Isembozo Se-Asphalt Esingeyona I-Fiberglass | Isixazululo Sokuqinisa I-Pavement Esiphezulu
Ukubuka Konke Komkhiqizo
I-Fiberglass Nonwoven Asphalt Overlay yethu iyinto esebenza kahle kakhulu, ehlanganisiwe eyenzelwe ukwandisa isikhathi sokuphila komgwaqo ngokuqinisa izindawo ze-asphalt. Uma ihlanganisa umata we-fiberglass oqinile nonwoven ne-asphalt eguquliwe nge-polymer, inikeza ukumelana okuphezulu emifantwini, umswakama, kanye nezimoto eziningi. Ilungele imigwaqo emikhulu, imigwaqo kamasipala, kanye nezindawo zokupaka zezentengiselwano e-US naseCanada.
Izici Eziyinhloko Nezinzuzo
1. Ukuqina Okumangalisayo
- Ukuqinisa i-fiber yengilazi kuyamelana nokucindezeleka kokucindezelwa, kuvimbela imifantu ekhanyayo.
- Ukugqoka kwe-asphalt okuguquliwe kuqinisekisa ukunamathela isikhathi eside kanye nokuguquguquka (-30°C kuya ku-80°C).
2. Ukusebenza Kwesimo Sezulu Sonke
- Imelana nemijikelezo yokuqandisa nokuncibilika (okubalulekile eCanada) kanye nokuchayeka kwi-UV (izifunda eziseningizimu ye-US).
3. Ukufakwa okulula
- Imiqulu elungisiwe kusengaphambili ukuze isetshenziswe ngokushesha; iyahambisana nemishini ejwayelekile yokugandaya i-asphalt.
4. Ukulungiswa Okungabizi Kakhulu
- Yehlisa imvamisa yokulungisa ngo-50% uma kuqhathaniswa ne-overlays yendabuko.
5. Okunobungani nemvelo
- Iqukethe izinto eziphinde zasetshenziswa; amandla okufaka isandla e-LEED®.

Izicelo
- Umsebenzi:
- Izivalo kanye nokuqinisaizindlela ze-asphalt/concrete ezindalangokuvala imifantu ekhona (kufika ku-5mm ububanzi) nokuvimbela ukuqhekeka okukhanyayo.
- Isebenza njengengqimba ephakathi kwezingqimba ze-asphalt ezindala nezintsha, yandisa impilo yendlelaIminyaka engu-8–12.
- Amacala Okusetshenziswa:Inothi Lobuchwepheshe: Iyahambisanaukulungiswa kokushisa kwe-infraredukuhlanganiswa okungenamthungo.
- Ukulungiswa kabusha kwemigwaqo yasemadolobheni (isb., izindawo ezihlangana nemigodi).
- Ukulungisaimifantu yengwenyaemigwaqweni emikhulu ngaphandle kokwakhiwa kabusha okujulile.
-
- Umsebenzi:
- Kufakwe ngaphakathi kwezingqimba ze-asphalt ukuzeukusabalalisa ukucindezeleka komthwalo,ukunciphisa ukugoba kanye nokukhathala lapho kunezimoto eziningi (isb., imithwalo ye-axle engaphezu kuka-80 kN).
- Kuthuthukisa amandla okudonsa ngo40% uma kuqhathaniswa ne-asphalt engaqiniswanga (ngokuhlolwa kwe-ASTM D7460).
- Sebenzisa Amacala:
- Imigwaqo emikhulu: Kubalulekile kakhulu ekugandayweni okuqhubekayo okungenamajoyinti ezindaweni zokwandisa.
- Isikhumulo sezindiza Imigwaqo yezindiza: Imelana nokuqhuma kwejethi kanye nokuchayeka kuphethiloli (amazinga avunyelwe yi-FAA ayatholakala).
- Ezobuchwepheshe Inothi: Kudingaukuhlanganiswa kwe-asphalt exutshwe ngokushisa (i-HMA)ku-150–160°C ukuze kube nokuhlangana okuhle kakhulu.
- Umsebenzi:
Umsebenzi:
Yakha i-isithiyo esingangeningokumelene nokungena kwamanzi, okuvimbela ukugqwala kweziqinisi zensimbi emadekini ebhuloho ekhonkrithi.
Iyamelanaukungena kwe-ion ye-chloride(Ukuhambisana ne-ASTM C1543), kubalulekile ezifundeni ezisogwini.
Amacala Okusetshenziswa:
Ama-Bridge Decks: Kufakwe ngaphansi kwemigqa yokugqoka i-asphalt (isb., amabhuloho ensimbi e-orthotropic).
Ukupaka Ngaphansi Komhlaba: Kuvimba umswakama okhuphukayo kanye nokuchitheka kukawoyela.
Inothi Lobuchwepheshe:Bhangqa nei-bitumen eguquliwe efakwe ithoshiezindaweni eziqondile.
- Umsebenzi:
- Izinhlobo ezikhanyayo (ubukhulu obungu-1.5–2.5mm) zinikeza ukumelana nokuqhekeka ezindaweni ezinesivinini esiphansi nezinomthwalo omncane.
- Ubuso obuqiniswe yi-UV bumelana nokufiphala kanye nokuwohloka emizileni yokungena.
- Izendlalelo Zokusebenzisa: Inothi Lobuchwepheshe: Ilungele ukwenza ngokwakho ngezinketho zokusekela ezinamathelayo ezibandayo.
- Imigwaqo Yokushayela Yasekhaya: Iqeda ukuqhekeka kwesizini ezindaweni ezibandayo.
- Imizila Yomphakathi: Ilungele imigwaqo enakekelwa yi-HOA enezimoto ezingu-10–50 ngosuku.
