Nonwoven geotextile interlayers for separating cementititious pavement layers: German practice and U.S. field trials

The German highway community has more than 25 years of experience using an alternative interlayer made of a nonwoven geotextile. With proper selection and placement, these interlayers have resulted in excellent performance in separating new concrete pavement layers from the cementitious bases commonplace on the German motorway system. While this application also exists in the United States, the possibility of using the nonwoven geotextile as a separation interlayer in an unbonded concrete overlay system has also generated significant interest because of the potential cost savings involved. This report documents the German experience and gleans better practices for using nonwoven geotextile interlayers between cementitious layers in the United States. The report covers field trials in Missouri and Oklahoma along with other information so that pavement engineers can make an informed decision on the viability of this innovative but proven alternative.
