【摘要】：由于近年来交通运输行业的飞速发展,交通量逐年增多,加上甘肃省北方季冻区的气候特点,使得甘肃省的沥青路面易发生车辙、裂缝等道路病害。为了防治沥青路面的早期破坏,改善沥青混合料的使用品质、加强沥青混合料的路用能力、延长路面的使用寿命,许多改性沥青应运而生,其中包括以废弃橡胶粉为原料的橡胶沥青。本文结合国内外已有的研究成果,依托G247线文县东峪口至九寨沟(甘川界)段的路面扩建工程项目,采用室内试验和现场测试的手段,分析研究了橡胶沥青的作用机理、技术性能及沥青混合料的路用性能、级配设计,给出了橡胶沥青路面的施工工艺及质量控制的措施。本文的研究成果和工程实践的经验对橡胶沥青在甘肃省相似工程中的应用有积极的指导作用,具有一定的理论和工程实用价值。
[Abstract]:Due to the rapid development of transportation industry in recent years, traffic volume increases year by year, coupled with the climate characteristics of seasonal frozen areas in northern Gansu Province, asphalt pavement in Gansu Province is prone to rut, cracks and other road diseases. In order to prevent the early destruction of asphalt pavement, improve the use quality of asphalt mixture, strengthen the road capacity of asphalt mixture and prolong the service life of pavement, many modified asphalt have emerged as the times require. These include rubber asphalt made from waste rubber powder. Based on the existing research results at home and abroad, and relying on the pavement expansion project from Dongyukou to Jiuzhaigou (Ganchuan Boundary) of Wenxian County on the G247 Line, this paper analyzes and studies the mechanism of rubber asphalt by means of indoor test and field test. The technical performance, pavement performance and gradation design of asphalt mixture are introduced, and the construction technology and quality control measures of rubber asphalt pavement are given. The research results and engineering practice experience in this paper have a positive guiding effect on the application of rubber asphalt in similar projects in Gansu Province, and have certain theoretical and engineering practical value.
