| 摘要： | This document of 15 papers that explore the evolution of thermoplastic properties of asphalt mixtures with oxidation aging; calibration and validation of a comprehensive constitutive model for asphalt mixtures; mode-dependent fracture behavior of asphalt mixtures with semicircular bend test; a comparison of fatigue damage, healing, and endurance limits with beam and uniaxial fatigue tests; and a numerical–experimental approach to characterize fracture properties of asphalt mixtures at low temperatures.This TRR also analyzes an approach to estimate the rheological properties of asphalt binders; laboratory hot-mix asphalt performance tests; the laboratory conditioning procedures to simulate mixture property changes effectively in the field; American and European mix design approaches; and balanced asphalt mixture design through specification modification.Additionally, this TRR examines the effect of laboratory mixing and compaction temperatures on asphalt mixture volumetrics and dynamic modulus; the effect of long-term ambient storage of compacted asphalt mixtures on laboratory-measured dynamic modulus and flow numbers; development of a failure criterion for asphalt mixtures under different modes of fatigue loading; characterization of microdamage healing in asphalt concrete with a smeared continuum damage approach; and a multiscale model for asphalt mixtures subjected to cracking and viscoelastic deformation. |
