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.

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).

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 ...

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 ...

Predicting the Resilient Modulus of Asphalt Concrete from the Dynamic Modulus
Transportation Research Record: Journal of the Transportation Research Board, 2007The 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. This paper presents an analytical method of calculating the

Experimental Study on Static and Dynamic Compressive Resilient Modulus
Journal of Highway and Transportation Research and Development (English Edition), 2020To study the effect law of asphalt mixture composition design and static/dynamic test methods on resilient modulus, and consummate the design parameters of asphalt mixture, the laboratory tests on static/dynamic compression resilient moduli and strength are conducted by the uniaxial unconfined method and top measuring method by MTS-810.

The Use of Dynamic Cone Penetrometer to Predict Resilient Modulus of Subgrade Soils
Advances in Pavement Engineering, 2005The 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.
