Ni ngombwa kandi kubungabunga buri munsi no kwita ku bimera bivangwa na asfalt. Umukungugu munini uzabyara mugihe cyo gukora ibikoresho. Niba iyi mukungugu iguye mubice byingenzi byibikoresho, bizagira ingaruka kumikorere isanzwe yibikoresho. Ibikoresho bizaba munsi yumutwaro mwinshi iyo biri munsi yubushyuhe bwo hejuru kandi bikomeza gukora igihe kirekire. Niyo mpamvu, birakenewe gusiga buri gihe ibikoresho, kugenzura ecran yinyeganyeza, umuyoboro wa gazi, umuyoboro ugaburira, nibindi, ndetse no gusukura icyumba cyabigenewe no gusukura umuryango usohoka. Ibi birashobora kwemeza imikorere isanzwe yibikoresho, kuzamura ubwiza bwivanga rya asfalt, no kongera igihe cyibikorwa byibikoresho.

Hamwe niterambere ridahwema kubaka umuhanda wo murwego rwohejuru, tekinoroji yo guteranya no gushiraho ibikoresho binini byo kuvanga asifalt nini nayo igenda itera imbere buhoro buhoro. Kugirango ushyireho ibiti binini bivangwa na asfalt, birakenewe kwitondera guhitamo ikibanza hamwe nubuhanga bukoreshwa, no kumenya uburyo bwo gushiraho umusingi nibikoresho. Muri icyo gihe, hamwe n’imihindagurikire yuburyo bwo kubaka umuhanda, birakenewe kandi ko hajyaho ibikoresho byumusaruro bigezweho ukurikije ibisabwa byiterambere ryibihe, nkibikoresho bivanga asifalti rimwe na rimwe, bifite ibiranga imikorere yoroshye nakazi gakomeye gukora neza.
Muri rusange, nk'ibikoresho remezo by'ingenzi, inganda zivanga asifalt zigira uruhare runini mu kubaka umuhanda. Binyuze mu gushyira mu gaciro, gucunga umutekano no kubungabunga buri munsi, turashobora gukora neza kandi neza, tugatanga inkunga ikomeye mu iyubakwa ry’igihugu cyanjye.
