Use of Non-Woven Fabric Interlayer for Unbonded Concrete Overlays

Principal Investigator(s):

Lev Khazanovich, Former Professor, Civil, Environmental and Geo-Engineering

Project summary:

MnDOT is investing more of its programs into long-term fixes such as unbonded overlays. This non-woven fabric product has the potential to save money on these projects, but the long term performance is not known. Through Minne-ALF testing, this project helps to answer that question, providing MnDOT with guidance on the use of this product.
