Old cement concrete paving reconstruction method
The invention discloses an old cement concrete paving reconstruction method. The method comprises the following steps: a, cleaning up an original pavement; and b, mixing an artificial reinforced aggregate with an aggregate, paving a mixture on the original pavement, and paving an asphalt mixture, or mixing the artificial reinforced aggregate, the aggregate and the asphalt mixture, and paving the mixture on the old pavement. The artificial reinforced aggregate has a multi-stage space skeleton structure and is mutually embedded and extruded with the aggregate to form an interlocking structure. The specific aggregate and aggregate are adopted to form a mutually-embedded interlocking structure, with the bonding effect of asphalt, the strength of the formed pavement structure layer is higher, the artificial reinforced aggregate and the aggregate do not slip under the vehicle-mounted effect, high internal friction resistance can be formed after the artificial particles and the common aggregate are embedded and extruded, the aggregate cannot slip, the plastic flow trend cannot be generated under the action of external horizontal load, the interlocking effect is strong, and the stability and the deformation resistance of the asphalt mixture can be improved.
本发明公开了一种旧水泥混凝土加铺改造方法，包括以下步骤：a.将原路面清理干净；b.将人造增强骨料与集料混合后加铺于原路面上再摊铺沥青混合料；或者将人造增强骨料、集料和沥青混合料混合后摊铺于旧路面上；所述人造增强骨料具有多级空间骨架结构并与集料相互嵌挤形成嵌锁结构。加铺层采用特定的骨料与集料形成相互嵌挤的嵌锁型结构，再结合沥青的粘接作用，所形成的路面结构层强度更高，人造增强骨料和集料在车载作用下不但不会发生滑移，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。
