Imeko Iindlela kuxhomekeka ekuthotyelweni asphalt nokufakelwa technology

Isibakala sokuba loo asphalt, uluntu eyaziwa ixesha elide. asphalt Natural (nentlaka intaba equka umxube yebhitumene ngezinto yezimbiwa) ezisetyenziswa amaYiputa amandulo namaFenike njenge Umatshini kwi ukwakhiwa kwezakhiwo kunye neenqanawa. South American AmaNdiya wasebenzisa asphalt ukuba ityalwa amaphenyane zabo. Asphalt eyasetyenziswa amaYiputa ukuqwayita, kwaye East awo ingqalelo njengeyeza. Ukongeza, asphalt zendalo wakhupha ebhedini kuLwandle oluFileyo ukusuka, kusetyenziswa (kwaye sebenzisa) ukudala ivanishi kwakunye ipeyinti.

Ukusetyenziswa asphalt eyenziweyo (ngebhitumene umxube ubunjwe, ilitye nakhandiweyo, isanti, izimbiwa umgubo) njengoko ekufanisweni yokukwazi wendlela yaqala ngenkulungwane XIX ekupheleni eYurophu kunye USA. Ngelo xesha saqalisa ukuba ukufaka itela kunye eRashiya.

Kakade ke, ekubeni asphalt ngokubekwa ubugcisa, nemveliso yayo unenzondelelo iinguqu ezinkulu, kodwa imigaqo esisiseko kuhlala injalo.

ukwakhiwa kwendlela Modern

Le meko ibalulekileyo kuba traffic oluqhelekileyo inkqubo yokwenza iipropati endleleni esiqinileyo. Ngaphandle ingeniso yesiqhelo kweendlela mihla eligangathiweyo phantse nzima, ngoko ke nokwakhiwa yemoto yinto ephambili naliphi na ilizwe.

Ukuthotyelwa asphalt ngokubekwa ubuchwepheshe kunye nokusebenza yayo ezinxulumene ngqo imveliso kunye nomgangatho kolawulo izinto ezisetyenziswayo ukwenza iindledlana igada. Ukungaphumeleli ukuthobela iziphumo ukusilela ngaphambi endleleni.

Le mpumelelo bezenzululwazi kwenza kube lula ukuqhubeka iphucule njengenxalenye ukwakhiwa le tela, kwaye yonke inkqubo yemveliso kulungiswa indlela.

Ukuba sithethe netheknoloji asphalt, nto yenziwa ngezigaba ezine:

• base noqeqesho;
• amalahle asphalt ukuba athambe;
• yokubekwa asphalt kwisiseko;
• Lothuli-asphalt nekhompaktha ngenxa Kuqukaniswa kwaye ilungelelanise ngayo.

Ekugqityweni la manyathelo, le tela kufuneka ixesha ngaphambi kokuba ayengawokuphilisa epheleleyo kunye nokufumana amandla yoyilo.

Le iteknoloji ithetha izithintelo eziqatha komyalelo yezenzo, ukuthobela kunye nezithintelo zemozulu zemozulu. Ukungaphumeleli ukulandela ezi mfuno (umz, ukulandelelana ingqokelela kakuhle okanye obushushu aphantsi, imvula) kukhokelela ekubeni egangathiweyo uya kuhlala ngaphantsi kunesiqhelo.

Nkqu ukubambelela ngokungqongqo bonke ubugcisa itela akukho siqinisekiso sokuba endleleni ayidingi ukugcinwa ngakumbi kunye nokulungiswa kwangexesha.

Ukusetyenziswa asphalt abandayo ukulungiswa kwendlela

Le izinto esanda kutshanje kwilizwe lethu. Yenziwe ukusuka asphalt oluqhelekileyo Polymer-kwafakwa iqabaka kunye plasticizing nezongezelelo longeziwe. asphalt Cold ngokubekwa iteknoloji lula kakhulu inkqubo wokulungisa indlela, ekubeni kuvumela ukwenza kuluhlu lobushushu olubanzi. It ingafakwa kumaqondo obushushu asezantsi (-15 ° ^C). Ukongeza, imisebenzi zendlela yenziwe semvula. Kuba nithi, kubanda asphalt ayifuni pre-unyango nokwaleka primer wazilungisa. Kodwa inzuzo eyona obalulekileyo asphalt ebandayo, - netheknoloji ngokubekwa le nto ayithethi ufuna izinto zokusebenza ezithile. Kwanele ukuba kuso potholes okanye umhadi kunye Umhlakulo ebulungelelanisile, emva koko iqala inqubo polymerization kunye Musiqisi lukhuni ngokukhawuleza. Njengoko ngexabiso, ukuba ngaba kuthelekiswa iindleko yolondolozo lwamathuba kweendlela kunye asphalt eqhelekileyo, kuvela ukuba ukusetyenziswa asphalt ebandayo iya kuba zitshiphu.
