Federal Highway AdministrationFederal Highway AdministrationThis report focuses on the engineering practice of chemical grouting, summarizing the findings of a study to improve design and control techniques for chemical grouting in soils. Improved methods for the planning, control and evaluation of chemical grouting are now available. These include a better understanding of injection behavior, grouted materials, electronic process monitoring for better field performance and improved geophysical testing methods to measure grouting quality. This report is the fourth in a four-volume series. The others in the series are: FHWA/RD-82/036 Construction Control FHWA/RD-82/037 Materials Description Concepts FHWA/RD-82/038 Engineering Practic
