沥青玛蹄脂碎石混合料路面应用研究 摘要 沥青玛蹄脂碎石路面是近年来国际与国内新出现的高等级路面，其优良的抗滑性能和抗车辙性 能为世人瞩目，本文根据国内外的实践经验，结合在I.程实际中室内外试验结果，系统阐述了SMA 的发展状况，并对其组成特点、材料要求及配合比提出了适合我国的国情的推荐方案。全文共七章。 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。 关键词:路面结构分析抗车辙性能抗滑性能研究 河!七不业大学硕卜学位论史 RESEARCH ON APPLICATION OF SMA Abstract SMA has received much attention recently by Internationally and nationally as a promising solution to high grade highways, mainly due to the fact that it has excellent capability of anti-slide and anti-track .This paper is based on our comprehensive testing experience (indoor and outdoor) combined with testing result of the real construction work which took places in both our country and other countries in order to explain the SMA the I propose practical solutions that addresses the following issues:(a) ee Thth ingredients of SMAs feature, (b)requirement of the materials and their ratios. paper proceeds as follows. Chapter one presents the development of SMA in recent years and highlight the introduction. I summarize 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.
