dc.description | Abstract: The Strategic Highway Research Program, managed by the Federal Highway Administration, includes a pavement evaluation component as part of its Long-Term Pavement Performance study. These evaluations include the use of falling-weight deflectometer (FWD) test devices. The purpose of this project was to determine whether the FWD test procedures could be modified to reduce cost, without losing a significant amount of information. Procedural changes could include a decrease in the number of test replicates and/or an increase in the spacing between test stations. Variability between replicates was found to be relatively low; a reduction in replicate drops from four to two would not cause a substantial loss in information. An increase in spacing between tests from 7.6 m (25ft) to 30.5 m (100ft) would result in a substantial loss ofinfonnation. An increase in spacing from 7.6 m (25ft) to 15.2 m (50ft) would be reasonable if test section responses to FWD were to be summarized as expected values and dispersions. If extremes in pavement response (e.g., minimum and/or maximum stiffness) were judged to be the most important results, the spacing between tests should not be increased from 7.6 m (25ft). | - |
