Study on Roadbed Soil Dynamic Resilient Modulus Test

Advanced Materials Research, 2013
This paper draws on the successful experience from domestic and abroad researches, testing repeatedly of powder subgrade with load triaxial tests, analyzing the relationship between the subgrade soil resilient modulus, deviatoric stress, water content and degree of compaction.

Experimental Study of Dynamic Resilient Modulus of Cohesive Soils in Henan

Advanced Materials Research, 2014
Subgrade 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

Automated Dynamic Cone Penetrometer for Subgrade Resilient Modulus Characterization

Transportation Research Record: Journal of the Transportation Research Board, 2002
Subgrade soil characterization, expressed as resilient modulus ( M R ), is crucial for pavement design. For a new design, M R is generally obtained by conducting repeated triaxial tests on reconstituted and undisturbed cylindrical specimens.

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 ...

An empirical predictive model for the dynamic resilient modulus based on the static resilient modulus and California bearing ratio of cement- and lime-stabilised subgrade soils

Road Materials and Pavement Design, 2020
This study uses two typical subgrade soil samples selected from a highway construction site in Jilin Province, China, to formulate an empirical predictive model for the dynamic resilient modulus (E...

Resilient Modulus Prediction of Subgrade Soil Using Dynamic Cone Penetrometer

2018
Stress-strain response of pavement structure is commonly presented with resilient modulus (Mr). Resilient behavior of subgrade soils is measured using expensive laboratory tests, that is somewhat time-consuming. Design engineers sometimes, uses overestimated backcalculated values from non-destructive test, which in turn lead to over-design of pavement.

Experimental Investigation on Dynamic Resilient Modulus of Lime Stabilized Clay Soil

2018
To 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).

Study on the dynamic compressive resilient modulus and frost resistance of semi-rigid base materials

Road Materials and Pavement Design, 2017
In 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 ...
