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.

Experimental Study of Dynamic Resilient Modulus of Cohesive Soils in Henan
Advanced Materials Research, 2014Subgrade soil is very important materials to support highways. Resilient modulus (MR) has been used for characterizing stress-strain behavior of base or subbase subjected to repeated traffic loadings. Several methods to estimate the resilient modulus were suggested in the past years. The main objective of this study was to test the resilient modulus in

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 ...

Study on the dynamic compressive resilient modulus and frost resistance of semi-rigid base materials
Road Materials and Pavement Design, 2017In the cold region, semi-rigid base materials are repeatedly subjected to the combined effect of freeze-thaw cycles and vehicle loading, and the supporting capacity and durability of the semi-rigid base structure degenerates generally. The dynamic compressive resilient modulus of semi-rigid base materials with three different cement contents after ...

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).
