State-of-the-Art Review of the Applications of Nanotechnology in Pavement Materials

摘要

Nanotechnology is the understanding and control of matter at the nanoscale of dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications. The use of nanotechnology in pavement materials is an area that shows great promise and the potential to change commonly used materials. The overall objective of this paper is to present a state-of-the-art literature review of nanoscience based principles to improve the performance of transportation construction materials. The article is organized into six sections, namely: applications of nanotechnology in concrete pavements, application of nanotechnology in asphalt pavements, application of nanotechno-logy in soils, cost-benefit, challenges, and trends to the future. It is observed from this review that nanoscience can help improve the performance of transportation construction materials and this may eventually lead to the extension of their life cycle.
