HIGH-PERFORMANCE ASPHALT : THE NEW GENERATION OF PAVEMENT

This article presents a review of the newest technologies and techniques developed for hot mix asphalt over the past 15 years. Stone-skeleton mixes and polymers make them rut-resistant and more elastic. New pavement profilers and milling machines can remove portions of the surface so precisely that an absolutely flat surface can be created, allowing optimal compaction. Machines capable of continuous removal of old pavement and placement of new asphalt permit more consistent mixes and uniform base layers. Open-graded mixes use polymers and fibers for quieter, better draining surfaces. Listed are seven advantages to asphalt over concrete, including durability, smoothness, use of recycled materials, safety, noise, speed of construction, and ability to support heavy loads.
