济南沥青砼和沥青碎石有什么区别？
来源：/ 日期：2022-04-29
沥青材料如今可以说是在市场中的需求量越来越好，当然其包含的分类也是多种，很多人分不清沥青砼和沥青碎石有什么区别，下面我们就来分析一番。
Asphalt materials can now be said to be in the market demand is getting better and better, of course, it contains a variety of classification, a lot of people can not tell what the difference is between asphalt concrete and asphalt gravel, we will analyze it.
结构不同
Different structures
沥青砼：沥青混合料的强度主要表现在两个方面。一是沥青与矿粉形成的胶结料的粘结力；另一是集料颗粒间的内摩阻力和锁结力。矿粉细颗粒的巨大表面积使沥青材料形成薄膜，从而提高了沥青材料的粘结强度和温度稳定性。
Asphalt concrete: the strength of asphalt mixture is mainly shown in two aspects. One is the binder formed by asphalt and ore powder; The other is the internal friction resistance and locking force between aggregate particles. The large surface area of fine particles of mineral powder makes bituminous materials form thin films, thus improving the bond strength and temperature stability of bituminous materials.
沥青碎石：骨架空隙结构，粗骨料所占比例大，细骨料很少甚没有。粗骨料可互相嵌锁形成骨架，嵌挤能力强；但细骨料过少不易填充粗骨料之间形成的较大的空隙。该结构内摩擦角φ较高，但黏聚力c也较低。
Bitumen: skeleton void structure, coarse aggregate accounted for a large proportion of fine aggregate little or no. Coarse aggregate can interlock with each other to form a skeleton, with strong interlocking capacity; But too little fine aggregate is not easy to fill the larger gap formed between coarse aggregate. The internal friction Angle φ is higher, but the cohesion c is lower.
矿料级配不同
Mineral gradation is different
沥青砼：沥青混凝土混合料的矿料则级配严格，细矿料和矿粉含量较多，压实后表面较细密。
Asphalt concrete: asphalt concrete mixture of mineral materials is strictly graded, fine mineral materials and ore powder content is more, compacted surface is finer.
沥青碎石：沥青碎石混合料中所含细矿料和矿粉较少，压实后表面较粗糙。
Bituminous gravel: bituminous gravel mixture contains less fine ore and mineral powder, and the surface is rough after compaction.
用途不同
Use different
沥青砼：在土木工程中，济南沥青砼是应用广泛的防水材料和防腐材料，主要应用于屋面、地面、地下结构的防水，木材、钢材的防腐。
Asphalt concrete: in civil engineering, Ji 'nan asphalt concrete is widely used in waterproof materials and anticorrosive materials, mainly used in the roof, ground, underground structure waterproof, wood, steel anticorrosion.
沥青碎石：主要是用于铺设路面结构层。是市政工程和次路面的面层材料。
Asphalt gravel: mainly used for laying pavement structural layer. It is the surface material of municipal engineering and sub-high road surface.
Ji 'nan asphalt concrete and asphalt gravel what is the difference? We have talked about this problem from three aspects, in addition to the transport of asphalt concrete should pay more attention to prevent the emergence of problems. For more information, visit .
