Cast asphalt waste tyre rubber powder concrete mixture and preparation method therefor
The invention relates to the road and bridge construction and maintenance technology field, and especially relates to a cast asphalt waste tyre rubber powder concrete mixture used for bridge deck pavement and a preparation method therefor. The mixture is prepared from aggregates, waste tyre rubber powder and asphalt at a mass ratio of 100:1-4:6-9. In a cast asphalt waste tyre rubber powder concrete bridge deck pavement layer, a cementation material is waste tyre rubber powder rubber asphalt, large elasticity and elastic recovery capability are achieved, the anti-deformation capability and anti-fatigue cracking performance of the pavement layer can be improved, and the mixing temperature is lowered by 50 DEG C at average. The beneficial effects are that energy saving and emission reduction can be achieved; raw material heating time is shortened and the production efficiency is raised; the construction temperature is far lower than a flash point, and safety is ensured; the aging degree of asphalt during the construction process is lowered.
