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 ...

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.

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 ...

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 Prediction Model of Dynamic Resilient Modulus of Cohesive Subgrade Soils Considering Moisture Variation

Applied Mechanics and Materials, 2014
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.

Possible estimation of resilient modulus of fine-grained soils using a dynamic lightweight cone penetrometer

International Journal of Pavement Engineering, 2015
AbstractResilient modulus is an important parameter to characterise the resilient behaviour of pavement materials. Resilient modulus can be determined in the laboratory from repeated load triaxial test and is defined as the ratio of deviator stress to recoverable strain. Inherently, it is a challenge to perform repeated load triaxial tests as a routine

Nonlinear Interpretation of Resilient Modulus Parameters Considering Incremental Static and Dynamic Loading

Transportation Research Record: Journal of the Transportation Research Board
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
