Izinzuzo zethayela le-asphalt elinezingqimba ezimbili ekuthuthukisweni kwesikhathi esizayo kwemboni yezokuvakasha, izinto zohlelo lophahla zivame ukuba nezitayela ezahlukene, kanti izidingo zezinto zokwakha uphahla ziphakeme kakhulu. Uhlobo lwezinto zophahla lungabhekana nezitayela ezahlukene, okungathiwa zisesicongweni. Ngaphezu kwalokho, ukusebenza kokukhipha amanzi nokushisa kophahla kuyathuthuka. Izinzuzo zethayela le-asphalt: linezimo ezahlukahlukene kanye nobubanzi bokusetshenziswa okubanzi. Okwesibili, ukufudumala. Okwesithathu, ukukhanya okuthwala umthwalo ophahleni, kuphephile futhi kuthembekile. Okwesine, ukwakhiwa kulula futhi izindleko eziphelele ziphansi. Okwesihlanu, lihlala isikhathi eside futhi alikhathazeki ngokuphuka.

Phakathi noBukhosi baseNtshonalanga Zhou obuphakathi nobasekupheleni, amathayili ayesetshenziswa kakhulu; Ngesikhathi soBukhosi baseMpumalanga Zhou, abantu base beqalile ukuqopha amaphethini ahlukahlukene amahle ebusweni bamathayili ukuze bahlobise; EMbusweni waseNtshonalanga Han, kwenziwa intuthuko ecacile kwezobuchwepheshe bokwenza amathayili, kangangokuthi ithayili leshubhu elinethayili eliyindilinga lenziwa lula kusukela ezinqubweni ezintathu kuya enqubweni eyodwa, futhi ikhwalithi yethayili nayo yathuthukiswa kakhulu, ebizwa ngokuthi “ithayili le-Qin brick ne-Han”. Amathayili ngokuvamile anemisebenzi yokungangeni manzi, ukuvikela ukushisa, ukuvikela umsindo, ukulondoloza ukushisa, ukufiphaza kanye nokuhlobisa. Amathayili obumba ayesetshenziswa kakhulu ekuqaleni, bese kuba amathayili acwebezelayo, amathayili e-celadon, amathayili e-asbestos, amathayili esimende, amathayili e-resin okwenziwa, amathayili ensimbi anombala kanye namathayili e-asphalt.

Inzuzo yethayela le-asphalt elinezingqimba ezimbili ukulungisa ithayela le-asphalt ngezipikili ngokuqinile. Lonke ucezu lwesithathu lwethayela le-asphalt kufanele lunqunywe, oluhlanganiswe nongqimba lwesibili lwethayela le-asphalt, kanti unqenqema olungezansi lwethayela le-asphalt kufanele lucwebezele ngesiphetho esiphezulu sendawo yokuhlobisa yengqimba yesibili yethayela le-asphalt. Ngemuva kwalokho, lonke ithayela le-asphalt libekwa ngokulandelana. Ungadabuli uphawu lwepulasitiki ngemuva kwamathayela. Uphawu lwepulasitiki lusetshenziselwa kuphela ukupakisha ukuvimbela ukunamathelana phakathi kwamathayela. Isithunzi esibangelwa umehluko wombala ukwakheka kwethayela ngokwalo. Ithayela ngokwalo linamathela, ukuze ithayela linamathiselwe ngokwemvelo ngaphansi kokukhanya kwelanga ngemva kokugandaya.
