Abstract: With the continuous development of the transportation industry, the requirements for highway quality are getting higher and higher. In order to improve the service life and performance of highways, technicians have made a lot of efforts in the research and development of construction materials. SBS modified asphalt concrete is a new type of construction material newly developed in recent years. Through a good mix ratio design and optimized construction technology, a better construction effect can be obtained, thereby making the pavement durability and high temperature stability The performance has been greatly improved, and it can also slow down the speed of road aging. Based on this, this article mainly discusses the construction technology and treatment technology of SBS modified asphalt concrete in municipal engineering for reference.
