Ikigaragara cyane ni ibicuruzwa bidahungabana hamwe nubushobozi buke bwibikoresho. Nyuma yisesengura, birazwi ko impamvu nyamukuru zubu bwoko bwo kunanirwa ari izi zikurikira:
1. Umubare udakwiye wibikoresho fatizo;
2. Ubwiza butujuje ubuziranenge bwibikoresho fatizo;
3. Agaciro gake ka peteroli mu bikoresho;
4. Igenamiterere ridakwiriye ryibikoresho bikora.
Nyuma yo kumenya impamvu niyo mpamvu, fata ibisubizo bihuye.
Usibye gukora neza, ubushyuhe bwo gusohora uruganda ruvanze na asfalt rimwe na rimwe rudahinduka kandi ntirushobora kuzuza ubushyuhe bukabije busabwa. Igitera iki kibazo nukugenzura ubushyuhe butari bwo, kandi ingano yumuriro ugurumana igomba guhindurwa kugirango iki kibazo gikosorwe.
