Use of nanotechnology in concrete pavements

Abstract Concrete pavements are commonly used infrastructural assets that require various types of materials. There are many technologies and materials to improve the engineering properties and sustainability of concrete pavements. One such technology that opens new horizons in civil engineering involves nanomaterials. Use of nanomaterials increases structural strength and durability against aggressive chemical compounds and elements that extend the effective service life of the concrete pavement. Furthermore, nanomaterials can enhance environmental stewardships of concrete pavements through the reduction of demand for raw materials for maintenance and rehabilitation. Therefore, nanomaterials play a pivotal role in the development of high-strength and low-energy concrete pavements, especially for heavy-duty applications. In this chapter, various types of nanomaterials and pertinent performance mechanisms on the structural response of concrete pavements are discussed. In addition, the results of laboratory and field studies on the environmental burdens of nano-concrete pavements are analyzed in detail. In conclusion, the challenges of nano-concrete pavements as resilient infrastructure are discussed.
