Abstract
Iowa DOT has implemented a newer technique for road construction that incorporates a layer of geotextile fabric between the original concrete and the newly poured overlay, an alternative to using an asphalt cement concrete layer. Although previous studies have demonstrated positive performance results for the roads built with geotextile fabric, questions remain about their long-term performance. Researchers conducted load tests on sections of a road in Buchanan County built with a geotextile fabric interlayer, demonstrating a new method for on-site road performance assessment and generating comparison data for different thicknesses and manufacturers of geotextiles.
