Research on the Rolling Process of SMA-13 Asphalt Surface Layer for Bridge Decks Based on Compaction and Skid Resistance Equilibrium Problems

In order to solve the equilibrium problem related compaction degree, structural integrity of skid resistance, and resistance asphalt wearing layer on a concrete bridge deck, influence rolling mode performance was analyzed according curve characteristics, image processing technology, laser method from mechanism temperature control equipment. The results showed that degree times an SMA-13 course deck could be characterized by logarithmic model, model parameters had clear physical significance. Compared with vibratory roller, oscillation roller achieve greater more stable mixture maintain better density, void ratio after 5 rolling. pavement wear characteristics were extracted digital method. increase in times, decreased gradually, rate surface texture increased significantly. multiscale evaluation antiskid structure gradually tended (1.2 mm) microscopic density proportion acute angle (<90°) peak profile times. rolled for 6 so as balance integrity, resistance.
