About this file
This is a technical specifications document for surface coarse aggregate used in the NFSR 116 Surfacing/Stabilization contract work. The document provides detailed testing requirements and target gradation values that aggregate materials must meet.
The aggregate specifications establish performance requirements across multiple properties including liquid limit (35 maximum per AASHTO T-89), plastic limit (2 to 9 or less than 2 depending on No. 200 sieve passing percentage per AASHTO T-90), and plasticity index (less than 4 or 4 to 12 depending on No. 200 passing percentage). Additional durability and strength requirements include Los Angeles Abrasion maximum of 40% (AASHTO T-96), sodium sulfate soundness maximum of 12% over 5 cycles (AASTHO T-104), durability index minimums of 35 for both coarse and fine aggregate (AASHTO T-210), and fractured faces minimum of 75% (ASTM D 5821). The document provides target gradation ranges across six designations (F, G, H, S, T, U) for sieve sizes ranging from 1-1/2 inches down to No. 200, with allowable deviations from target values specified in parentheses. Special provisions apply when the plasticity index exceeds 0, adjusting the No. 200 sieve size target value range to 6-12 with a ±4 allowable deviation.
