【摘要】：近年来,沥青路面再生技术越来越受到人们的重视,而对于这项技术的研究过程中,对回收料本身性质的了解则是基础中的基础,本篇论文主要介绍回收料本身的性质。在本篇论文的研究中,同时选取了不同地区的三种旧料。首先,主要对RAP料的颗粒组成进行分析,包括三个部分,分别是筛分析,抽提前后的级配变化分析,以及回收料的密度分析。通过分离抽提试验,对沥青本身的变化以及在旧料中的分布情况进行分析;其次,在对旧料中的沥青进行大量的抽提回收试验过程中,发现试验过程中的某些步骤可能对旧沥青的性能产生一定的影响,通过做对比试验,找出试验过程中可能对旧沥青的性能产生影响的因素并提出方法解决。本文分别研究了矿粉,三氯乙烯,以及他们的共同作用对沥青性能的影响,并提出方法来解决这种影响,使其可以准确的了解旧料中沥青本来的性能。最后,通过分析微波加热沥青的优点,提出将微波加热沥青的方法应用于阿布森法当中,有一定的可行性。本文所研究的旧料级配变化这部分内容,为日后的热再生混合料的级配设计提供了一些参考数据,在用阿布森法对沥青进行的抽提过程中,通过一定的方式可以抽提到到更纯净的沥青,同时提出将微波加热方式运用阿布森法的试验装置中,但没有准确的试验装置设计,希望在未来的学习过程中,可以将旧料本身的变化与再生混合料的性质变化联系起来,在这方面有一定的研究。
[Abstract]:In recent years, more and more attention has been paid to the asphalt pavement regeneration technology, and in the research process of this technology, the understanding of the properties of the recycled material is the basis of the foundation. This paper mainly introduces the properties of the recycled material itself. In the research of this paper, three kinds of used materials from different regions are selected. Firstly, the particle composition of rap is analyzed, including three parts: sieve analysis, gradation analysis before and after extraction, and density analysis of recycled material. The variation of asphalt itself and its distribution in used materials are analyzed through separate extraction test. Secondly, in the course of a large number of extraction and recovery tests of asphalt in used materials, It is found that some steps in the test process may have a certain effect on the performance of the old asphalt. Through the comparative tests, the factors that may affect the performance of the old asphalt during the test process are found out and the solutions are put forward. In this paper, the effects of mineral powder, trichloroethylene and their common action on asphalt properties are studied, and some methods are put forward to solve this effect, so that they can accurately understand the original properties of asphalt in old materials. Finally, by analyzing the advantages of microwave heating asphalt, it is put forward that it is feasible to apply microwave heating asphalt method to Abson method. The change of gradation of used materials studied in this paper provides some reference data for the gradation design of hot recycled mixture in the course of extraction of asphalt by Abson method. The purer asphalt can be extracted in a certain way, and it is proposed that the microwave heating method can be used in the test device of Abson method, but there is no accurate design of the experimental device, and it is hoped that in the future study process, The change of used material itself can be linked with the change of properties of recycled mixture.
