Resilient modulus modelling of unsaturated subgrade soils: laboratory investigation of silty sand subgrade

Road Materials and Pavement Design, 2015
In flexible pavement structures, stiffness of unbound granular layers and subgrade soil significantly contribute to the overall performance of the pavement system.

Prediction of subgrade resilient modulus using artificial neural network

KSCE Journal of Civil Engineering, 2014
The development of an Artificial Neural Network (ANN) model to estimate subgrade resilient modulus is described in this paper. Nine (9) different sources of subgrade materials locally available in Georgia were subjected to the resilient modulus test with

Correlation between Subgrade Reaction Modulus and CBR for Airport Pavement Subgrades

T&DI Congress 2014, 2014
Subgrade characterization plays a key role in the thickness design of airport pavements. From a mechanical point of view, a subgrade soil represents a highly diverse heterogeneous structure. The usual practical way to deal with heterogeneous composites is to average their mechanical properties over the material volume.

Design Subgrade Resilient Modulus for Florida Subgrade Soils

2003
Many agencies still use empirical correlations developed to determine design subgrade resilient modulus based on California Bearing Ratio (CBR), R-Value or Soil Support Value (SSV) for pavement design projects. These relationships do not consider the stress dependency of the laboratory determined resilient modulus value. Backcalculated subgrade modulus

Trapezoidal footings on non‐linear subgrades

International Journal for Numerical and Analytical Methods in Geomechanics, 1984
AbstractThe pressure versus settlement response is highly non‐linear for soils, in general. In the present study, a cubic equation of the type p = K1w − K2w3 is suggested to incorporate the non‐linear behaviour. A trapezoidal footing with constant depth resting on a subgrade having non‐linear response is analysed.
