濟(jì)南瀝青砼和瀝青碎石有什么區(qū)別？

來(lái)源：http://m.apdetong.cn/ 日期：2022-04-29

　　瀝青材料如今可以說(shuō)是在市場(chǎng)中的需求量越來(lái)越好，當(dāng)然其包含的分類(lèi)也是多種，很多人分不清瀝青砼和瀝青碎石有什么區(qū)別，下面我們就來(lái)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.

　　結(jié)構(gòu)不同

　　Different structures

　　瀝青砼：瀝青混合料的強(qiáng)度主要表現(xiàn)在兩個(gè)方面。一是瀝青與礦粉形成的膠結(jié)料的粘結(jié)力；另一是集料顆粒間的內(nèi)摩阻力和鎖結(jié)力。礦粉細(xì)顆粒的巨大表面積使瀝青材料形成薄膜，從而提高了瀝青材料的粘結(jié)強(qiáng)度和溫度穩(wěn)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.

　　瀝青碎石：骨架空隙結(jié)構(gòu)，粗骨料所占比例大，細(xì)骨料很少甚至沒(méi)有。粗骨料可互相嵌鎖形成骨架，嵌擠能力強(qiáng)；但細(xì)骨料過(guò)少不易填充粗骨料之間形成的較大的空隙。該結(jié)構(gòu)內(nèi)摩擦角φ較高，但黏聚力c也較低。

　　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.

　　礦料級(jí)配不同

　　Mineral gradation is different

　　瀝青砼：瀝青混凝土混合料的礦料則級(jí)配嚴(yán)格，細(xì)礦料和礦粉含量較多，壓實(shí)后表面較細(xì)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.

　　瀝青碎石：瀝青碎石混合料中所含細(xì)礦料和礦粉較少，壓實(shí)后表面較粗糙。

　　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

　　瀝青砼：在土木工程中，濟(jì)南瀝青砼是應(yīng)用廣泛的防水材料和防腐材料，主要應(yīng)用于屋面、地面、地下結(jié)構(gòu)的防水，木材、鋼材的防腐。

　　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.

　　瀝青碎石：主要是用于鋪設(shè)路面結(jié)構(gòu)層。是市政工程和次高級(jí)路面的面層材料。

　　Asphalt gravel: mainly used for laying pavement structural layer. It is the surface material of municipal engineering and sub-high road surface.

　　濟(jì)南瀝青砼和瀝青碎石有什么區(qū)別？我們從三個(gè)方面來(lái)講了講這個(gè)問(wèn)題，此外瀝青砼的運(yùn)輸方面也要多注意，防止問(wèn)題的出現(xiàn)。更多內(nèi)容了解就來(lái)網(wǎng)站m.apdetong.cn看看吧。

　　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 m.apdetong.cn.
