【摘要】：建筑垃圾的再生利用是建筑全寿命周期中的一个重要环节,是实现建筑领域资源节约和节能减排的关键环节,对建筑废弃物的再生利用的研究已然成为我国城市更新建设工作中的当务之急。市政道路工程中一般对集料的强度要求不高,且不涉及到安全问题,更重要的是道路工程中再生集料应用量巨大,废弃物再生集料的应用潜力非常大。因此,将建筑废弃物有效利用于市政道路工程可能是解决建筑垃圾围城、资源再利用的最快速、最简易和最有效的途径之一。本文就建筑废弃物再生骨料在市政道路工程中应用的关键技术开展了相关的研究和分析,主要得到以下研究成果:(1)建筑废弃物的再生过程中的关键工艺是将建筑废弃物材料的破碎与筛分进行有机的衔接,这个流程的衔接关键在于提高建筑废弃物材料的破碎效率。进行建筑废弃物预筛分不仅可以有效的去除建筑废弃物当中的粒径较小的颗粒,还可以去除建筑废弃物材料当中的水份,为提高建筑废弃物筛分效率打下良好的基础。(2)按建筑废弃物的组成情况以及技术指标检测结果,可将其用于市政道路的沥青路面面层、半刚性基层、垫层等部位。(3)建筑废弃物再生骨料可应用于排水基层,相关的检测结果表明其弯沉值等技术指标均在相关规范要求范围以内。(4)建筑废弃物再生骨料可应用于市政道路沥青路面中,室内试验及试验段取芯结果表明材料具有良好的路用性能。(5)在管理层面上对建筑废弃物处理的方式方法进行研究,以广州市为研究对象,提出了对于建筑废弃物在政府以及相关部门和企业层面上的处理问题,并提出来相关的意见和建议。
[Abstract]:The recycling and utilization of construction waste is an important link in the whole life cycle of the building, and it is the key link to realize the resource saving and energy saving and emission reduction in the construction field. The research on the recycling of construction waste has become an urgent task in the urban renewal and construction of our country. Generally speaking, the intensity of aggregate is not high in municipal road engineering, and it does not involve safety problems. More importantly, the application of recycled aggregate in road engineering is huge, and the application potential of waste recycled aggregate is very great. Therefore, the effective use of construction waste in municipal road engineering may be to solve the problem of building waste besieging. One of the fastest, easiest and most effective ways to reuse resources. This paper has carried out relevant research and analysis on the key technology of application of recycled aggregate of construction waste in municipal road engineering. The key process in the regeneration process of construction waste is the organic link between the crushing and screening of construction waste materials. The key to this process is to improve the crushing efficiency of construction waste materials. It can also remove water from construction waste materials and lay a good foundation for improving the screening efficiency of construction waste. (2) according to the composition of construction waste and the test results of technical indicators, it can be used in the asphalt pavement surface of municipal roads. Semi-rigid base, cushion, etc.) recycled aggregate from construction waste can be used in drainage base. The relevant test results show that its deflection value and other technical indexes are within the scope of relevant specifications. 4) the recycled aggregate of construction waste can be used in the asphalt pavement of municipal road. The results of indoor test and coring of test section show that the material has good road performance. (5) on the level of management, the methods and methods of disposal of construction waste are studied, and Guangzhou City is taken as the research object. The disposal of construction waste at the level of government and related departments and enterprises is put forward, and some suggestions and suggestions are put forward.
