  • Systems, apparatuses and methods for assessing soil heave
    Patent number: 9822504
    Abstract: A method of assessing soil heave includes providing a plurality of determined values of a shear modulus of soil, the determined values being values of the shear modulus of the soil at different times; and determining a change over time in the shear modulus of the soil, based on the plurality of determined values of the shear modulus of the soil. The soil may have been treated by adding a stabilizer to the soil. The soil may be hydrated. A system for assessing soil heave includes a bender element disposed in soil, for determining a change over time of a shear modulus of the soil, and a time domain reflectometer probe disposed in the soil, for determining a change over time of moisture content of the soil. The determined change over time of the shear modulus and the determined change over time of the moisture content are used to assess heaving of the soil.
