Embodiment Construction

[0055] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.

[0056] The embodiments to be described here present the complex techniques and designs necessary to combine electrogeophysical techniques into a single instrument for testing soil or aggregate mineral materials and bitumen. The significant difference in these porous materials necessitates two electrical approaches with very different sensitivities in signal generation and measurement. Various embodiments may provide a single instrument for testing the physical properties of density and water content of both compacted aggregate mineral material and compacted bitumen.

Abstract

Test apparatus for testing porous material such as used in roadway base or building foundations may be deployed in the field at various test sites. The test apparatus includes electrodes that contactthe porous material under test and a sensor unit that supplies electromagnetic signals to the porous material. Response signals reveal electrical parameters such as complex impedance which can be equated to material properties such as density and moisture content. Reference may be made to empirical correlations made in laboratory tests using the same test apparatus to enable the effects of the test apparatus on the measurement to be accounted for. The electrodes may include flexible coplanar electrodes that reduce air gaps when in contact with the porous material.
