Study on Construction Technology of SMA Modifi ed Asphalt Pavement

With the rapid development of society and economy, road traffic volume is increasing day by day, which puts forward higher requirements on the bearing capacity of road pavement, and the current construction requirements of traditional asphalt materials are no longer available. As a kind of asphalt material with good road performance, SMA modifi ed asphalt concrete pavement is widely used in modern high-grade highway construction. Based on specifi c cases, this paper analyzes and discusses the construction technology and quality control of SMA modifi ed asphalt pavement, in order to provide a reference for the application of SMA modifi ed asphalt.
