Question about the roads we drive on?

Question

ok well obvously some are just plain black tar. but what bout the one that are black but have the rocks in them do they puor the tar over the rocks?

Answer 1

Tar is spread on the road surface in a thin layer and into the surface of the liquid tar is shoveled sand or gravel. The tar has the effect of sealing the surface so that less water leaks into the roadbed and of holding the sand or rock in place.

Answer 2

I don't know of any tar roads. tar and rocks are mixed together
