Highway users have an increased awareness of pavement quality. To help agencies and contractors meet the demand for high-quality pavements, NAPA's Asphalt Pavement magazine regularly provides articles that directly address issues such as mix type selection and statistical specifications.
PaveXpress is a free, Web-based tool for the structural design of flexible and rigid pavements using the AASHTO 93/98 Supplement Design Guide. It supports pavements of all traffic levels, and includes modules for designing asphalt overlays, materials costing, layered elastic analysis, and more.
