Preparation method of prefabricated pouring type asphalt repairing material
The invention discloses a preparation method of a prefabricated pouring type asphalt repairing material. The method comprises the following steps: preparing an oil-rich pouring type asphalt mixture, prefabricating a standard test block on a backfield, demolding and storing at normal temperature, heating and remelting by microwaves on site, coating with a thermoplastic resin waterproof bonding layer, backfilling and repairing an original paving pit slot, hot-melting and splicing joints, spreading a thermal radiation-anti-aging nano-composite material, pressing in high-strength gravels and the like. According to the method, a pouring type asphalt mixing backfield prefabrication-field heating remelting technology is adopted, and high bonding strength, excellent water stability and fatigue cracking resistance are achieved, so that the problems that the extremely-high temperature of the surface of a steel bridge deck pavement reaches 70 DEG C or above, and ruts and displacement occur shorttime after operation are solved; and on-site rapid maintenance and rapid traffic opening are achieved, large-scale mixing construction equipment is not needed, and the pavement maintenance convenienceunder domestic large traffic flow is greatly improved.
本发明公开了一种预制浇注式沥青修补材料制备方法，包括富油型浇注式沥青混合料制备、后场预制成型标准试块、常温脱模存储、现场微波加热重熔、热塑性树脂防水粘结层涂布、原铺装坑槽回填修补和接缝热熔拼接、撒布热辐射‑抗老化纳米复合材料、以及压入高强碎石等环节。本发明技术采用浇注式沥青混合后场预制——现场加热重熔技术，具有较高的粘结强度、较优的水稳性能和抗疲劳开裂性能，从而解决钢桥面铺装表面极端高温甚至达到70℃以上，运营不久即出现车辙、推移的问题；实现现场快速养护、快速开放交通，且无需大型拌合施工设备，大幅提高国内大交通流下的路面铺装养护便捷性。
