Improving the skid resistance performance of asphalt pavement is an effective way to meet the requirements of safe driving on super long continuous downgrades. The anti-skid performance attenuation of SMA-16 was tested in laboratory. The results showed that SMA-16 could meet the requirement of anti-skid performance in early stage, but the anti-skid performance decreased rapidly on super long downgrades. The long-term anti-skid performance of anti-skid thin-layer had also been carried out in laboratory. We can come to conclusion that anti-skid thin paving layer can meet the requirements of anti-skid performance even in the end of design life. The anti-skid thin paving layer on super long downgrades was designed, which not only satisfied the durability of skid resistance performance but also reflected the demand of economics.
