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 Roadbed Soil Dynamic Resilient Modulus Test

Advanced Materials Research, 2013
This paper draws on the successful experience from domestic and abroad researches, testing repeatedly of powder subgrade with load triaxial tests, analyzing the relationship between the subgrade soil resilient modulus, deviatoric stress, water content and degree of compaction.

Experimental Study of Dynamic Resilient Modulus of Cohesive Soils in Henan

Advanced Materials Research, 2014
Subgrade soil is very important materials to support highways. Resilient modulus (MR) has been used for characterizing stress-strain behavior of base or subbase subjected to repeated traffic loadings. Several methods to estimate the resilient modulus were suggested in the past years. The main objective of this study was to test the resilient modulus in

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.

Comparing Resilient Modulus and Dynamic Modulus of Hot-Mix Asphalt as Material Properties for Flexible Pavement Design

Transportation Research Record: Journal of the Transportation Research Board, 2006
With the current trend toward developing mechanistic flexible pavement design and the need for more reliable design procedures, accurate characterization of hot-mix asphalt (HMA) properties is needed. Resilient and dynamic modulus tests were performed at five temperatures on two typical mixes used in the Commonwealth of Virginia to compare the test ...

The Use of Dynamic Cone Penetrometer to Predict Resilient Modulus of Subgrade Soils

Advances in Pavement Engineering, 2005
The resilient modulus is used in the characterization of base and subgrade soils and in the design of pavement structures. The resilient modulus of subgrade soils can be estimated by using expensive and time-consuming laboratory test results or from overestimated backcalculated values from nondestructive test results.

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.
