Anti-Skid Thin Layer on Asphalt Pavement of Super Long Downgrades
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.
