【摘要】：目前,我国高速公路处于快速发展时期,随着高速公路里程的增加和使用时间的延长,公路养护工程量也越来越大。养护工程一般分为针对性养护和预防性养护,针对性养护是指当路面出现破坏时,根据病害类型采取相应的措施,改善路面的使用性能。预防性养护是指在沥青路面性能尚处于良好状态时,实施微表处、超薄磨耗层、雾封、灌缝等技术措施对路面实施保护性养护,在不增加结构承载能力的前提下改善路面的功能状况,以阻止微小病害的发展,延缓严重的破坏。高聚物注浆技术是一种新兴的道路养护技术,可以快速、无损、经济的修复路面病害。本论文针对高速公路沥青路面的养护工程,以合徐高速公路南段、马巢高速公路沥青路面的高聚物注浆技术应用实施路段为依托,深入探讨了高聚物注浆技术在养护工程中的应用研究。本论文研究内容包括以下六个方面：路面病害及维修技术调研；高聚物注浆材料的性能试验：高聚物注浆技术布点方案及效果评价；注浆实施路段路况调查；工程应用效果调查分析；高聚物注浆道路结构的力学分析。本文研究成果包括高聚物注浆技术的长期效果；高聚物注浆技术的适用条件；注浆维修后沥青路面的检测标准。研究成果为高聚物注浆技术大规模应用提供了技术基础。
[Abstract]:At present, the highway in our country is in the period of rapid development, with the increase of highway mileage and the extension of service time, the amount of highway maintenance engineering is also increasing. Maintenance engineering is generally divided into targeted maintenance and preventive maintenance. Targeted maintenance refers to taking corresponding measures according to the type of disease to improve pavement performance when pavement is damaged. Preventive maintenance refers to the implementation of micro-surface, ultra-thin wear layer, fog seal, grouting and other technical measures to protect pavement when the performance of asphalt pavement is still in good condition. In order to prevent the development of minor diseases and delay the serious damage, the function condition of pavement is improved without increasing the bearing capacity of the structure. Polymer grouting technology is a new road maintenance technology, which can repair pavement diseases quickly, nondestructive and economically. Based on the maintenance engineering of asphalt pavement of expressway, this paper relies on the application and implementation of polymer grouting technology in the south section of Hefei-Xuzhou expressway and the asphalt pavement of Ma-Jiao Expressway. The application of polymer grouting technology in maintenance engineering is discussed in this paper. The research contents of this paper include the following six aspects: pavement disease and maintenance technology investigation; polymer grouting material performance test; polymer grouting technology placement scheme and effect evaluation; grouting implementation road condition investigation; Investigation and analysis of engineering application effect; mechanical analysis of polymer grouting road structure. The research results in this paper include the long-term effect of polymer grouting technology, the applicable conditions of polymer grouting technology, and the testing standard of asphalt pavement after grouting maintenance. The research results provide the technical basis for the large-scale application of polymer grouting technology.
