Evaluation and Guidance Development for Post-Grouted Drilled Shafts for Highways

This online engineering PDH interactive presentation provides a brief guidance for the design and construction of post-grouted drilled shafts through cost-effective and appropriate use of post-grouting techniques.

Although post-grouting of drilled shafts has been performed for nearly four decades in Europe, there has been limited application of post-grouting in the United States. Post-grouting is typically accomplished using a grout delivery system that is incorporated into a drilled shaft during construction. However, concerns remain regarding the reliance on improved performance for post-grouted drilled shafts.

This presentation summarizes the current state of practice for post-grouting of drilled shafts in the U.S., documents the analyses and evaluations performed to evaluate alternative improvement mechanisms for PGDS, and describes the findings and recommendations developed based on the work performed. The presentation concludes with recommendations for future work needed to improve post-grouting practice for transportation infrastructure.

This 4 PDH online interactive presentation is applicable to civil engineers, construction and transportation planners, designers, and other technical professionals who are involved in the grout distribution services.
