Resilient Modulus Variations with Water Content

2003
Resilient modulus (MR) variations with water content were carefully examined for three subgrade soils—lean clay, clayey sand, and clayey gravel. For each soil type, four MR tests were performed at the following water contents: 2 to 3% dry of optimum, at optimum; 2 to 3% wet of optimum; and at full backpressure saturation.

Predicting resilient modulus of fine-grained subgrade soils considering relative compaction and matric suction

International Journal on Road Materials and Pavement Design, 2019
The resilient modulus has been used to characterise the stress-strain non-linear behaviour of subgrade soils and is an important parameter for pavement design and analysis.

Resilient Modulus for Fine‐Grained Subgrade Soils

Journal of Geotechnical Engineering, 1994
A method has been developed for the estimation of resilient modulus of compacted fine-grained subgrade soils. The method takes into account the influence of soil physical state, stress state, and soil type. The effect of soil physical state is quantified by combinations of two equations relating resilient modulus to moisture content.

Effects of water content on resilient modulus of a granular material with high fines content

, 2020
The granular materials with high fines content are commonly adopted as the fill materials in the substructures of pavement and railway. The high-fraction fines may exist at the construction stage or accumulate gradually during the service life of ...
