Development And Proposed Implementation Of A Field Permeability Test For Asphalt Concrete, David L. Allen, David B. Schultz Jr., L. John Fleckenstein

Kentucky Transportation Center Research Report

Pavement drainage contributes greatly to long-term pavement performance. Pavements undergo surface, as well as subsurface, drainage during prolonged rain events. It is this subsurface drainage that is of concern in this study. In the advanced asphalt pavements of today, where a drainage layer may be incorporated to facilitate the movement of water out of the above overlying pavement layers, water can be a problem in areas with variable permeability. High permeability may also cause other problems related to drainage such as frost heave, stripping, asphalt emulsification, and water coming out of the pavement surface from deeper layers in the pavement …
