This article discusses the importance of improving the durability of pavement concrete. In order to ensure the life of pavement design to be achieved, high-performance pavement concrete should be used. On the basis of the experimental study, the criteria for dividing the strength grade of high performance pavement concrete are proposed. The calculated flexural strengths are as follows: Grade 1 - 5 0 ~ 6 0MPa, Grade 2 - 6 5 ~ 7 5MPa, Grade 3 - 8 0 ~ 10 0MPa. Proposed the mix, respectively, to provide the durability of the measured results. The practical application is introduced, and the benefits of the application are described: raising the bearing capacity of the pavement, prolonging the service life of the pavement and reducing the construction cost.
