旧路面碎石化施工工法
旧路面碎石化施工工法
摘要:文章主要阐述了旧路面碎石化施工工艺原理及特点,从而针对旧路面碎石化施工工艺流程及相关的操作要点进行了分析,提出了施工过程中的质量控制及安全措施,并结合工程的应用实践,着重论述了其施工工法在旧路面施工中应用价值,大量的工程实践证明,碎石化施工工法不仅有效消除桥梁板底空洞和板内应力,减少反射裂缝,延长大修工程使用寿命,而且其噪音小,扬尘少,碎石化路面后直接加铺结构层,避免旧面板挖弃,节省了经济成本,减少了污染环境。

Abstract: the paper mainly expounds the old pavement broken petrochemical construction technology principle and characteristics, so as to break old pavement petrochemical construction procedure and related key operation, this paper analyzed the construction process of quality control and safety measures, and combined with the application of engineering practice, this paper discusses the construction technique in the old pavement construction in the application value, a large number of engineering practice shows, broken petrochemical construction methods not only effectively eliminate bridge bottom hole and plate stress, reduce reflection crack, prolong the service life of repair engineering, and the noise is small, less dust, broken petrochemical pavement directly after that add a store structure layer, avoid old panel dig abandon, save the economic costs, reduce the pollution of the environment.
Keywords: old pavement, broken petrochemical, construction technique, technique principle, key operation

改革开放以来,我国的公路建设事业得到了蓬勃的发展。特别是九十年代我国大规模基础建设的迅速展开,水泥砼路面公路得到飞速发展。由于使用年限到期、交通量和载重量急速增长,越来越多的水泥砼路面将进入大修阶段。
旧路面碎石化施工是以多锤头破碎机和Z型压路机为主要施工机械,通过碎石化旧路面板来达到处治效果的施工方法。该施工方法能有效地解决旧板板底脱空,消除板内应力,同时又保留一定的旧面板强度,为加铺结构层提供有力支撑。
