1. Uburebure: Uburebure bwumusumari wo hejuru wahisemo bizaterwa nubunini bwibikoresho byo hejuru ukoresha, hamwe nubujyakuzimu bwigisenge.Imisumari migufi ikoreshwa mubikoresho byoroheje nka shitingi ya asfalt, mugihe imisumari miremire ikenerwa kubikoresho binini nko kunyeganyeza ibiti cyangwa ikibaho.
2. Ubwoko bwumutwe: Inzara zo hejuru ziza muburyo butandukanye bwumutwe, harimo imitwe isanzwe, imitwe minini, hamwe n imisumari.Ubwoko bwumutwe wahisemo bizaterwa nubwoko bwibisenge ukoresha nurwego wifuza rwo gufata imbaraga.Umutwe munini, kurugero, urashobora gukenerwa kubikoresho bikunda kunyerera cyangwa guhinduka.
3. Ubwoko bwa Shank: Imisumari yo hejuru nayo iza muburyo butandukanye bwa shanki, harimo imisumari ya shank yoroshye kubikoresho byoroheje hamwe n imisumari ya ring-shank kubikoresho bikomeye nkibiti.Imisumari ya ring-shank yashyizeho impande zibafasha gufata ibikoresho neza, bikagabanya ibyago byo gukuramo imisumari cyangwa guhinduranya ibintu.
4. Galvanisation: Imisumari yo hejuru yo gusakara yubatswe hamwe na zinc, ifasha mukurinda ingese no kwangirika.Ibi ni ingenzi cyane kubisenge ahantu hafite ubushyuhe bwinshi cyangwa imvura ikunze kugwa, kuko ishobora kwagura cyane igihe cyimisumari.
Mu gusoza, imisumari yo gusakara igira uruhare runini mugukora ibishoboka byose kugirango ibisenge bifatwe neza ku gisenge cy’inzu, birinda inyubako ibintu kandi bikomeza kubaka igisenge gikomeye kandi gihamye.Mugihe uhitamo imisumari yo hejuru, nibyingenzi gusuzuma ibintu nkuburebure, ubwoko bwumutwe, ubwoko bwa shank, hamwe na galvanisation kugirango umenye neza ko uhitamo ubwoko bukwiye kumushinga wawe wihariye.Hamwe nimisumari ibereye yo gusakara, urashobora kwemeza ko umushinga wawe wo gusakara uzagenda neza, hamwe nigisenge gifite umutekano, gihamye, kandi cyubatswe kuramba.
