Abstract
The road performance of SMA mixture is highly sensitive to the change of asphalt mixture ratio.When determining the laboratory mixture ratio,the indicators should be determined more strictly in order to get a better mixture ratio after the construction mixture ratio is veri-fied and adjusted.Based on the example of determining the proportion of SMA asphalt mixture,this paper mainly discusses the process of how to determine the target proportion of SMA-13 rubber asphalt mixture by mix design,confirm the proportion in practical application and finally establish a suitable pavement construction scheme,and deeply explores the relationship between the proportion of each component in asphalt mixture and the pavement serviceability as a reference for future highway construction.关键词
