Study on Rebound Deformation Behavior of Sand-Gravel Material
Publication: Road Pavement Material Characterization and Rehabilitation: Selected Papers from the 2009 GeoHunan International Conference
Abstract
The sand-gravel materials have a nonlinear behavior, the resilient modulus can describe the behavior effectively, and the resilient modulus model can be attained through enlarged bearing plate test. By analyzing the limitations of traditional bearing plate test with measuring the rebound deformation property of sand-gravel material, the experimental apparatus was ameliorated. Based on the test data of enlarged bearing plate test, the fitting result shows that the L-H model can effectively display nonlinear rebound deformation behavior of sand-gravel material, and the regression coefficient has relation with gradation of sand-gravel and clay, water content, compactness. Two important parameters of influencing resilient modulus of sand-gravel material, gradation of sand-gravel and clay and water content, are analyzed. Corresponding engineering suggestions are put forward.
