Performance Evaluation of Wicking Geotextiles for Improving Drainage and Stiffness of Road Foundation

Status: Developing RFP

Project overview

Evaluate performance benefits (e.g., maintaining stiffness, improving drainage, and stabilizing moisture profile) of relatively recent developed single-layer wicking geosynthetic. Construction observation, design analysis, field testing and instrumentation are to be planned for reconstruction of selected MnROAD test cells (Cell 4, 15, and others TBD). Additionally, an accelerated laboratory load testing program is planned. Program will simulate trafficking to determine load-deformation response with controlled drainage/wicking. Research studies on this technology are limited and what is available focuses on only the drainage capabilities and short-term performance.
