Itiyela elinombala, elaziwa nangokuthi usimende onemibala, liwusimende olingisa izingxenye ze-petroleum asphalt futhi lilungiswa ngokuhlanganisa i-petroleum resin ne-SBS modifier nezinye izinto zamakhemikhali. Le asphalt ngokwayo ayinemibala noma ayinambala, kodwa i-Dark brown, eminyakeni yamuva nje, ibizwa ngokuthi i-asphalt enemibala ngenxa yemikhuba yemakethe. Njengamanje, imigwaqo kakhonkolo yetiyela enombala yaseShayina ingahlukaniswa ibe izinhlobo ezimbili ezinkulu: uhlobo lokuqala lwakhiwe ngokusebenzisa i-asphalt binder esobala noma eguquguqukayo njengesibophezelo, bese kwenezela izibala zombala ezingaphili engxubeni yetiyela; uhlobo lwesibili Lwenziwe ngosimende obala noma okhanyayo. Yakhiwa ngokuxuba amaminerali anemibala yemvelo njengama-aggregates. Ngakho-ke yiziphi izici zomgwaqo okhonkolo we-asphalt onemibala?

Hlobisa idolobha, uthuthukise indawo yomgwaqo, futhi ubonise isitayela sasemadolobheni. Isetshenziswa ngokukhethekile emigwaqweni yabahamba ngezinyawo, ezindaweni zezwe, izikwele, amapaki, imigwaqo nezinye izindawo. Ihambisana notshani obuluhlaza obuzungezile, izihlahla, izimbali, njll., ngaleyo ndlela ihlobise imvelo futhi inikeze abantu umuzwa wesitayela. Jabulela ubuhle. Inomsebenzi wokuhlela nokulawula isiminyaminya, futhi isetshenziswa ngokukhethekile ukuhlukanisa izingxenye zemigwaqo nemizila enemisebenzi ehlukene ukuze kuthuthukiswe umphumela wokuqashelwa komgwaqo, umthamo wethrafikhi womgwaqo nokuphepha kwethrafikhi. Inokusebenza kahle komgwaqo. Ngaphansi kwethonya lamazinga okushisa ahlukene kanye nezindawo zangaphandle, ukuzinza kwayo kokushisa okuphezulu, ukumelana nokulimala kwamanzi nokuqina kuhle kakhulu, futhi akubonakali ukuwohloka, ukukhishwa kwefilimu ye-asphalt, njll, futhi kunobisi oluhle lokubopha ngesendlalelo sesisekelo. . Umbala ugqamile futhi uhlala isikhathi eside, awufihli, ungamelana nezinga lokushisa eliphakeme elingu-77°C namazinga okushisa aphansi angu-23°C, futhi kulula ukuwunakekela. Ngokusebenza okuqinile kokumuncwa komsindo, amathayi emoto ngeke akhiphe umsindo oqinile ngenxa yokucindezelwa komoya lapho egingqika ngesivinini esikhulu emgwaqeni, futhi angamunca omunye umsindo ovela ngaphandle. Inokunwebeka okuhle nokuguquguquka, ukuzwa kahle kwezinyawo, kufanelekile ukuhamba ngabantu abadala, futhi inokusebenza okuhle kokulwa nokushelela ebusika.
