Modulus of Subgrade reaction Which one to use

Modulus of Subgrade Reaction Which One Should be Used? By Wayne W. Walker, P.E.,F.ACI and Jerry A. Holland, P.E., F.ACI The modulus of subgrade reaction is an often misunderstood and misused concept for the thickness design of slabs-on-ground. Terzaghi in 1955 (Ref. 1, P. 300) attributed this confusion to the initial work by Hayashi in

Crushed Stone an overview ScienceDirect Topics

Crushed stone can generally substitute for sand and gravel, and vice versa. There are only a few naturally occurring materials that have the properties necessary to make an in-kind replacement for aggregate. The EN 13286-43 standard [30] provides guidelines in which the elastic modulus in compression is calculated using a force equal to 30%

Coarse Aggregate Properties

Crushed rock creates a much better bond between the paste and the aggregate than a gravel does. However, the aggregate-mortar bond may be more important in flexure tests than in compression tests. The mineral makeup of the aggregate also influences the modulus of elasticity of concrete.
