Permeable subbase courses are becoming more prevalent because of their ability to drain infiltrating water from the surface.

In topology, a collection of sets which generate the topology is called a subbase.

Water trapped under the pavement softens the subbase and subgrade, making the road more vulnerable to traffic loads.

The converse fails, since generally the cylinder sets will only form a subbase (and not a base) for the initial topology.

Environmental factors include heat and cold, the presence of water in the subbase or subgrade soil underlying the pavement, and frost heaves.

Concrete is a rigid pavement, which can take heavier loads but is more expensive and requires more carefully prepared subbase.

When building a three layer flexible pavement, the subbase layer is not used and the base course is placed directly on the natural subgrade.
