Materials
Use concrete with a minimum
of 3.6 ksi and Grade 60 reinforcing steel. Higher concrete strengths may be required in special cases. In highly congested bent caps due to reinforcement spacing, limit aggregate size of the concrete mix to a size that meets the minimum required reinforcement spacing in Article 5.10.3.1 based on the spacing provided.
