Effect of bell-shaped loading and haversine loading on the dynamic modulus and resilient modulus of asphalt mixtures

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.

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).

Revisiting the relationship of dynamic and resilient modulus test for asphaltic concrete mixtures

Construction and Building Materials, 2018
Mechanistic-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 ...

Experimental study of dynamic resilient modulus of subgrade soils under coupling of freeze-thaw cycles and dynamic load

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 ...
