Study Description
Objectives
This project will explore the effectiveness of a geocomposite capillary barrier drain to 1) divert infiltrating water from reaching pavement subgrades and 2) prevent the upward capillary flow of water into pavement base courses during freezing. This effort is directed at reducing the total amount of water and length of time that water persists in unbound base courses and in reducing the total amount of water in subgrades.
Comments
Ongoing. An interagency agreement was executed between FHWA and CRREL to transfer the State funds to CRREL so it may perform the research. Funds are also being provided by the National Cooperative Highway Research Program (NCHRP) Innovations Deserving Exploratory Analysis Program (IDEA). A draft of this final report - Geocomposite Capillary Barrier Drain for Limiting Moisture Changes in Pavement Subgrades and Bases For the period March/2000 through June/2001 (PDF File) - is currently available. Researchers are also considering freezing the test section, as it is now, to determine the infulence of the capillary barrier on frost heave and water migration from the subgrade into the base (and vice versa). A meeting at CRREL headquarters is tentatively scheduled for Sept/Oct 2002 timeframe. A draft report will also be submitted by CRREL shortly. (2/04/02)
