【摘要】：泡沫沥青冷再生技术作为一项新型的路面再生技术,在节能环保的同时,降低了工程造价,可以说是一项实用性及适用性均较强的工程技术,也极为适用于我国目前面临的的数量巨大的公路大中修养护压力的现状。本文通过结合嘉兴地区泡沫沥青混合料的材料特性及气候条件进行相关试验研究,同时总结本地区的工程应用经验,力求摸索出一套适用于嘉兴地区的、可操作的泡沫沥青冷再生配比设计工艺及相关参数,为这项技术在嘉兴地区下一步的推广应用提供参考。针对沥青发泡特性,对嘉兴地区两种常用沥青进行了多组发泡比对试验,研究分析了沥青品种、发泡用水量等因素与沥青发泡效果的关系。选取嘉兴地区有代表性的泡沫沥青冷再生工程取样的铣刨料数据,总结该地区老沥青路面的使用特点及再生材料特性,为下一步配比设计提供参考。结合嘉兴地区工程应用的实际经验,对泡沫沥青冷再生混合料常用的设计方法进行了部分优化,特别对集料级配、沥青用量、拌合用水量等进行了调整。依托G320国道嘉兴段的实际施工工程,对泡沫沥青厂拌冷再生的路面结构方案制定、施工配合比设计、施工组织及质量控制,工程后期的试验检测等工程进行了总结。
[Abstract]:As a new type of pavement regeneration technology, foam asphalt cold recycling technology can reduce the engineering cost while saving energy and environmental protection. It can be said to be an engineering technology with strong practicability and applicability. It is also very suitable for the present situation of maintenance pressure in large and medium repair of highway in our country. This paper studies the material characteristics and climatic conditions of foamed asphalt mixture in Jiaxing area. At the same time, summing up the engineering application experience of this area, trying to find out a set of suitable for Jiaxing area, operational foam asphalt cold recycling ratio design technology and related parameters, This paper provides a reference for the further application of this technology in Jiaxing area. Aiming at the foaming characteristics of asphalt, the comparison tests of two kinds of common asphalt in Jiaxing area are carried out, and the varieties of asphalt are studied and analyzed. The relationship between foaming water consumption and asphalt foaming effect. The milling and planing data of typical cold recycling engineering of foam asphalt in Jiaxing area are selected, and the characteristics of old asphalt pavement and recycled materials in this area are summarized. Based on the practical experience of engineering application in Jiaxing area, the common design methods of cold recycled foamed asphalt mixture are partially optimized, especially for aggregate gradation and asphalt dosage. Based on the actual construction project of Jiaxing section of G320 National Highway, the pavement structure scheme, construction mix ratio design, construction organization and quality control of cold and cold recycling of foamed asphalt factory are formulated. The test and inspection in the later stage of the project are summarized.
