Iyini Isitshalo Se-Asphalt Esixutshwe Kahle Futhi Sisebenza Kanjani?

Iyini Isitshalo Se-Asphalt Esixutshwe Kakhulu?

Isitshalo se-asphalt esixubene nokushisa (i-HMA) siyisakhiwo esikhiqiza indlela ye-asphalt yokwakha imigwaqo. Sihlanganisa i-aggregate (njengetshe eliyitshe, isihlabathi, namatshe) ne-asphalt cement, umkhiqizo osuselwa kuphethiloli, emazingeni okushisa aphezulu ukudala izinto zendlela ye-asphalt ezibushelelezi, eziqinile, neziguquguqukayo.

Izingxenye Eziyinhloko Zesitshalo Se-Asphalt Esixutshwe Kakhulu

Isitshalo esijwayelekile se-HMA siqukethe izingxenye eziningana ezibalulekile:

• Amabhini Ahlanganisiwe : Lezi yizitsha zokugcina izinhlobo ezahlukene zezinto ezihlanganisiwe.
• I-Drum Yokomisa : Yilapho i-aggregate ishiswa khona futhi yomiswe ukuze kususwe umswakama.
• Isishisi : Isishisi sishisa i-aggregate ekushiseni okudingekayo, ngokuvamile phakathi kuka-150°C kuya ku-190°C.
• Umbhoshongo Wokuxuba : Yilapho i-aggregate efudumele ixutshwa khona ne-asphalt cement nezinye izithasiselo.
• Ama-Silo Okugcina Izinto : Lawa ma-silo agcina ingxube ye-asphalt eqediwe ngaphambi kokuba ithuthwe iye ezindaweni zokwakha.

Isitshalo Se-Asphalt Esixutshwe Kanjani Sisebenza Kanjani?

Inqubo iqala ngokuthi i-aggregate ifakwe esigubhini sokomisa. I-aggregate iyashiswa futhi yomiswe, bese ixutshwa ne-asphalt cement embhoshongweni wokuxuba. Izilinganiso eziqondile ze-aggregate kanye ne-asphalt cement zilawulwa ngokucophelela ukuqinisekisa ukuthi ingxube ihlangabezana nezindinganiso ezithile.

Ngemva kokuxuba, i-HMA idluliselwa ezindaweni zokugcina izinto. Uma isilungele ukusetshenziswa, ilayishwa emalorini bese ilethwa ezindaweni zokwakha, lapho ibekwa khona futhi icindezelwe ngama-roller neminye imishini esindayo.

Ukusetshenziswa kwe-Hot Mix Asphalt

I-HMA isetshenziswa kabanzi ekwakheni nasekunakekeleni imigwaqo, imigwaqo emikhulu, izikhumulo zezindiza, kanye nezinye izindawo ezigandayiwe. Ukuqina kwayo nokuguquguquka kwayo kwenza ibe yinto efanelekile ezindaweni ezinabantu abaningi.

Izinzuzo ze-Hot Mix Asphalt

I-HMA inikeza izinzuzo eziningana ngaphezu kwezinye izinto zokwakha imigwaqo:

• Ingabekwa phansi futhi ivulelwe ukuthuthwa kwezimoto ngokushesha, okunciphisa ukubambezeleka kokwakhiwa.
• Ihlala isikhathi eside kakhulu futhi ingamelana nemithwalo esindayo kanye nezimo zezulu ezinzima.
• Ingaphinde isetshenziswe, okwenza kube inketho enobungani nemvelo.

Isiphetho

Isitshalo se-asphalt esixubene nokushisa siyindawo ebalulekile yokukhiqiza indlela ye-asphalt esezingeni eliphezulu. Ukuqonda ukuthi isebenza kanjani kanye nezingxenye zayo ezibalulekile kungakusiza ukuthi uqonde ubunzima nokubaluleka kokwakhiwa kwemigwaqo. Kungakhathaliseki ukuthi ungumakhi, unjiniyela, noma umane nje ufuna ukwazi ukuthi imigwaqo yakhiwa kanjani, lo mhlahlandlela unikeza ukuqonda okubalulekile emhlabeni wokukhiqizwa kwe-asphalt.
