- Except this , it also having inspected to use the sbs , the pe and the combination material of sbs and pe to analyze the influence to the function of material road
同时也考察了用sbs ， pe ， sbs和pe复合改性后的沥青结合料对混合料路用性能的影响。 - This paper gives a brief introduction of the formation mechanism of sma and the handing property of pavement from the aspects of theory and research . at the same time , this paper also studies the effect of aggregate size on road - related performance in some different grads . except , it also having inspected to use the sbs , the pe and the combination material of sbs and pe to analyze the influence to the function of material road
沥青玛蹄脂碎石混合料( sma )以其温度稳定性好、抗滑性能优良、低噪音、使用耐久等优点在公路建设中越来越受到重视，本文对sma组成特点，强度形成机理与路面使用性能从理论和试验研究角度进行论述，并针对不同级配的沥青玛蹄脂碎石混合料，分析了粗、细集料的粒径变化对其路用性能的影响，同时也考察了用sbs 、 pe 、 sbs和pe复合改性后的沥青结合料对混合料的路用性能影响。 - This thesis for the first time bases its analysis on the maintenance characteristics and repair mechanisms for crack filling and pothole repair in asphalt roads . it analyzes the properties of the aggregate and the bituminous binder in patching materials , and further analyzes the compatibilities of the aggregate and the bituminous binder , patching materials and old pavement materials . furthermore , it determines the grading types , the mineral aggregate gradations , the application rate of asphalt , the principle of selecting component materials and the air void
本文首次依据沥青路面裂缝填封和坑槽修补的维修特性和修补机理，全面分析了修补材料中集料与沥青结合料应具备的性能要求，并对集料与沥青结合料、修补材料与原有路面材料的相容性进行了深入的分析，同时分析确定了修补材料的级配类型、矿料级配、沥青用量范围、组成材料的选用原则及空隙率等。 - I summarize the development of sma in recent years and highlight the research problems related to and their signifances in chapter 2 . i introduce the characteristic of sma " s compose in chapter 3 ; i discuss the mechanism of sma in chapter 4 ; chapter 5 focuses on the requirement imposed on the ingredients of sma , such as asphaltum combined material , , thick or thin material and fibre stabilization material ; new theory to guide the design of ratio of sma ingredients are proposed in chapter 5 ; i brings forward the combined material design of ratio of sma in chapter 6 ; in chapter 7 i sum up the essential points of the paper and explains the problems happened during experiment to expect more improvement
第一章绪论，提出了对sma进行研究的目的与意义，第二章对近年来sma在国内外发展情况进行了简单介绍；第三章介绍了sma的组成特点；第四章综合介绍了sma的作用机理；第五章介绍了sma对沥青结合料、粗集料、细集料、填料、纤维稳定剂等的要求；第六章提出了sma混合料配合比设计方案；第七章总结全文要点，并就实践(实验)过程中存在的问题进行说明，以期进一步提高。 - Secondly , making use of the road condition and date of different districts of hebei province , the main diseases of road are analyzed , and combined with the local climate , the factors that cause these diseases are analyzed too . this article discusses the factors , including the quality of asphalt and aggregate , gradation and bituminous quantity , effect on the performance of asphalt mixture . finally , through some new key technical index , including the high - temperature rut resistance , low - temperature crack resistance , and water stability of asphalt pavement , the material types , material grade and pavement structure have been put forward to be fit for asphalt pavements of every area of hebei province
其次，通过对全省各地市的路况、气候等资料进行实地调查，利用收集上来的资料分析河北省的主要道路病害，并结合当地的气候情况，分析病害的主要类型及特征，找出病害的主导因素，并利用一些新的关键性指标(如试验方法、评定指标等)来分析沥青路面的高温抗车辙性、低温抗裂性和水稳定性等沥青结合料和沥青混合料的相关路用性能。
