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.

Study on Morphological Parameters of Hysteretic Curve of Dynamic Resilient Modulus

Journal of Highway and Transportation Research and Development (English Edition), 2020
The hysteresis curve of dynamic resilient modulus (DRM) is the load and deformation curve of asphalt mixture under dynamic loading, it can reflect the evolution rule of internal stress-train state with load and temperature. Based on viscoelastic theory, 3 morphological parameters could be determined: slope k of major axis, eccentricity e of ellipse ...

Automated Dynamic Cone Penetrometer for Subgrade Resilient Modulus Characterization

Transportation Research Record: Journal of the Transportation Research Board, 2002
Subgrade soil characterization, expressed as resilient modulus ( M R ), is crucial for pavement design. For a new design, M R is generally obtained by conducting repeated triaxial tests on reconstituted and undisturbed cylindrical specimens.

Resilient Modulus Prediction of Subgrade Soil Using Dynamic Cone Penetrometer

2018
Stress-strain response of pavement structure is commonly presented with resilient modulus (Mr). Resilient behavior of subgrade soils is measured using expensive laboratory tests, that is somewhat time-consuming. Design engineers sometimes, uses overestimated backcalculated values from non-destructive test, which in turn lead to over-design of pavement.

Experimental Investigation on Dynamic Resilient Modulus of Lime Stabilized Clay Soil

2018
To investigate the dynamic resilient modulus of lime soil, and find out the law of resilient modulus decay under freeze-thaw cycle, adapting to the new design code and maintenance system of highway subgrade in China, a series of dynamic tests were carried out according to the standard laboratory test methods (JTG D30-2015).

Study on Prediction Model of Dynamic Resilient Modulus of Cohesive Subgrade Soils Considering Moisture Variation

Applied Mechanics and Materials, 2014
The matric suctions were measured by the filter paper method, and the parameters of soil-water characteristic curve were obtained. In order to investigate the effect of moisture content on cohesive subgrade soils dynamic resilient modulus, a series of dynamic-triaxial test were carried out.

Nonlinear Interpretation of Resilient Modulus Parameters Considering Incremental Static and Dynamic Loading

Transportation Research Record: Journal of the Transportation Research Board
The resilient modulus ( M r ) is typically interpreted as the average of the last five secant slopes of the cyclic stress-axial resilient strain curve from repeated loading triaxial tests.
