【摘要】：在我国沥青路面施工过程中,对沥青路面施工的关键技术指标控制不当以及原材料等要素控制不合格,是导致路面在使用期当中出现早期破坏的重要原因。本文研究沥青路面施工质量控制从四方面入手：结构设计,混合料配合比,桥面防水层配合比,施工质量。(1)根据设计文件中所给的设计指标,设计要求和设计资料,结合路面设计规范,完成路面结构设计分析,并且在一定程度上对不同结构材料和交通量组成得到的路面面层进行对比优化。(2)研究Superpave路面设计方法的特点,分析所选用材料对道路施工过程中质量控制的影响以及与沥青路面不同早期破坏类型之间的联系。通过对体积设计分析,结合实际工程中交通量预测和重载交通比例等因素,论证路面各层所选用材料的合理性。(3)针对工程实地高架桥面铺装施工过程中防水粘结层出现的质量问题,分析现有规范提出的指标如碎石撒铺面积,沥青油喷洒量等的合理性,提出碎石粒径选取的合理范围和沥青撒铺量的控制指标,给桥面防水层施工中配合比控制提供相应的建议。(4)运用数理统计方法,基于施工关键指标建立沥青路面施工质量控制体系,并通过对施工关键指标之间的重要性关系进行互相对比,得出主要指标之间的相互关系以及进行相应质量控制时的注意点与对策。本文致力于改善当前沥青路面施工质量控制状况,提高沥青路面的施工质量和管理水平,延长路面使用寿命。
[Abstract]:In the process of asphalt pavement construction in our country, improper control of key technical indexes and unqualified control of raw materials are the important reasons leading to the early destruction of asphalt pavement in service life. In this paper, the construction quality control of asphalt pavement is studied from four aspects: structure design, mixture ratio of mixture, mixture ratio of bridge deck waterproof layer, construction quality. (1) according to the design index, design requirements and design data given in the design document, Combined with the pavement design specification, the pavement structure design analysis is completed, and the pavement surface layer which is made up of different structure materials and traffic volume is compared and optimized to a certain extent. (2) the characteristics of Superpave pavement design method are studied. This paper analyzes the influence of the selected materials on the quality control in the course of road construction and the relationship between the selected materials and the different early failure types of asphalt pavement. Through the analysis of volume design, combined with the actual engineering traffic volume prediction and heavy load traffic ratio and other factors, The rationality of the materials selected for each layer of pavement is demonstrated. (3) aiming at the quality problems of waterproof and adhesive layer in the course of pavement construction of viaduct, the rationality of the indexes proposed in the existing codes, such as the area of gravel spread, the amount of asphalt oil sprayed, etc., is analyzed. The reasonable range of gravel particle size selection and the control index of asphalt spreading quantity are put forward, and the corresponding suggestions are provided for the mix ratio control in the construction of waterproof layer of bridge deck. (4) the mathematical statistics method is used. The construction quality control system of asphalt pavement is established based on the key construction indexes, and the importance relations among the key construction indexes are compared with each other. The relationship between the main indicators and the corresponding quality control points and countermeasures are obtained. This paper is devoted to improving the quality control of asphalt pavement construction, improving the construction quality and management level of asphalt pavement, and prolonging the pavement service life.
