Abstract:

The purpose of pavement base and subbase courses is to provide a means for free water to drain from

beneath roadways while providing structural support for the pavement. Problems occur when highway

materials which are assumed to have adequate drainage characteristics actually have low permeability

and low effective porosity.

It has been observed that some base and subbase materials meeting the gradation requirements provide

only fair to poor drainage characteristics. The current gradation ranges permit a broad range of possible

permeability and effective porosities. It is necessary to investigate bases and subbases that satisfy the

current gradation specifications to determine ranges of their permeability and effective porosities.
