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.

Revisiting the relationship of dynamic and resilient modulus test for asphaltic concrete mixtures
Construction and Building Materials, 2018Abstract 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 ...

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.

Experimental Investigation on Dynamic Resilient Modulus of Lime Stabilized Clay Soil
2018To investigate the dynamic resilient modulus of lime soil, and find out the law of resilient modulus decay under freeze-thaw cycle, adapting to the new design code and maintenance system of highway subgrade in China, a series of dynamic tests were carried out according to the standard laboratory test methods (JTG D30-2015).

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 ...

The resilient modulus ( M r ) is typically interpreted as the average of the last five secant slopes of the cyclic stress-axial resilient strain curve from repeated loading triaxial tests. It is not uncommon to then fit mathematical models to the secant

Current pavement design procedures recommend the resilient modulus of subgrade materials for pavement design and analysis. The objective of this paper is to develop two statistical models to predict the resilient modulus of subgrade cohesive soils from the dynamic cone penetration (DCP) test parameters and soil properties.

The matric suctions were measured by the filter paper method, and the parameters of soil-water characteristic curve were obtained. In order to investigate the effect of moisture content on cohesive subgrade soils dynamic resilient modulus, a series of dynamic-triaxial test were carried out.
