Muburyo bwo gutegura ibikoresho byahinduwe bitumen, kugenzura ubushyuhe ni ngombwa cyane. Niba ubushyuhe bwa bitumen buri hasi cyane, bitumen izaba ndende, idafite amazi make, kandi bigoye kwigana; niba ubushyuhe bwa bitumen buri hejuru cyane, kuruhande rumwe, bizatera bitumen gusaza. Muri icyo gihe, ubushyuhe bwinjira n’isohoka rya biti ya emulisile bizaba hejuru cyane, bizagira ingaruka ku ituze rya emulisiferi ndetse n’ubuziranenge bwa biti ya emulisile. Icyo buri wese agomba kumva kandi ni uko bitumen ari ikintu cyingenzi cya emulisile bitumen, muri rusange ikaba igizwe na 50% -65% yubuziranenge bwa bitumen.
Iyo biti ya emulisile yatewe cyangwa ivanze, bitum ya emulisile irasibangana, hanyuma amazi arimo arimo akayuka, igisigaye hasi rwose ni bitumen. Kubwibyo, gutegura bitumen ni ngombwa cyane. Byongeye kandi, buriwese agomba kumenya ko mugihe uruganda rwa bitumen emulisile rwakozwe, ubwiza bwa bitumen buragabanuka uko ubushyuhe bwiyongera. Kuri buri 12 ° C kwiyongera, ubukonje bwacyo bugira hafi kabiri.
Mugihe cyo gutanga umusaruro, bitumen yo guhinga igomba kubanza gushyukwa mumazi mbere yuko emulisation ishobora gukorwa. Kugirango uhuze nubushobozi bwa emulisiyonike ya micronizer, ubukonje bwingirakamaro bwibihingwa fatizo bitumen muri rusange bigenzurwa nka 200 cst. Hasi yubushyuhe, niko hejuru yubukonje, pompe ya bitumen rero igomba kuzamurwa. n'umuvuduko wa micronizer, ntishobora kwigana; ariko kurundi ruhande, kugirango twirinde guhumeka no guhumeka amazi menshi mubicuruzwa byarangiye mugihe cyo gukora bitumen emulisile, bizaganisha ku gusenya, kandi biragoye no gushyushya ibihingwa bito bito cyane, micronizer ikoreshwa muri rusange. Ubushyuhe bwibicuruzwa byarangiye ku bwinjiriro no gusohoka bigomba kuba munsi ya 85 ° C.
