修路用的瀝青到底是什么

來源:http://guixin.net.cn/ 日期:2022-09-24
其實(shí),對(duì)于汽車而言,主要的還是道路,畢竟沒有道路汽車該怎么行駛呢?對(duì)吧?那么大家有沒有仔細(xì)觀察過與汽車親密的路面呢?它是怎么樣的?它是由什么構(gòu)造而成的呢?濟(jì)南瀝青料廠家為您講解。
In fact, for cars, the main thing is the road. After all, how can I drive without a road car? Right? So have you carefully observed the roads close to cars? What is it like? What is it constructed from? Jinan asphalt manufacturer will explain to you.
以前的時(shí)候,大部分的公路路面都是水泥路?,F(xiàn)如今,有許多都改造為瀝青路面。這種改造期間,會(huì)給人們的出行造成了許多的不便,也有人會(huì)不喜歡這個(gè)味道而心生埋怨,因此也會(huì)聽到各種非議:瀝青是什么?水泥路不是挺好的嗎?為什么要改造水泥路?有什么目的嗎?瀝青路又有什么好處?別急,下面就讓小編來為你們仔細(xì)解答。今天算是長見識(shí)了
In the past, most roads were cement roads. Nowadays, many of them are transformed into asphalt pavement. During this transformation, it will cause a lot of inconvenience to people's travel, and some people will not like the taste and complain, so they will also hear various criticisms: What is asphalt? Isn't the cement road very good? Why should cement roads be reconstructed? What's the purpose? What are the benefits of asphalt roads? Don't worry. Now let's make up for you to answer carefully. I've seen a lot today
,我們先來了解一下瀝青路面這個(gè)東西。瀝青路面主要是由瀝青材料制成的,輔以粗集料和細(xì)集料。在瀝青材料當(dāng)中,則又可分為煤焦、石油、天然三種。煤焦瀝青是燒焦之后殘留在容器內(nèi)的物質(zhì);石油瀝青是原油蒸餾之后的殘留物;
First of all, let's learn about asphalt pavement. Asphalt pavement is mainly made of asphalt materials, supplemented by coarse aggregate and fine aggregate. Among asphalt materials, they can be divided into coal coke, petroleum and natural materials. Coal tar pitch is the substance left in the container after burning; Petroleum asphalt is the residue of crude oil distillation;
濟(jì)南瀝青料
天然瀝青一般存在于地下,儲(chǔ)存在礦里面或者是地底下。瀝青有分一二三個(gè)等級(jí),一等級(jí)為佳,二等級(jí)次之,三等級(jí)差。使用何種等級(jí)的瀝青依照道路的情況而定,一般來說,修路用差的一個(gè)等級(jí),省級(jí)的用次一些的等級(jí),而用的是佳等級(jí)的。
Natural asphalt generally exists underground, stored in mines or underground. There are one, two or three grades of asphalt, the first grade is better, the second grade is second, and the third grade is poor. The grade of asphalt used depends on the situation of the road. Generally speaking, the grade used for road construction is poor, the grade used for provincial construction is inferior, and the grade used is good.
如果是修路的話,大部分使用都會(huì)是煤焦瀝青和石油瀝青,因?yàn)檫@些都是剩下來的,較為廉價(jià)。畢竟是修路嘛,不必要用到那么的。
If the road is to be built, most of them will be coal tar asphalt and petroleum asphalt, because these are the leftovers and are relatively cheap. After all, it's road building. It's unnecessary to use such advanced skills.
其次,瀝青路面有著太多的益處,它的承受能力夠強(qiáng),當(dāng)車輛的重量作用到路面上的時(shí)候,能夠很好地承受;它的可塑性很強(qiáng),當(dāng)車輛太重承受不來的時(shí)候,能夠變型;它能夠保證車輛運(yùn)行更加;他能夠降低噪音。
Secondly, asphalt pavement has too many benefits. Its bearing capacity is strong enough to bear well when the weight of vehicles acts on the pavement; Its plasticity is very strong. When the vehicle is too heavy to bear, it can be deformed; It can ensure more safe vehicle operation; He can reduce the noise.
有了瀝青路面,我們所處的環(huán)境會(huì)更加地安靜;有了瀝青路面,我們的使用汽車會(huì)更加;有了瀝青路面,我們的汽車使用年限會(huì)更久。更多相關(guān)事項(xiàng)就來我們網(wǎng)站http://guixin.net.cn進(jìn)行咨詢了解吧!
With asphalt pavement, our environment will be more quiet; With asphalt pavement, our use of cars will be safer; With asphalt pavement, our cars will last longer. Come to our website for more information http://guixin.net.cn Consult and understand!
