Layers in the construction of a mortarless pavement: A.) Subgrade B.) Subbase C.) Base course D.) Paver base E.) Pavers F.) Fine-grained sand. In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement ...
The joints in concrete pavement is another source of issue. In a certain type of road (concrete, asphalt or gravel), the thickness of layers and type of materials used in base, sub-base and pavement layer matters. Sometimes these attributes are expressed via an aggregated measure called granular base equivalence (GBE). [2] [3]
The base course or basecourse in pavements is a layer of material in an asphalt roadway, race track, riding arena, or sporting field. It is located under the surface layer consisting of the wearing course and sometimes an extra binder course. If there is a sub-base course, the base course is constructed directly above this layer.

Fine-grained sand Section through railway track and foundation showing the sub-grade. In transport engineering, subgrade is the native material underneath a constructed road, [1] pavement or railway track (US: railroad track).

A granular surface can be used with a traffic volume where the annual average daily traffic is 1,200 vehicles per day or less. [citation needed] There is some structural strength if the road surface combines a sub base and base and is topped with a double-graded seal aggregate with emulsion.
So we look at '24 in the context over the last four years, and we say, OK, Frito-Lay, and the category has grown above our long-term expectations of Frito-Lay grew 8% in the last four years, that ...
Paver base is a form of aggregate used in the construction of patios and walkways whose topmost layer consists of mortarless (or "dry-laid") pavers. The first layer in the construction of such a surface is called the subgrade —this is the layer of native material underneath the intended surface.
