Early Permeability Test for Asphalt Acceptance

Early Permeability Test for Asphalt Acceptance One of the primary assumptions in structural pavement design for conventional pavements is that a flexible (hot mix asphalt) pavement be impermeable. The basis for this design approach is to minimize moisture infiltration and thus maintain adequate support from the underlying unbound materials.

A Method for Measuring the Air Permeabilities of Asphalt ...

The permeability of asphalt-concrete pavements to air and water appears to be a primary factor in controlling pavement durability. Early investigators (Hveem (1) and McKesson (2)) were concerned with obtaining permeabilities low enough to prevent liquid water from entering the base but, at the same time, high enough to allow water vapor to escape.
