Metamaterial concrete, preparation method thereof and rigid-flexible composite pavement structure
The invention discloses metamaterial concrete, a preparation method thereof and a rigid-flexible composite pavement structure, and belongs to the technical field of road construction. The metamaterial concrete disclosed by the invention is provided with a Cartesian oval line hole, the Cartesian oval line hole is filled with a phase change material, under a two-dimensional Cartesian coordinate system, the expression of the Cartesian oval line is as follows: (x2 + y2) 2 + 2a2 (y2-x2) + a4-b4 =, in the formula, a is 3.76-7.51 mm; and b ranges from 4.19 mm to 8.39 mm. The metamaterial concrete disclosed by the invention has the performance of autonomously regulating and controlling the temperature and also has the characteristic of negative Poisson's ratio, and when the metamaterial concrete is applied to a rigid-flexible composite pavement structure, the compression resistance and the impact resistance of the pavement structure can be enhanced, the overall strength, the toughness and the crack resistance of the pavement can be improved, and finally, the design of a cool pavement is realized.
本发明公开了一种超材料混凝土及其制备方法、刚柔复合式路面结构，属于道路建设技术领域。本发明公开的超材料混凝土，具有卡西尼卵形线孔，所述卡西尼卵形线孔内填充有相变材料，在二维笛卡尔坐标系下，所述卡西尼卵形线的表达式为：(x2+y2)2+2a2(y2‑x2)+a4‑b4＝，式中，a为3.76‑7.51mm；b为4.19‑8.39mm。本发明的超材料混凝土具有自主温度调控的性能，同时也具有负泊松比特性，将其应用在刚柔复合式路面结构中，可以增强路面结构的抗压缩性能和抗冲击能力，提高路面的整体强度、韧性和抗裂性能，最终实现清凉路面设计。
