Evaluation of in-service subgrade resilient modulus with consideration of seasonal effects

The resilient modulus (M;Five cohesive soils and a dune sand sampled from in-service subgrades in Indiana were tested. The procedures were developed to establish M;An unique relationship between M;A significant reduction in M;Vibratory compacted dune sand shows better resilient response than impact compacted sand. Resilient characteristics of dune sand are not affected by water content, while permanent deformation under repeated loads increases as water content increases.;Procedures to estimate M...
