【摘要】：城市道路与一般公路存在着较大的差异，主要表现在：在公交车站牌处、排水检查井以及地下管道埋置处等地极易出现路面病害。因此在其施工中应加强其摊铺、碾压质量控制，以保证其良好的路用性能。随着城市道路交通量的增长，城市道路沥青面层的施工质量问题也日益凸显出来，，主要表现在：原材料的质量问题、沥青混合料的配合比设计问题、沥青混合料拌和、运输、摊铺以及碾压等质量控制问题。有必要加强对城市道路沥青路面施工质量的控制，并分析研究相关技术方案加以有效管理，提高城市道路沥青路面的质量。本论文首先介绍了洛阳市国道310至吉利区新建公路工程的概况，然后根据其沥青面层的结构类型，提出了各结构层的原材料与混合料的质量控制的指标；在沥青混合料配合比控制中，通过大量的试验分析研究，提出了优化配合比设计的一些措施；针对城市道路施工的特殊性，对沥青混合料的拌合厂的选址提出了建议；对沥青混合料的拌和提出了从拌和设备的选型与试验检测、拌和温度控制等方面来进行沥青混合料拌和质量控制；对运输过程，提出了沥青混合料的保温控制措施；对摊铺碾压过程，提出了应从摊铺与碾压机械的选择、摊铺温度与摊铺厚度的控制、城市特殊地段的人工摊铺工艺的选择、压路机的配备与碾压程序的选择、接缝处理等方面对其施工质量进行控制；最后，分析研究了沥青面层的压实度、弯沉、构造深度、渗水系数以及平整度等质量评定方法。通过本论文的研究可以得到的认识有：各阶段的质量控制是城市道路沥青面层的施工质量的保证，城市道路的特殊性环境决定了其施工质量控制方法的不同性以及各路用性能指标的偏重性。
[Abstract]:There is a great difference between urban roads and general highways, mainly in the bus stop sign, drainage inspection wells and underground pipeline buried in places prone to pavement diseases.Therefore, it is necessary to strengthen its spreading and rolling quality control in order to ensure its good road performance.With the increase of urban road traffic volume, the construction quality problems of asphalt surface layer of urban road have become increasingly prominent, mainly manifested in: the quality of raw materials, the mix ratio design of asphalt mixture, the mixing of asphalt mixture, the transportation of asphalt mixture,Paving and rolling and other quality control issues.It is necessary to strengthen the quality control of urban road asphalt pavement construction, and analyze and study the relevant technical schemes to effectively manage the quality of urban road asphalt pavement.This paper first introduces the general situation of the newly built highway project from 310 to Jili District of Luoyang City, then according to the structure type of asphalt surface layer, puts forward the quality control index of raw material and mixture of each structure layer.In the control of mixture ratio of asphalt mixture, through a lot of experimental analysis and research, some measures of optimizing mix proportion design are put forward, and suggestions on the location of mixing plant of asphalt mixture are put forward in view of the particularity of urban road construction.The quality control of asphalt mixture mixing is put forward from the aspects of mixing equipment selection and testing, mixing temperature control and so on, and the heat preservation control measures of asphalt mixture are put forward for the transportation process.The selection of paving and rolling machinery, the control of spreading temperature and spreading thickness, the selection of artificial paving process in special sections of the city, the installation of roller roller and the selection of rolling procedure are put forward.Finally, the quality evaluation methods of asphalt surface such as compactness, deflection, structural depth, seepage coefficient and smoothness are analyzed and studied.Through the research of this paper, we can get the following conclusions: the quality control of each stage is the guarantee of the construction quality of the asphalt surface of the city road.The special environment of urban roads determines the difference of construction quality control methods and the emphasis of performance indexes.
