Resilient Modulus for Unsaturated Unbound Materials

Road Materials and Pavement Design, 2011
ABSTRACT The suitability of the current resilient modulus test protocol (NCHRP 1-28A) for its application to unsaturated soils was assessed. Modifications to the stress state conditions of the protocol are necessary due to the axis-translation needed during the test when measuring matrix suction.

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).

Modeling the Resilient Modulus of Soils

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.

Resilient Modulus for EPS Geofoam

Soil and Material Inputs for Mechanistic-Empirical Pavement Design, 2007
Most of the current design methods for geofoam used in pavement structures adopt the allowable working stress concept. These design methods do not fit rationally in conventional pavement design practice such as the AASHTO pavement design guide. To design flexible pavement structures according to AASHTO, the resilient modulus, M r , for EPS geofoam ...

Predicting the Resilient Modulus of Asphalt Concrete from the Dynamic Modulus

Transportation Research Record: Journal of the Transportation Research Board, 2007
The NCHRP 1-37A Guide for Mechanistic-Empirical Design of New and Rehabilitated Design Structures introduces the dynamic modulus as the material property to characterize asphalt concrete. This is a significant change from the resilient modulus used in the previous AASHTO pavement design guide.

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).
