Ifu ya reberi yahinduwe bitumen (BitumenRubber, yitwa AR) ni ubwoko bushya bwibikoresho byo mu rwego rwo hejuru. Nubwoko bushya bwibintu byujuje ubuziranenge bikozwe mu ifu ya reberi ikozwe mu mapine y’imyanda, yongeweho nkuguhindura bitumen fatizo. Byakozwe binyuze murukurikirane rwibikorwa nkubushyuhe bwo hejuru, inyongeramusaruro hamwe nogosha kuvanga mubikoresho bidasanzwe. Ibikoresho. Irashobora kwagura ubuzima bwa serivise yubuso bwumuhanda, kugabanya urusaku, kugabanya kunyeganyega, kunoza ubushyuhe bwumuriro no gucana ubushyuhe, no kunoza ubukonje. Mubikorwa byahurijwe hamwe na bitumen iremereye cyane, ifu yipine ya rubber hamwe nuruvange, ifu ya reberi ikuramo resin, hydrocarbone nibindi bintu kama muri bitumen, kandi igahinduka nuruhererekane rwumubiri na chimique kugirango ibe nziza kandi yongere ifu ya rubber. Ubukonje bwiyongera, ingingo yoroshye yiyongera, kandi ubwitonzi, ubukana, hamwe na elastique ya reberi na bitumen byitabwaho, bityo bikazamura imikorere yumuhanda wa rubber bitumen.
"Rubber powder yahinduwe bitumen" bivuga ifu ya reberi ikozwe mumapine yimyanda, yongeweho nkibihindura bitumen fatizo. Byakozwe binyuze murukurikirane rwibikorwa nkubushyuhe bwo hejuru, inyongeramusaruro hamwe nogosha kuvanga mubikoresho bidasanzwe. ibikoresho bifatika.
Ihame ryo guhindura ifu ya reberi yahinduwe bitumen ni ibikoresho byahinduwe na sima ya bitumen byakozwe nuburyo bwuzuye bwo kubyimba hagati yifu yifu ya rubber na matrix bitumen bivanze nubushyuhe bwo hejuru. Ifu ya reberi yahinduwe bitumen yazamuye cyane imikorere ya bitumen ishingiro, kandi iruta bitum yahinduwe ikozwe muburyo busanzwe bukoreshwa nka SBS, SBR, EVA, nibindi. Ukurikije imikorere yayo myiza nintererano nini mukurengera ibidukikije, abahanga bamwe guhanura ko ifu ya rubber yahinduwe bitumen biteganijwe ko izasimbura bitumen ya SBS.
akarusho

Ifu ya reberi irashobora kongerwaho bitumen mukubaka imihanda ninzira nyabagendwa. Iyi porogaramu ntabwo yari igamije nkisoko yo gukoresha amapine yimyanda, ahubwo yari igamije kunoza imitungo ya bitumen kurwego rusa nubwa bitumen yo mu rwego rwo hejuru irimo elastomeri nshya. Ibyiza byo kongeramo ifu ya rubber muri bitumen harimo kugabanya imyumvire yumuhanda ucika (cyane cyane ahantu hakonje), kunoza igihe kirekire cyumuhanda, kurwanya amazi no guhagarara neza kwa kaburimbo. Rubber-yahinduwe bitumen iraramba, imara impuzandengo yimyaka irindwi kurenza ivangwa rya bitumen gakondo.?
Rubber ikoreshwa kuri bitumen yahinduwe ni polymer yoroheje cyane. Ongeramo ifu ya rubber yibirunga kuri bitumen fatizo irashobora kugeraho cyangwa ikarenga ingaruka zimwe na styrene-butadiene-styrene block copolymer yahinduwebitumumen. Ibiranga ifu ya rubber yahinduwe bitumen harimo:
1
2. Ubushyuhe bukabije buragabanuka. Iyo ubushyuhe buri hasi, bitumen iba yoroheje, bigatera guhagarika umutima muri pavement; iyo ubushyuhe buri hejuru, pavement iba yoroshye kandi igahinduka bitewe nibinyabiziga bitwaye. Nyuma yo guhindurwa nifu ya reberi, ubushyuhe bwubushyuhe bwa bitumen burahinduka kandi birwanya umuvuduko wacyo. Coefficient ya viscosity ya reberi yifu yahinduwe bitum iruta iya bitumen fatizo, byerekana ko bitum yahinduwe ifite imbaraga nyinshi zo kurwanya ihindagurika.
3. Ubushyuhe buke bukorwa neza. Ifu ya reberi irashobora kunoza ubushyuhe buke bwa bitumen no kongera ubworoherane bwa bitumen.
4. Kongera imbaraga. Mugihe ubunini bwa firime ya rubber bitumen yometse hejuru yamabuye yiyongera, umuhanda wa bitumen urwanya kwangirika kwamazi urashobora kunozwa kandi ubuzima bwumuhanda burashobora kongerwa.
5. Kugabanya umwanda w’urusaku.
6. Ongera gufata hagati yipine yimodoka nubuso bwumuhanda no kunoza umutekano wo gutwara.
kubura
Nyamara, gukoresha ifu ya reberi murubu buryo byongera igiciro cya bitumen, kandi kongeramo ifu ya rubber kuri bitumen bituma imvange ya bitumen igorana kuyifata (byoroshye gukomera) kandi byongera igihe cyo gukora. Rimwe na rimwe, bitumen irimo ifu nini ya reberi byoroshye gufata umuriro mugihe cyo gushonga, bityo rero birasabwa ko ibirimo ifu ya rubber muri bitumen yahinduwe bigomba kuba munsi ya 10%.
