This issue contains 13 papers on the subject of bituminous materials and mixtures. Specific topics discussed include the following: permanent deformation of asphalt mixtures; fatigue crack propagation model of asphalt concrete; predictions of dynamic modulus of asphalt concrete mixtures; prediction of mechanical behavior of asphalt mixtures; a new test procedure for evaluating cracking resistance in bituminous mixtures; effect of thermal stresses on pavement performance under mild climate conditions; fracture energy of asphalt mixtures; the flow number simple performance test; a flow number predictive model; predictive models for populating dynamic moduli of long-term pavement performance sections; stiffening mechanisms of asphalt-aggregate mixtures; rutting resistance of laboratory-prepared and field-compacted asphalt mixtures; and the estimate of fatigue shift factors between laboratory tests and field performance.
