Influence of Degree of Saturation (DOS) on Dynamic Behavior of Unbound Granular Materials

The extensive application of natural unbound granular materials (UGMs) motivates studies into the mechanical properties alternatives such as processed crushed rocks employed commonly base or subbase layers. rutting and settlement generated in layers is widely restricted many specifications standards. In this research, dynamic behavior including resilient modulus (Mr) plastic strain (??p) collected from Queensland Australia will be tested by a series repeated load triaxial test (RLT) tests to investigate UGMs under fluctuation degree saturation (DOS) (59%–100%). particular, RLT specimens were prepared laboratory through proper gradation optimum moisture content (OMC) 100% standard proctor maximum dry unit weight. Results showed that UGM soaked at higher DOS lower weaker resistance heavy traffic volumes with significant accumulation strain. Mr ??p aggregates different cyclic deviator stresses 425 kPa 625 approximately linearly decreased increased certain number cycles up 50,000, respectively.
