Abstract: Highlights: [•] 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. [Copyright &y& Elsevier]
