【摘要】 我国从90年代开始了大规模的高等级路面尤其是沥青路面建设,到目前为止,一方面许多沥青路面仍在开工建设,造成我国道路沥青、砂石材料紧缺;另一方面许多沥青路面相继进入了大修阶段,翻修下来的大量旧料不但堆放困难,而且如果处理不当,就会对土壤、水源产生较严重的污染。因此无论是从能源的角度看,还是从环保的角度看,旧沥青路面再生利用目前在我国都应该得到重视和发展。论文以沥青路面养护工程为研究背景,分析了厂拌热再生技术的施工方法、施工流程并指出厂拌热再生技术的工艺要点及关键技术。本文还对厂拌热再生沥青混合料的技术性能与经济效益进行了分析。根据再生沥青混合料实际工程运用,通过使用效果和经济效益综合分析,表明沥青路面厂拌热再生技术是一种非常适宜的道路维修改造方式,应该在高速公路沥青路面大修工程中,尤其是缺乏砂石材料的地区推广应用。本论文结合公路养护工程机械化施工实践,考虑影响沥青混凝土路面养护工程中机械化施工系统各机械的制约因素、应用概率论、数理统计、随机服务系统理论、公路工程机械化施工系统理论以及技术经济指标评价方法,深入研究了沥青混凝土路面养护工程中机械化施工系统,各个机械在施工作业中各个时期的工作状态,相互联系、相互制约的规律以及相应的技术经济评价。在此基础上,提出了基于厂拌热再生的沥青混凝土路面养护工程中机械化施工系统的资源配置方法。更多还原

【Abstract】 Since the 1990s, lots of high-grade pavements, especially flexible pavements, have been constructed in our country, which results in lake of bitumen and aggregate. Mean while, many flexible pavements have become old and need repair. Old asphalt mixtures need large field for piling and are disposed hardly. If disposed incorrectly, they will pollute soil and water source. So, in order to save the sources and protect environment, it is important to develop recycling old flexible pavements in our country now.Based on the asphalt pavement maintenance, the thesis analyzes construction method, construction procedure of hot central plant recycling technology and the critical technologies of hot central plant recycling technology.It also analyzes the technique property, economical and social results of Hot Recycled Mixture of asphalt pavement.Fourthly, based on the freeway project, construction techniques of hot recycled mixture have been probed into. Finally, the paper analyzes the technique property, economical and social result of hot recycled mixture of asphalt pavement. It indicates that hot central plant recycling technology is a favorable method for freeway maintenance and reconstruction and especially should be applied in the region where is scarce of aggregate.This paper which applying the theory probability mathematical statistics ,the theory of random service system,the theory of highway engineering mechanization construction and the method of evaluation of economy is deeply into the study of the machines’states during asphalt pavement constructing, the rules of relation and limit and the evaluation of technology and economy ,under considering of the practice of highway engineering mechanization construction system of asphalt pavement.upon the able, it raises an appoint of optimum configuration of resource of mechanization construction system of asphalt pavement.更多还原
