some water to pass through its surface.
Tarmac, short for tarmacadam, was patented in the 19th century by Scottish engineer John Loudon McAdam. It is a road surfacing material made of crushed stone mixed with tar or bitumen, primarily used for surfacing roads and pavements.

"Paving" comes to mind; there are other possibilities, no doubt.
Not enough information in your question. It will depend on multiple factors, like vehicle weight, vehicle condition, tire condition, road surfacing and type of road surfacing, driver reaction speed.

No, but you often have bits of hard material surfacing in the socket which you can pick out. You would be forgiven for thinking it's bone. Your tooth is actually sort of cemented into the bone, for want of a better description, and it's bits of this material that you are seeing. I have personally had bits surfacing for a week after.
