Title:
METHOD OF TESTING SOIL OF ENGINEERING WORK MATERIAL
Document Type and Number:
Japanese Patent JP2010054419
Kind Code:
A
Abstract:

To provide a method of testing a soil of an engineering work material, capable of accurately predicting trafficability of the engineering work material in a rainy weather, used as an embankment for a roadbed, a subgrade, or the like.

The method of testing the soil of the engineering work material prepares a sample 1 of the engineering work material by compacting the engineering work material having a moisture content of an optimum moisture content or higher and of the optimum moisture content of 3 mass% higher or lower, brings a testing machine wheel 6 set to a contact pressure equivalent to a tire contact pressure of a construction machine into contact with the surface of the sample, moves the wheel repeatedly in a contact state, measures an amount of deformation of the sample when the testing machine wheel is repeatedly moved in the contact state, and determines the trafficability of the engineering work material from measured results of the amount of deformation.
