Penetration Grade
The penetration grade is used to supply the gravel surface with the purpose of cold or warm asphalt. In this type of road construction, a thin layer of intracranial growth is used to protect the lower surfaces from wet weather, then the rest of the bed is bonded together, making the surface harder to lie on.
