TRENDS
1. Most PG 70-28’s and All PG 76-28’s Grade as PG 64-28 E
2. Jnr3.2 > 4.0 kPa-1 (4 of 12 PG 64-22)
• Not PG 64-22 S
3. Jnr3.2 < 0.0 kPa-1 (8 of 12 PG 76-28)
CONCLUSIONS
1. R3.2 Limit Needed for: PG 70-28 and PG 76-28 - (60 Min. and 80 Min.?)
2. Other PG Grade Data Needed for R3.2 Limits
3. Do Not Round Computations Except for Limit Comparisons
