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 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

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...

Comparing Resilient Modulus and Dynamic Modulus of Hot-Mix Asphalt as Material Properties for Flexible Pavement Design

Transportation Research Record: Journal of the Transportation Research Board, 2006
With the current trend toward developing mechanistic flexible pavement design and the need for more reliable design procedures, accurate characterization of hot-mix asphalt (HMA) properties is needed. Resilient and dynamic modulus tests were performed at five temperatures on two typical mixes used in the Commonwealth of Virginia to compare the test ...

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 ...

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.

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.
