Asphalt construction: A window to the future

More performance-based specifications and design-build projects will allow for greater freedom in hot mix design and construction methods. Contractors will complete large milling and resurfacing projects in record times. There will be more knowledge-based systems for delivering mix to projects, and pavers will become more automated and operator friendly. Global Positioning Systems and intelligent compaction systems will enable asphalt compactors to measure density on the go, and then send the information to an analysis center which will return information telling the roller where more compaction is needed. Warm mix asphalt will extend the paving season on both ends. The use of material transfer vehicles to remix and move asphalt from trucks to the paver will increase and, as a result, smoothness and quality control will improve. This article discusses these and other changes expected to occur in the future of asphalt construction. Specific topics covered include construction innovations, tracking and communications, intelligent paving, more uniform mix, and intelligent compaction.
