Abstract
Numerous embodiments of a synthetic drainable base course ('SDBC'), and paved structures that may advantageously include an SDBC, are provided. As a key advantage of SDBC's according to the invention, they are of sufficient capacities and structural strength to be used within layered paved structures such as highways, airport runways and parking lots, to provide drainage superior to that afforded by conventional means and methods involving the use of open graded base courses that are typically formed of natural soils and aggregate and are extremely expensive to install. The invention includes means and methods that use conventional heavy equipment for installing an SDBC during the construction of a roadway or other paved surface.
