NCHRP1-37A yielded better E* values compared to NCHRP 1-40D model at all binder characterization input levels.
- •
NCHRP1-37A E* model with Level 3 binder characterization produced the most accurate and the least biased estimates.
- •
Because of the hot desert climate in KSA, care should be taken when using such models for E* predictions.
