Experimental study on the performance of the double-layer SMA mixture in the south approach bridge of Sutong Bridge;

Design of suiting SMA mixture by revolving pressure apparatus;

The application of stabilizer in SMA mixture;

Combined with the Three-ring Road Project in Xi an,the application of SMA asphalt mixture of Bahe Super Bridge pavement was put forward.

Based on the construction technology and characteristics of SMA asphalt mixture, the material sel- ection, main construction equipments, gradation of mixture are introduced.

3% Methyl Cellulose content in the SMA mixture is determined by the experience and lack of the lab data,and the article gives the laboratory research method for determining the Methyl Cellulose content in the SMA mixture,which is based on the mixture performance tests.

With the design of stone matrix asphalt SMA-5 and the performance test of the designed SMA-5 asphalt mixture,it shows that current design method of SMA asphalt mixture can also be applied to the SMA-5,and the SMA-5 asphalt mixture has good pavement performance and superficial performance.
