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

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.

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.

Cold Weather Subgrade Stabilization

Soil Improvement, 2007
This paper describes an approach to cold-weather subgrade stabilization. Background information was derived from the open literature, ongoing research and discussions with stakeholders in industry, academia and the government. Traditional subgrade stabilization in road construction is defined herein as the use of unmodified lime, cement or fly ash in ...

Evaluation of Subgrade Compactness

Applied Mechanics and Materials, 2013
Subgrade compactness is the assurance of road strength and stability requirements, is an important indicator of the quality control of road works. Summarize the subgrade compaction detection methods. Expound the inspection and assessment of the compactness methods and precautions combined with the new specification can provide technical reference.
