In this study, a comprehensive laboratory testing program was designed to study the resilience characteristics of unbound granular materials (aggregate base coarse) using repeated load triaxial test (RLTT). During experimental program, resilient modulus material examined different moisture content levels, gradation Fuller’s equation, and stress levels. The results show that content, gradation, ...

This research was carried out to assess the effect of aggregate skeleton, temperature variation, and loading duration on resilient modulus asphalt concrete mixtures. Two different gradation methods, i.e., conventional method Bailey gradation, were adopted design skeleton. The these with duration, has not been previously investigated. Modified Marshall Test used determine optimum binder content ...

The new Mechanistic-Empirical Pavement Design Guide (MEPDG) uses the subgrade resilient modulus (MR) as key input parameter to represent soil behavior for pavement design. increases with an increase in confining pressure, whereas, deviatoric stress, it granular soils and decreases fine-grained soils. value of MR is highly stress dependent, state (i.e., bulk stress) a function position materials...

The low load-bearing capacity of subgrade soils is typical for forest roads. For the determination resilient modulus Mr unbound natural as well recycled materials, a laboratory triaxial test with cyclic loading generally preferred. volume roads, including an alternative method CBR test, which uses standard devices repeated loading, being tested and applied in practice. soils, procedure determin...
