Effects of Aggregate Gradation on Resilient Modulus and CBR in Unbound Granular Materials
Resilient modulus and California Bearing Ratio (CBR) in unbound granular materials are the key technical characteristics of layers in a flexible pavement design. Among the factors affecting these two parameters, the aggregate gradation is the most important. Using particle size distribution curve developed by AASHTO, together with other considerations mentioned in the related regulations have y...
متن کاملEstimation of Subgrade Resilient Modulus Using Unconfined Compression Test
1 2 Resilient modulus test is the recommended test to characterize subgrade soil for 3 pavement design in 1993 AASHTO pavement design guide as well as new proposed 4 Mechanistic-Empirical Pavement Design Guide (MEPDG). This test requires significant 5 resources including high level of technical capability to conduct. For smaller projects where 6 costly and complex resilient modulus testing is n...
متن کاملEstimation of Subgrade Resilient Modulus Using the Unconfined Compression Test
To facilitate pavement design, the new proposed mechanistic-empirical pavement design guide recommends the resilient modulus to characterize subgrade soil and its use for calculating pavement responses attributable to traffic and environmental loading. Although resilient modulus values could be determined through laboratory testing of actual subgrade soil samples, such testing would require sig...
متن کاملShakedown of unbound granular material
Compacted unbound granular materials are extensively used as sub-layer in pavement design. Most pavement design guides assume that they are responsible for the degradation and deformation of the roads and railways that they support. Biaxial tests are usually employed to investigate the elasto-plastic response of these materials to cyclic loading. A particularly interesting question is whether a...
