Kugeza ubu, uruganda rwa bitumen rutagira umwanda rukoreshwa mu bisate bya beto hamwe na asfalt, asfalt na epoxy resin beto muri rusange. Icyo abantu bakunze guhangayikishwa nuburyo bwo kugabanya ikibazo cyibice byerekana ibyatsi bitumen bitumen decanter nyuma yo kubitsa. Kubijyanye niki kibazo, twizera ko uburambe bwimibereho yimishinga myinshi yubwubatsi ku isi bwerekana ko byanze bikunze ibice byimyanda bitumen bitumen bitagira ingese byanze bikunze. Nubwo ingamba zo gukumira zafatwa gute kugirango ikibazo gikemuke, ibice by'imyenda ya bitumen bitagira umwanda bizaterwa vuba cyangwa vuba.

Icya kabiri, nyuma yo gutobora ibyuma bitagira umwanda bitumen biterwa ninganda, niba bibungabunzwe neza kuburyo bitakomeje gutera imbere no guteza izindi ndwara, ntabwo bizangiza byinshi mubikorwa byubuso bwumuhanda; mubyukuri, imyaka myinshi yubushakashatsi bwerekanye ko kubintu bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito bito, Kubwibyo, gukumira ibice byerekana nikibazo nyamukuru cya beto.
Ibikoresho fatizo byuruganda rwa bitumen bitagira umuyonga ni ifu ya simaitima ya sima itagira ingufu zinjira mu kirere, kandi icyambere cyibanze mugushushanya ibyuma bitagira umwanda bitumen kumihanda ya beto ni rusange. Ntabwo ari ngombwa kugabanya ibice byerekana nkikimenyetso cyingenzi cyerekana igishushanyo mbonera cyubwubatsi bwa elastique, kandi ntabwo ari ngombwa kongera umubyimba w’uruganda rwa bitumen ibyuma bitagira umwanda cyane kugirango ugabanye ibice byerekana. Birumvikana ko ibyo bidasobanura byanze bikunze ko bidakenewe gufatanwa uburemere. Gushyira umwenda winyuma wurukuta hejuru ya beto no gukwirakwiza asifalt yubutaka butarinda amazi bizafasha kunoza imiterere yimiterere ya kaburimbo no kugabanya ibitera.
Igishushanyo mbonera cyo kongeramo ibyuma bitumen bitumen decanter bigomba kuba nkibisanzwe muri rusange bitumen bitumen. Hashingiwe ku gusuzuma ubushobozi bwo gutwara, ibihingwa bitangiza ibyuma bitumen bitumen bigomba kuzirikana ibisabwa kugirango imikorere ikorwe, kandi imiterere yumuhanda igomba kugira amazi meza hamwe nubushyuhe bukabije. Byongeye kandi, urebye imiterere yo kuvugurura umuhanda wa beto, hagomba kubaho kumva kubaka ibice. Umubyimba wibyuma bidafite ingese bivana nibisabwa mubikorwa byogukoresha, nubwo iyi myumvire idahuye nicyerekezo. Ibyuma binini cyane bitagira ibyuma bitumen decanter bidafite akamaro kanini mugutezimbere ingaruka ziteganijwe zo gukoresha umuhanda. Kugeza ubu, birasa nkaho imiterere yinzego ebyiri ari nziza kandi ni iterambere rya societe nubukungu mu kuvugurura imihanda ishaje.
