【摘要】：近年来由于我国高速公路建设的飞快发展和汽车数量持续大幅增加，高速公路沥青路面频繁出现早期破坏现象。分析主要原因与路面本身材料选择和施工关键工序的控制不当有关，因此，针对沥青路面材料质量选择和施工关键工序施工质量研究迫在眉睫。吉草高速是吉林省干线公路黑大公路（G202）的重要组成部分，主要承担辽宁、吉林、黑龙江三省的客货运输，该工程是吉林省“十一.五”规划的重点工程，受到社会各界的普通关注，工程质量的优劣是整个建设项目的核心。本次研究主要针对我国高速公路沥青混合料路面施工过程中普通出现的质量问题，以吉草高速建设项目为依托，对沥青路面的原材料的选择、沥青混合料的拌和运输、摊铺及碾压等施工工序以及路面平整度和压实度控制方法进行研究，提出沥青混合料施工过程中各关键工序的流程质量控制的要点。在进行大量调研和试验的基础上，，提出了吉草高速材料选择的具体标准，指导吉草高速路面材料的优选；在进行室内试验后，对沥青混合料目标配合比设计、生产配合比设计和生产配合比进行验证并对材料选用以及施工过程中容易发生的问题进行了深入研究，并提供了相应的解决方法。最后从沥青混合料施工时通常出现的离析、压实度不足或过度及平整度不足等现象作为切入点，分别对这三种问题进行了深入研究，提出了改善方法和措施。
[Abstract]:In recent years, due to the rapid development of highway construction in China and the sustained and substantial increase in the number of cars, The analysis of the main causes is related to the material selection of the pavement itself and the improper control of the key construction procedures. It is urgent to study the quality selection of asphalt pavement materials and the construction quality of key construction procedures. Jicao high speed is an important part of the main highway of Jilin Province, which mainly undertakes passenger and freight transportation in Liaoning, Jilin and Heilongjiang provinces. The project is one of the key projects in the "11th Five-Year Plan" of Jilin Province, which has received general attention from all walks of life. The quality of the project is the core of the whole construction project. This research mainly aims at the common quality problems in the construction process of asphalt mixture pavement of expressway in China, relying on the high speed construction project of Jicao, the selection of raw materials of asphalt pavement, the mixing and transportation of asphalt mixture. The construction procedures such as spreading and rolling, as well as the control methods of pavement smoothness and compactness are studied, and the key points of process quality control of each key process in the construction of asphalt mixture are put forward. On the basis of a large number of investigations and tests, the paper puts forward the specific criteria for selecting high speed materials of Jicao, instructs the selection of materials for high speed pavement of Jicao, and designs the mix ratio of asphalt mixture after indoor test. The design of the production mix ratio and the production mix ratio are verified, and the selection of materials and the problems easily occurring in the construction process are studied in depth, and the corresponding solutions are provided. Finally, starting from the phenomena of segregation, compaction deficiency, excessive compactness and unevenness, which usually occur in the construction of asphalt mixture, the paper makes a thorough study on these three problems, and puts forward the improvement methods and measures.
