<p><p><strong>References:<br></strong><em>Eaton and Berg (1980)<br>Elseifi (2003)</em></p><p><strong>Method Summary </strong></p><p>The soil strain gauges are installed within the encapsulated soil. 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. The selection of the strain gauge is a compromise based on different decision criteria (Elseifi 2003).</p><p><strong>Accuracy and Precision</strong></p><p>The soil strain measurement provides the strain in the soil due to the loading conditions and environmental changes. It is generally accurate and precise if appropriately installed. However, this method is not suitable for assessing the quality of construction.</p><p><strong>Adequacy of Coverage</strong></p><p>This method requires a significant amount of instrumentation to cover a wide pavement area.</p><p><strong>Implementation Requirements </strong></p><p>Soil strain gauges and measuring devices are required to implement this method.</p><p><strong>General Comments</strong></p><p>The soil strain measurement is a quality assurance tool for the effectiveness of the partial encapsulation during service.</p></p>
