Nanotechnology Will Impact on Asphalt

This article reports on current and future trends driving the global asphalt market. Research is underway on using nanotechnology (the art of manipulating matter, atom by atom) to create asphalt that mends itself when damaged. A structural polymeric material with the ability to spontaneously heal cracks has already been developed by incorporating a microencapsulating healing agent and a catalytic chemical trigger within an epoxy matrix. Although this technology shows promise, it probably will not be ready for actual paving use in the near future. A trend that does show promise for more immediate application is the use of recycled waste materials in asphalt. Rubberized asphalt paving is predicted to grow in use due to its noise-dampening properties. Research is also being conducted on asphalt materials that will meet the demand for stronger and more durable road pavements.
