As previously required for No. 2 Stone, NYSDOT now requires No. 1 Stone to be tested for Freezing and Thawing (NY 703-08 P,G) and 10-Cycle Magnesium Sulfate Soundness (NY 703-07 P,G). Additional qualification requirements are presented in NYSDOT Standard Specification, Section 703-02 “Coarse Aggregate” and Table 703-2 “Coarse Aggregate Physical Requirements”.

Additional Physical Tests Required by Section 703-02 and ASTM C33
• NY 703-11 P,G/ASTM C131: Los Angeles Abrasion
• NY 703-10 P,G: Minimum Unit Weight
• ASTM D4791: Flat Particles, Elongated Particles, or Flat and Elongated Particles
• ASTM D5821: Crushed Particles
• Table 703-3: Deleterious Materials
