Abstract:
The protocol using the Veris 3150 for determination of sulfate-rich soils has been implemented to two full-scale projects in Dallas and Paris Districts. The determination of organic-rich soil was not implemented in this project due to the unavailability of proper equipment. Researchers collected electrical conductivity (EC) data from two Veris 3150 units equipped at both TxDOT and TTI, simultaneously. Soil samples were collected on the basis of the constructed EC color map. The data collected from these projects were analyzed to identify potential relationships between Veris EC measurements and sulfate contents for different types of soil. Statistical modeling results indicate that Veris EC is a linear function of the natural log of the sulfate content, directly if other soil parameters such as moisture content, organic matter content, and clay content remain constant. Higher EC of soil responds to higher sulfate content of soil. It is imperative that soil samples be collected.
