Osterberg load cell test results on base grouted bored piles in Bangladesh

The paper presents the results of an Osterberg load test program performed for the Paksey Bridge over the Padma (Ganges) River in western Bangladesh. The test program included the installation and testing of two 1.5-m diameter bored piles to depths of 65 m and 91 m. The paper discusses the design of the high capacity bored piles for a site susceptible to deep scour. The paper also discusses the installation of the test piles, and the application of base-grouting to improve end bearing resistance. Finally, the paper documents and evaluates the results of Osterberg load tests at the two test piles, including a comparison of pile capacity prior to and following base grouting.
