Resilient Modulus for Fine‐Grained Subgrade Soils

Journal of Geotechnical Engineering, 1994
A method has been developed for the estimation of resilient modulus of compacted fine-grained subgrade soils. The method takes into account the influence of soil physical state, stress state, and soil type. The effect of soil physical state is quantified by combinations of two equations relating resilient modulus to moisture content.

Resilient Modulus Testing of Lean Emulsified Bases

Transportation Research Record: Journal of the Transportation Research Board, 1996
A research study conducted jointly by the Wyoming Department of Transportation and the University of Wyoming examined the effect of low emulsified base treatment on resilient modulus values. The study involved selecting two types of aggregate, treating duplicate samples with variable amounts of emulsified asphalt, and performing resilient modulus ...

Backcalculated and Laboratory-Measured Resilient Modulus Values

Transportation Research Record: Journal of the Transportation Research Board, 2009
The resilient modulus ( MR) of roadbed soils is a necessary parameter in pavement design. The MR of roadbed soils is dependent on the soil type, water content, dry density, particle gradation, Atterberg limits, and stress states. Several procedures can be used for the determination of the MR: laboratory testing, backcalculation with nondestructive ...

Resilient Modulus Modeling with Information Theory Approach

International Journal of Geomechanics, 2013
AbstractStatistical models have been developed to correlate resilient modulus with routine properties of subgrade soils and state of stress for pavement design application. An information theory approach is taken as a method in ranking models. This approach is compared with the R2 approach.

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 — Pavement Subgrade Design Value

2003
Much resilient modulus research work has been completed recently, mostly as part of the Long Term Pavement Performance (LTPP) study. This work has led towards the adoption of the resilient modulus test procedure, T307-99, in the current release of the American Association of State Highway and Transportation Officials (AASHTO) Tests.

PREDICTION TOOLS FOR SUBGRADE RESILIENT MODULUS

Resilient Modulus (MR) is a fundamental parameter in the Mechanistic-Empirical Pavement Design Guide (MEPDG) that characterizes the stiffness of subgrade soils under repeated traffic loads. Traditionally, MR determination involves direct laboratory testing, which can be labor-intensive, costly, and impractical for large-scale pavement projects or ...

Correlation between resilient modulus (M) and constrained modulus (M) values of granular materials

Construction and Building Materials, 2018
Abstract The resilient modulus (MR) value of unbound aggregates has been widely accepted as the principal mechanical property required in the mechanistic-empirical design/analysis of pavement structures. Resilient modulus measured through repeated triaxial load test is highly desirable to characterise granular materials.

Repeatability of the Resilient Modulus Test Procedure

2003
Through the work of the Strategic Highway Research Program (SHRP, 1987–1992) and the Federal Highway Administration (FHWA, 1992-present), the government has provided financial and technical assistance to develop and improve a laboratory test method to determine the resilient modulus properties of unbound materials.

Resilient Modulus of Compacted Crushed Stone Aggregate Bases

2007
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 result of a trend in pavement design of using mechanistic models.
