Muri iki gihe, umuhanda wa asfalt ukoreshwa cyane mu kubaka umuhanda kubera ibyiza byinshi. Kugeza ubu, dukoresha cyane cyane bitumen ishyushye hamwe na emulisile bitumen mukubaka pavement ya asfalt. Bitumen ishyushye itwara ingufu nyinshi zubushyuhe, cyane cyane umucanga nibikoresho bya kaburimbo bisaba ubushyuhe bwo guteka. Ibidukikije byubaka kubakoresha birakennye kandi imbaraga zumurimo ni nyinshi. Iyo ukoresheje biti ya emulisiyumu yubwubatsi, gushyushya ntibisabwa kandi birashobora guterwa cyangwa kuvangwa kugirango bishyirwemo ubushyuhe bwicyumba, kandi pavement yinyubako zitandukanye irashobora gushyirwaho kaburimbo. Byongeye kandi, bitumen emulisiyumu irashobora gutemba ubwayo mubushyuhe bwicyumba, kandi irashobora gukorwa muri biti ya emulisile yibitekerezo bitandukanye nkuko bikenewe. Nibyoroshye kugera kuri firime ya asfalt isabwa mugusuka cyangwa gucengera murwego, bidashobora kugerwaho na bitumen ishyushye. Hamwe nogutezimbere buhoro buhoro umuyoboro wumuhanda hamwe no kuzamura ibisabwa mumihanda yo hasi, ikoreshwa rya bitumen emulisile rizaba rinini kandi rinini; hamwe no kongera ubumenyi bwibidukikije no kubura ingufu gahoro gahoro, igipimo cya biti ya emulisile muri asfalt kizaba kinini kandi kinini. Ingano yo gukoresha nayo izaguka kandi yaguke, kandi ubuziranenge buzabe bwiza kandi bwiza. Bitumen emulisifike ifite ibiranga uburozi, impumuro nziza, idacana, gukama vuba no guhuza bikomeye. Ntishobora gusa kunoza ireme ryumuhanda, kwagura aho ikoreshwa rya asfalt, kongera igihe cyubwubatsi, kugabanya umwanda w’ibidukikije no kuzamura imiterere yubwubatsi, ariko kandi izigama ingufu nibikoresho.
Bitumen emulisile igizwe ahanini na bitumen, emulifier, stabilisateur namazi.
1. Bitumen nibikoresho byingenzi bya emulisile bitumen. Ubwiza bwa asfalt bufitanye isano itaziguye n'imikorere ya asfalt.
2. Emulsifier ni ikintu cyingenzi mugukora asfalt ya emulisile, igena ubwiza bwa asfalt.
3. Stabilisateur irashobora gutuma asfalt ya emulisile igira ububiko bwiza mugihe cyo kubaka.
4. Mubisanzwe birasabwa ko ubwiza bwamazi butagomba gukomera kandi ntibugomba kubamo indi myanda. Agaciro pH k'amazi na calcium na magnesium plasma bigira ingaruka kuri emulisifike.
Ukurikije ibikoresho na emulisiferi zikoreshwa, imikorere no gukoresha emulisifike ya asifalt nayo iratandukanye. Ibikoreshwa cyane ni: asifalt isanzwe ya emulisifike, SBS yahinduye emulisifike ya asifalt, SBR yahinduye emulisifike ya asifalt, iyindi buhoro buhoro guturika emulisifike ya asifalt, ubwinshi bwimikorere ya emulisifike, kwibanda cyane hejuru ya asfalt. Mu kubaka no gufata neza kaburimbo ya asfalt, asfalt ikwiye irashobora gutorwa ukurikije uko umuhanda umeze.
