Abstract:

The objective of this report is to provide recommendation for the cost-effective design and construction of post-grouted drilled shafts (PGDS) in appropriate transportation applications. The work included review of available technical literature; consultation with those currently involved with post-grouting, collection, and interpretation of results from full-scale load tests on post-grouted and conventional drilled shafts; investigation and evaluation of load transfer and improvement mechanisms for PGDS using numerical models, conduct of field load tests intended to evaluate improvement due to pre-mobilization alone; and development of recommendations for design and construction of PGDS based on the collective work. This report 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 report concludes with recommendations for future work needed to improve post-grouting practice for transportation infrastructure.
