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.

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.

Resilient modulus properties of granular highway materials

Canadian Journal of Civil Engineering, 2009
An essential component of the new Guide for mechanistic–empirical design of new and rehabilitated pavement structures for the design of flexible pavement structures is the use of resilient modulus for base / subbase materials and subgrade soils. This study reports on resilient modulus (Mr) test results for unbound pavement materials that were obtained

Resilient Modulus Testing for Pavement Components

2003
Description Nineteen peer-reviewed papers address the latest issues affecting the resilient modulus test and use of the test results. Resilient modulus indicates the stiffness of a soil under controlled confinement conditions and repeated loading.

Prediction of the resilient modulus of two tropical subgrade soils considering unsaturated conditions

, 2020
The resilient modulus (MR) is essential for the understanding of pavement response to climate effects, and to seasonal fluctuations of water content and matric suction.

Analysis on the seasonal effect of subgrade resilient modulus

2010 International Conference on Mechanic Automation and Control Engineering, 2010
The paper first analyzes the seasonal variation law of subgrade resilient modulus and water content, and then summarizes the common quantitative adjustment methods, calculation of the equivalence of resilient modulus based upon damage equivalence, for resilient modulus of subgrade in the process of season alterations.

Effect of geogrid on deformation response and resilient modulus of railroad ballast under cyclic loading

, 2020
Laboratory investigations were carried out using process simulation test (PST) apparatus to assess the role of geogrid on the deformation response and resilient modulus of railroad ballast at different loading frequencies (f) varying from 10 to 40 Hz ...

Application of artificial neural network models for predicting the resilient modulus of recycled aggregates

International Journal of Pavement Engineering, 2020
In recent years, efforts have been made to utilise construction and demolition (C&D) wastes as an alternative material to natural quarried aggregates in the structural layers of railways and roads.
