| Abstract: | The article introduces the design process for KH-25 concrete mixture ratio and conducts a research test on various items of highway performance. The test result and the practices in Nanning -Liuzhou highway show that the content of coarse aggregate in KH-255 asphalt mixture is higher than that of the common coarse asphalt mixture. It belongs to the dense gradation skeletal compacting structure,which is free of segregation during construction. Thanks to its perfect compactness and durability and strong anti-track capacity,the mixture can be used in the middle and surface course of asphalt pavement. It has great application value for popularization. |
