Attachment 4 Table 703-3.pdf

This document is a technical specifications table (Table 703-3) that establishes target value ranges for surface gradation of aggregate materials. The table specifies percent by mass passing requirements for designated sieves using AASHTO T 27 and T 11 testing standards across six grading designations: F, G, H, S, T, and U.

The table provides gradation specifications for eleven sieve sizes ranging from 1 1/2 inch down to No. 200, with each sieve size containing target value ranges for the applicable grading designations. For example, the 1 inch sieve requires 97-100 percent passing for Grade F, 100 percent for Grade G, 72-92 percent for Grade S, and 100 percent for Grade T. Smaller sieves such as No. 200 (10.0-16.0) and No. 40 (15-23 for Grade F) provide tighter gradation control for fine aggregate components. The footnotes indicate that values in parentheses represent allowable deviations from target values, with specific notation that if plasticity index exceeds zero, the television range for No. 200 sieve size is 8-12. This specification table would typically be referenced in construction contracts, material procurement standards, or quality assurance requirements for aggregate materials used in pavement, concrete, or other infrastructure applications.
