Kugeza ubu, ibyuma bitugeraho bituba byakoreshejwe kubisate bifatika hamwe na asfalt, asfalt na epoxy resin bein betrete murwego rwo hejuru. Ibyo abantu mubisanzwe bahangayikishijwe nuburyo bwo kugabanya ikibazo cyo kwerekana ibishushanyo mbonera bya blal bitumen biteguye amacakubiri nyuma yo guhatanira. Ku bijyanye n'iki kibazo, twizera ko uburambe bw'imibereho y'imishinga myinshi yo kubaka hirya no hino byerekana ko ibice by'ibyuma bitumvikana bya bitumen byanze bikunze. Nubwo ingamba zo gukumira zifatwa kugirango zikemure ikibazo, ibice bya steel bitumer bitumer bitumen bizanwa vuba cyangwa nyuma.

Icya kabiri, nyuma yo gucamo amabuye yicyuma bitagira ingano byatewe, niba babungabunzwe neza kuburyo bataratera imbere kandi bateje izindi ndwara, ntabwo bizatera ibyangiritse cyane mubikorwa byumuhanda; Mubyukuri, imyaka myinshi yubushakashatsi yerekanye ko kubwinyungu zabatanduye gato yatumen, impamvu nyamukuru itera imidugararo yubushyuhe, ntabwo ari uguturika cyangwa ibice bihuye. Kubwibyo, kubuza ibice byerekana ni ikibazo nyamukuru cya beto.
Ibikoresho bibisi byo kubyuma byanduye bituba byanduye ni ibisumbo byifuzwa bihamye byinjira mu kirere, kandi ikintu cya mbere gishingiye ku gishushanyo cy'ibyuma bidafite ishingiro ku mihanda yatuze muri rusange. Ntabwo ari ngombwa kugabanya ibice byerekana imiterere yimishinga yingenzi yo kubaka burundu, kandi ntabwo ari ngombwa kongera ubunini bwa stoel bitumer bitumer bitumer bitumer bitum cyane kugirango bigabanye ibice byerekana. Birumvikana ko ibi bidasobanura ko byanze bikunze bidakenewe gufatanwa uburemere. Gushyira urukuta rwinyuma rwurukuta ruri hejuru kandi ukwirakwiza imphalt yubutaka bizafasha kunoza imiterere yimihangayiko ya kaburimbo yo murwego rwo hejuru no kugabanya icyateye.
Igishushanyo mbonera cyo kongeramo igihingwa cyanduye bituzanye karumen kigomba kuba kimwe nibishushanyo mbonera bya bitumer bidafite decanter. Munsi yibanze yo gusuzuma ubushobozi bwo kwitwaje, ibyuma bidatinze byanduza ibihingwa bigomba kuzirikana ibisabwa byimikorere isaba, kandi imiterere yumuhanda igomba kuba ifite umutekano wamazi nubushyuhe bwinshi buteye ubwoba. Byongeye kandi, urebye imiterere yo kuvugurura umuhanda, hagomba kubaho kumva ko ubwubatsi. Ubunini bwibyuma bitagira ingano yiyambura ingunguru biterwa nibisabwa imikorere ya porogaramu, nubwo iki gitekerezo kidahuye ninzira. Ibiti binini cyane bya stoel bitumen bitumen bitemewe kugirango biteze imbere ingaruka ziteganijwe zo gusaba umuhanda. Kugeza ubu, bisa nkaho imiterere yibiri ari nziza kandi ni iterambere rya societe nubukungu kugirango tuvugurure imihanda ishaje.
