I-asphalt ehlanganisiwe i-asphalt vs. I-Hot Mix Asphalt: Uyini umehluko?
Ukukhishwa kwesikhathi:2025-12-08
I-asphalt ebandayo ye-asphalt kanye ne-asphalt eshisayo zombili izinto ezisetshenziswayo ekwakhiweni komgwaqo nokulungisa, kepha zinomehluko ohlukile ngokwemigomo yokwakheka, uhlelo, kanye nokusebenzisa amacala.
I-Cold Mix Asphalt ikhiqizwa ngaphandle kwesidingo sokushisa. Siqukethe ingxube ye-asphalt binder, ehlanganisiwe, kanye nezithasiselo ezihlanganiswe namazinga okushisa akhona. Ngoba ayidingi amazinga okushisa aphezulu wokuxuba, asphalt okuhlanganisa okubandayo ilungele ukulungiswa okwesikhashana namaphrojekthi amancane, njengokugcwalisa imigodi noma ukumiswa kwemifantu emigwaqweni. Kuhle futhi ukugcina nokuhambisa ngoba akudingi ukuthi kugcinwe emazingeni okushisa aphezulu, okwenza kube yisixazululo esisebenza ngempumelelo yokulungiswa kwezimo eziphuthumayo lapho kulungiswa khona okusheshayo. Kodwa-ke, i-asphalt ebandayo ebandayo ayinikezi ukuqina okufanayo kwesikhathi eside njenge-asphalt eshisayo eshisayo.
I-asphalt eshisayo eshisayo, ngakolunye uhlangothi, yenziwa ngokushisa i-asphalt yokushisa okuphezulu, imvamisa cishe ngo-300 ° F kuya ku-350 ° F (150 ° C kuya ku-180 ° C), ngaphambi kokuyixubanisa ne-aggregate. Le nqubo yokufudumeza ivumela ukuthi i-asphalt ibe yinhle kakhulu, okwenza ilungele izinhlelo eziningi ezisindayo zomsebenzi, kufaka phakathi ukwakhiwa kwemigwaqo emikhulu, izindawo ezinkulu zokupaka izindawo, namanye amaphrojekthi amakhulu omgwaqo. I-asphalt eshisayo eshisayo idala indawo enamandla, eqinile kakhulu engamelana namavolumu aphezulu wethrafikhi kanye nezimo zesimo sezulu esibi kakhulu. Kodwa-ke, ukusetshenziswa kwayo kukhawulelwe ngokwengeziwe ngezimo zokushisa, ngoba kudingeka zisetshenziswe ngenkathi kusashisa futhi kungafanele izicelo zesimo sezulu esibandayo.
Ngamafuphi, umehluko osemqoka phakathi kokuhlanganiswa okubandayo kanye ne-asphalt eshisayo eshisayo ekukhiqizeni kwabo nasekusetshenzisweni kwabo. I-Asphalt ebandayo ebandayo ilungele ukulungiswa kwesikhashana noma okuncane, ngenkathi i-asphalt eshisayo ilungele kangcono amaphrojekthi wokwakha umgwaqo amakhulu, ahlala isikhathi eside ngenxa yamandla ayo aphezulu nokuqina.
