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.

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 ...

Construction and Building Materials, 2018
Abstract The vertical compressive stress pulse distributions at various asphalt pavement depths can be represented as square loading, haversine loading and bell-shaped loading. This study aims in comparing the effects of bell-shaped loading and haversine loading on the dynamic modulus and resilient modulus of asphalt mixtures.

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.

Revisiting the relationship of dynamic and resilient modulus test for asphaltic concrete mixtures
Construction and Building Materials, 2018Mechanistic-Empirical Pavement Design is considered relatively more effective than conventional empirical design for excessive tyre pressure exerted by axle load spectra and diverse environmental conditions. Many highway agencies are adopting a paradigm shift to Mechanistic-Empirical pavement design practices, obsoleting huge inventories of resilient ...

Journal of Central South University, 2020
Although the dynamic properties of subgrade soils in seasonally frozen areas have already been studied, few researchers have considered the influence of shallow groundwater during the freeze-thaw (F-T) cycles. So a multifunctional F-T cycle system was developed to imitate the groundwater recharge in the subgrade during the freezing process and a large ...

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, 2011For 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).
