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)

Page 12: MSCR RESULTS IN OKLAHOMA KENNETH RAY HOBSON, P.E AUGUST 25, 2011 SEAUPG WEBINAR.

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
