<p><p><h2>Project Summary/Scope:</h2>One section at the Virginia Smart Road was instrumented and constructed to quantify its effectiveness as a moisture barrier. In Section J, a geocomposite membrane was installed underneath an asphalt-treated drainage layer to test the membrane’s effectiveness as a moisture barrier.</p><p>Prior to the installation of the geocomposite membrane, a 75-mm 21-B granular subbase was installed in Section J. This is a common environment for the placement of a moisture barrier.

Electronic devices record the soil strain. Eaton and Berg (1980) mentioned the use of soil strain gauges to determine the amount of frost heaving caused by freezing of the encapsulated layers. This strain measurement can be used as a quality assurance tool.
