Ultra-large-particle-size hydraulic asphalt concrete impermeable material
The invention discloses an ultra-large-particle-size hydraulic asphalt concrete impermeable material and a rock-fill dam built through the material. The mineral aggregate gradation index of the impermeable material is 0.38, the largest aggregate size of aggregate is 31.5 mm, and the asphalt-aggregate ratio of asphalt content of the impermeable material is 6.5%. The material meets standard requirements of the roller compacted asphalt concrete core wall technology. When the ultra-large-particle-size hydraulic asphalt concrete impermeable material is used in actual projects, the pressure bearing capacity of a hot asphalt mixture can be greatly improved. Roller compaction construction equipment of a roller compacted asphalt concrete core wall and transition materials on the two sides is unified. Equipment cost in the roller compacted asphalt concrete core wall construction process is reduced, and workloads for maintenance and management are reduced. Meanwhile, construction cost of a roller compacted asphalt concrete core wall project is reduced. By means of the material, the construction pave thickness of the roller compacted asphalt concrete core wall is increased, daily construction intensity of the roller compacted asphalt concrete core wall can be improved to a large extent, and technological supports are provided for ensuring the construction process of the roller compacted asphalt concrete core wall project.
