Loading mode is an important but under-estimated factor for the dynamic modulus test of asphalt concrete. This article presents a comparative laboratory study of using uniaxial-compression, two-point bending and three-point bending to test dynamic modulus of 12.5 mm asphalt concrete (AC) with two asphalt materials. Dynamic moduli |E*| and phase angle φ between different tests were compared and analyzed in multiple ways. Results show that good correlations exist between |E*| and φ of different loading modes, but the values of |E*| and φ, as w...
