Modeling the Resilient Modulus of Soils

Bearing Capacity of Roads, Railways and Airfields, 2020
Various mathematical models appear in the literature for expressing the relationship between resilient modulus and stress state. In this paper, four mathematical models that are oftentimes cited in the literature are examined and evaluated for their ability to relate resilient modulus and stress.

Grading and frequency dependence of the resilient modulus of ballast

Géotechnique Letters, 2018
The stress–strain and degradation response of railway ballast to imparted train loading is often largely dominated by intrinsic properties, including particle size and particle-size distribution (PSD). To investigate these aspects, a series of large-scale triaxial cyclic tests were conducted on railway ballast.

Solving the Splitting Resilient Modulus of the Asphalt Mixture

Advanced Materials Research, 2011
The finite element software was applied to simulate the splitting test of asphalt mixture, and the computational formula of resilient modulus was fitted out. On the basis of the measured resilient deformation from the splitting test, the computation process of splitting resilient modulus of the asphalt mixture was illustrated in detail.

Resilient modulus of coarse-grained subgrade soil for heavy-haul railway: An experimental study

Soil Dynamics and Earthquake Engineering, 2021
Large-scale dynamic triaxial tests under train-induced repeated load were conducted to study the variation of resilient modulus of the coarse-grained soil under different moisture contents, dynamic stress amplitudes, number of loading cycles and ...

Suction stress effects on stress-dependent resilient modulus of subgrade soils

International Journal on Road Materials and Pavement Design, 2023
Since the resilient modulus is changed by suction and moisture conditions in subgrade soils, these effects should be considered in the model to rationally predict the modulus.

Prediction of the resilient modulus of non-cohesive subgrade soils and unbound subbase materials using a hybrid support vector machine method and colliding bodies optimization algorithm

, 2021
The resilient modulus (MR) of road materials is one of the most important parameters in the analysis and design of pavement. This parameter is used in both empirical methods and mechanistic-empirical methods as the main parameter for expressing the ...

Resilient Modulus and Dynamic Modulus of Warm Mix Asphalt

GeoCongress 2008, 2008
Warm Mix Asphalt (WMA) is produced at temperatures in the range of 30uF to 100uF (17uC to 56uC) lower than the traditional hot mix asphalt (HMA). It has a number of benefits including reducing energy consumption, emissions from burning fuels, and volatiles generated from the heated asphalt binder at the production plant at the paving site.

Resilient Modulus of Cohesive Soils

Journal of Geotechnical and Geoenvironmental Engineering, 1997
Resilient modulus tests were performed on three clayey subgrade soils with repeated-loading triaxial test equipment. For the laboratory-compacted samples, stress at 1% axial strain from the conventional unconfined compression test (Su1.0%) was found to be a good indicator of the resilient modulus (MR).
