【摘要】 公路建设是一项投资大,建设周期长的工程项目,它在国民经济建设和现代国防建设中的地位举足轻重。如何有效利用有限的的资金,促进公路建设的迅速,就有必要从科学的、实事求是的观点出发,对道路建设新材料进行理论研究和实践操作进行大胆探索。 路面冷再生技术就是将旧沥青路面材料(包括沥青面层和部分基层材料),经过锨刨加工进行重复利用,并根据再生后结构层的结构特征,适当加入部分新骨料或细集料,按比例加入一定量的外加剂和适量的水,在自然环境下连续完成材料的一系列加工工艺,重新形成结构层的一种工艺方法。 本文从冷再生技术的特点出发,分析了路面冷再生技术的优越性,并通过室内试验的方法阐述了冷再生技术的反应机理,不同添加剂的种类和剂量对性能的影响。得出了适宜的再生材料级配范围、抗压强度、抗压回弹模量、劈裂强度等主要设计参数值,通过现场铺筑试验段检测,室内分析的方法,检验室内试验结论,以用于对室内试验结论的修正补充及完善。同时总结了冷再生基层、底基层的质量检测和评价标准。 最后本文详尽地分析了应用沥青混凝土旧路现场冷再生技术经济性,为路面结构设计、施工、监理等单位应用冷再生技术提供了可靠的科学依据。总而言之,冷再生技术的开展与应用必将节约大量的资金,减轻环境污染,带来不可估量的经济效益和社会效益。
【Abstract】 The highway construction is a project that needs great money and lasts a long period. It hold the balance of civil economy and modern national defense, it ask for theory research and carry out manipulation of new material from the view of scientific and being practical and realistic to make use of limited financing to promoted highway construction.Pavement cold-in place recycling is a new technique of form pavement structure, it include three steps: the fist step is the processing of old asphalt pavement material including asphalt pavement and parts of road base material, then add some new bone-material or thin material to these material according to the characteristic of cold recycling structure, at the same time add some water and in addition matter according the quantity of material, at last deal with these material in environment condition to form an new structure.Based on the characteristic of cold recycling technology, its advantage is analyzed in this paper. The effect of different in-addition and dose of addition on material capability is interviewed by in-door experiment. The parameter value of feasible scope, resist-intention, resist-intention elastic module and crack intention is given out. Experiment result is tested through in-place examine of experiment road and analysis to correct and perfect the experiment conclusion, at the same time quality inspect and evaluate standard is summarized in this paper.At lasts the economy character of application of old asphalt concrete pavement in-place cold recycling technology given out in detail, it can be used to be the scientific base of pavement structure design, construct, and supervise of apply cold recycling technology. To sum up, the theory research and application of cold recycling technology will save lots of money, alleviate environment pollution and bring up unlimited economy and society benefit.
