沥青玛蹄脂碎石混合料 meaning in Chinese
stone mastic asphalt
Examples
- In addition , due to the good thermal conductivity of steel materials , the pavement layer upon the deck should have good thermal stabilities and low temperature deformation abilities . in terms of paving materials and erecting methods , the steel deck pavement systems adopted in the world can be generalized into four types : the first one is the gussasphalt . then is the mastic asphalt
从铺装材料和施工方法来分类，目前世界上所采用的钢桥面铺装体系，概括起来大致有四类：第一类为高温拌和浇注式沥青混凝土( gussasphalt ) ，第二类为沥青玛蹄脂混合料( masticasphalt ) (实际上也是浇注式沥青混凝土，只是拌和、摊铺工艺有所不同) ，第三类为沥青玛蹄脂碎石混合料( stonemasticasphalt ，简称sma ) ，第四类为环氧树脂沥青混合料( epoxyasphalt ) 。 - 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。
