Asphalt pavement structure
The invention discloses an asphalt pavement structure. The structure comprises a pavement layer which is located on a base layer and formed by paving aggregate, artificial reinforced aggregate and an asphalt mixture, the artificial reinforced aggregate is a plurality of artificial particles with insertion strips, the insertion strips of the artificial particles are distributed in space to form a multi-stage space framework structure, and the aggregate is embedded and extruded between the insertion strips of the artificial reinforced aggregate. The artificial reinforced aggregate with the multi-stage space skeleton structure and the aggregate are mixed with the asphalt mixture for paving, the artificial reinforced aggregate and the aggregate are interlocked, lapped and engaged to form an interlocking structure, and with the bonding effect of the asphalt, the formed pavement structure layer is higher in strength. After the artificial particles and common aggregate are extruded in an embedded manner, relatively high internal friction resistance can be formed, so that the aggregate cannot slip, a plastic flowing trend cannot be generated under the action of an external horizontal load, the interlocking effect is strong, and the stability and deformation resistance of the asphalt mixture can be improved.
本发明公开了一种沥青路面结构，包括位于基层上的由集料、人造增强骨料和沥青混合料铺装成型的路面层，集料所述人造增强骨料为若干具有嵌条的人造颗粒，所述人造颗粒的嵌条沿空间分布呈多级空间骨架结构，所述集料嵌挤于人造增强骨料的嵌条之间；采用具有多级空间骨架结构的人造增强骨料和集料与沥青混合料混合进行铺装，人造增强骨料和集料，相互锁结、搭接，彼此咬合形成嵌锁结构，再结合沥青的粘接作用，所形成的路面结构层强度更高，人造颗粒与普通集料嵌挤后能形成较高的内摩阻力，使集料不会产生滑移，在外界水平荷载作用下不会产生塑性流动趋势，嵌锁作用强，可提高沥青混合料的稳定性和抗变形能力。
