Abstract:
Field sampling and testing is an integral portion of quality control for soil mixing and slurry trenching applications. In order for a sampling and testing program to be effective, it must be completed properly such that it provides an accurate representation of the installed product. There are many testing standards for sampling and testing soil mixed products, however, they still need to be properly identified and applied to provide representative results. Specifications for soil mixing and slurry trenching projects sometimes include improperly selected testing standards or sampling/testing requirements that are not adequately addressed in any current standards. The purpose of this paper is to identify testing and sampling standards commonly specified for soil-cement mixtures in the stated applications and discuss how the standards are or are not suitable for these applications. This Part 1 of a two-part paper will review and discuss common standards used in this application, the applicability of those methods for soil-cement mixtures created in the stated applications, and conclude with recommendations for modifications to the existing standards for use in this application.
