Resilient Modulus of Kentucky Soils

2001
In recent years, the American Association of State Highway Transportation Officials (AASHTO) has recommended the use of resilient modulus for characterizing highway materials for pavement design. This recommendation evolved as of a result of a trend in pavement design of using mechanistic models, which are based on the theory of elasticity (layered ...

Resilient Modulus Backcalculation Techniques for Track

Performance Confirmation of Constructed Geotechnical Facilities, 2000
The layer moduli of track substructure components are important factors in the evaluation of track condition and estimation of maintenance costs. Layer moduli can be estimated from in-situ tests such as the cone penetration test (CPT); however, for layers of open graded aggregate, such as railway ballast with large individual particles, the results of ...

Resilient Modulus of Cement-Stabilized Phosphogypsum

Journal of Materials in Civil Engineering, 1996
This paper presents the findings of a preliminary study of the dependence of resilient modulus of cement-stabilized phosphogypsum on various material parameters. In particular, the dependence of the resilient modulus on cement content, dry unit weight, moisture content, and curing time was determined.

A simple chart for the prediction of resilient modulus

Géotechnique, 1976
Considerable effort has been put into the task of obtaining characterization of pavement materials, and the laboratory equipment necessary for this task is both expensive and complex. This note presents a method of overcoming this problem for partially saturated cohesive subgrades.

Extracting Damping Information from Resilient Modulus Tests

Journal of Materials in Civil Engineering, 2017
AbstractIn addition to the dynamic moduli, the damping properties of the different pavement layers are required by most algorithms used for modeling the dynamic responses of pavement caused by movi...

Modulus of resilience as predictor for clinical wear of restorative resins

Dental Materials, 1992
Eight posterior restorative resins were tested with respect to flexural strength, modulus of elasticity, and modulus of resilience. The mechanical properties were correlated to the two-year results of clinical wear tests. Linear relationships were found between flexural strength and clinical wear and between modulus of resilience and clinical wear.

Construction of Dynamic Modulus Master Curves with Resilient Modulus and Creep Test Data

Transportation Research Record: Journal of the Transportation Research Board, 2012
For the past few decades, the stiffness of materials used for roadway design and construction has been commonly characterized by the resilient modulus, defined as the ratio of the applied stress to the recoverable strain. However, the resilient modulus is not a fundamental material property of a viscoelastic material.

Resilient Modulus Models for Compacted Cohesive Soils

Transportation Research Record: Journal of the Transportation Research Board, 2004
Three-parameter models have been used to represent the effects of confining and shear stresses on the value of resilient modulus. A new generation of such models allows better characterization of the variation of resilient modulus at low deviator stress. These models can be extended to incorporate the effects of soil type, soil structure, and the soil

An Investigation on Resilient Modulus of Bituminous Mixtures

2019
IRC:37-2012 suggests to use resilient modulus as an input parameter in the design of bituminous pavements in India. IRC:37 specifies the values of resilient modulus at different temperatures for Bituminous Concrete (BC) and Dense Bituminous Macadam (DBM) mixes with various grades of unmodified and modified binders.

Weighting Factor for Seasonal Subgrade Resilient Modulus

Transportation Research Record: Journal of the Transportation Research Board, 1998
Subgrade resilient modulus is highly dependent on water content, which can vary significantly with a number of seasonal environmental factors. Because the determination of seasonal resilient modulus is cumbersome, it is difficult to include environmental factors in pavement design.
