<p><p><strong>References:</strong></p><p><strong>Method Summary</strong></p><p>For granular lightweight fills, test sections are desirable at the start of construction to confirm or determine the number of passes required for compaction. This is especially important for shredded tire and wood fiber fills where typical density testing cannot be conducted.</p><p><strong> </strong><strong>Accuracy and Precision</strong></p><p>This method is an accurate way to establish methods for fill placement, provided that the test section is properly monitored and that the site conditions and construction practices are the same as those used during production.</p><p><strong> </strong><strong>Adequacy of Coverage</strong></p><p>Assuming the rest of the project is constructed under similar conditions and with the same methods, the test section will accurately represent the entire site.</p><p><strong> </strong><strong>Implementation Requirements </strong></p><p>Although construction of test sections may seem to delay projects initially, determination of the most appropriate placement and compaction techniques often leads to more efficient construction and lower total costs.</p><p><strong> </strong><strong>General Comments</strong></p><p>Test sections can be very important for determining compaction methods on all projects that use shredded tire, wood fiber, or other lightweight granular fills that cannot be easily tested using standard procedures that have been developed for earth fills.</p></p>
