Bituminous pavement surfaces must meet special requirements for riding comfort, frictional characteristics, permeability, tire and pavement wear, segregation, raveling, appearance, light reflectance, and noise. The focus of this paper is on the progress the asphalt industry has made to date in addressing these special requirements and the challenges it faces in the future. Various technologies and methods are described, including the growing use of the Superpave system for material selection and design of asphalt mixtures. |
