Resilient Modulus and Dynamic Poisson's Ratio of Asphaltic Concrete Mixes [PDF]

, 1976
Increased interest in rational approaches to flexible pavement design, rather than the usual empirical methods, has brought about an urgent need for a better understanding of the material properties involved. In this study, laboratory equipment capable of providing reliable measurements of the material properties for asphaltic concrete mixes, under ...

Backcalculation of dynamic modulus from resilient modulus test data

Canadian Journal of Civil Engineering, 2011
For the past few decades, the stiffness of asphalt material has been commonly characterized by means of resilient modulus. However, the resilient modulus is not a fundamental material property, and hence, the concept of resilient modulus has been subsequently diminished in the latest Mechanistic-Empirical Pavement Design Guide (MEPDG).

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 ...

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.

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.
