【摘要】：我国在过去的几十年,高速公路迅速发展,与此同时,城市道路数量也在快速的增长,但也产生了不少问题,路面普遍存在着早期损坏和耐久性差等问题。道路在修筑过程中,由于材料、结/构以及施工工艺都会不可避免的产生/变/异/性,直接影响到道路使用过程中/的舒适性和安全性,造成比如车辙、拥包、沉陷等一系列早期病害,降低路面的服役寿命。本文主要通过对城镇道路在施工过程中质量的动态管理与控制,探索在城镇道路各施工生产环节的关键因素,找寻对这些因素的动态管理与过程的控制方法,尽量保证施工与设计的一致性,提高施工质量的稳定性,减小施工过程中的变异性,保证路面的使用质量,延长道路的使用寿命。本文依托青岛市重庆路道路工程,依据在施工过程的特点提出影响路基路面的主控指标,并对材料、结构、施工工艺进行符合型检验,确定影响沥青路面施工质量的关键因素。建立现场路基路面各层回弹模量与其主控指标的关系,以达到通过控制现场主控指标来使得施工回弹模量符合设计回弹模量的要求,提高现场施工质量,满足设计要求。
[Abstract]:In the past few decades, the expressway has developed rapidly in our country. At the same time, the number of urban roads is also increasing rapidly, but there are also many problems, such as early damage and poor durability. As materials, structures and construction techniques will inevitably produce / change / differ / change, which directly affects the comfort and safety in the course of road use, resulting in a series of early diseases such as rutting, packing, subsidence and so on. Through dynamic management and control of the quality of urban roads during construction, this paper explores the key factors in the construction and production of urban roads. In order to ensure the consistency of construction and design, improve the stability of construction quality, reduce the variability in construction process and ensure the quality of pavement, the dynamic management and process control of these factors can be found. Based on the characteristics of the construction process, the main control indexes affecting the roadbed and pavement are put forward in this paper, and the materials, structures and construction techniques are checked according to the characteristics of the construction process. The key factors affecting the construction quality of asphalt pavement are determined. The relationship between the springback modulus of each layer of roadbed and pavement on site and its main control index is established, so that the modulus of springback meets the requirements of design modulus of springback through controlling the main control index of asphalt pavement. Improve the construction quality and meet the design requirements.
