Component

In highway construction, rocks, asphalt, concrete and other materials are used. Electrical properties of these materials are related to pavement performance. Understanding electrical properties of rocks are essential in predicting pavements performance. Two automatic measurement systems were developed for measuring the electrical properties of rocks with different water and oil saturation levels. The systems cover a frequency band from 10 KHz to 1.1 GHz. The operating software of these systems was developed based on LabVIEW for equipment control, sample measurement and data processing. Easy-to-use software interfaces were also provided. By implementing these automatic measurement systems, the procedure for sample measurement and data processing are simplified and much more efficient. Dielectric property measurements on the samples of different materials with different structure and different moisture contents were performed to verify the measurement accuracy of the systems. The mortar samples with different moisture contents were measured; and the experimental data, which were not available in existing electrical property tables, are presented.
