Imihanda ya none na kaburimbo byarahindutse: ingano yumuhanda hamwe ninshuro zo gutwara abantu byiyongereye cyane, ni ukuvuga ibikorwa bya bitumen byahinduwe mubushyuhe bwo hejuru;
Kunoza ubwitonzi nubuka, ni ukuvuga ubushobozi bwo kurwanya guca ubushyuhe buke; Kunoza kwambara no kubaho kwa serivisi. Inyubako zigezweho zikoresha cyane-igihe kinini giterwa nicyuma cyicyuma, gisaba ibikoresho byamasoko yinyuma bigomba guhuzwa mubintu binini. Barashobora kandi kwihanganira imiterere yubushyuhe bwo hejuru kandi buke, bafite imikorere myiza, barifata, borohereza kubaka, no kugabanya imirimo yo kubungabunga.

Iyi mpinduka iterwa no gukoresha ibidukikije bitunguranye bitanga umusaruro ukomeye mubikorwa bya bitumen byahinduwe. Abantu bahinduye akamaro kanini kugirango bamenyeshejwe bitumen kugirango babamenyereye ibisabwa byavuzwe haruguru. Byahinduwe bitumen gutera ibikoresho bitarimo amazi hamwe ninkono yubwubatsi byerekana ahanini ingaruka zifatika mumishinga imwe yubuhanga.
Ariko, kubera ko igiciro cyibikoresho fatizo nyuma ya bitumen muri rusange ni inshuro 2 kugeza 7 kurenza ibya bitumer, hamwe nubunini bwa Bitumen bwiyongera buhoro buhoro. Uyu munsi bitumen yahinduwe cyane mugukoresha ahanini mu guhana ahantu hadasanzwe nk'imihanda miremire, imihanda ihebuje, ahantu hasukuye, ahantu h'imikino, amasangano n'imiryango iremereye. Muri kiriya gihe, byakoreshejwe beto ya bitumen byakoreshejwe mu kubungabunga no gushimangira imiyoboro yo mu muhanda, byateje imbere gukoresha cyane imihanda yahinduwe ya bitumen.
