TRENDS1. Most PG 70-28’s and All PG 76-28’s

Grade as PG 64-28 E2. Jnr3.2 > 4.0 kPa-1 (4 of 12 PG 64-22)

• Not PG 64-22 S3. Jnr3.2 < 0.0 kPa-1 (8 of 12 PG 76-28)

Page 12: MSCR  Results in Oklahoma

CONCLUSIONS1. 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
