Bitewe ningaruka zimpamvu zitandukanye, kuvanga ibihingwa bya asfalt byanze bikunze bizagira ibibazo nyuma yigihe cyo gukoresha. Kubera kubura uburambe, ntibazi gukemura ibyo bibazo. Muhinduzi avuga muri make uburambe nubuhanga muriki kibazo kugirango ubone.

Ukurikije uburyo butandukanye bwikibazo cyikivange cya asfalt, igisubizo nacyo kiratandukanye. Kurugero, mugihe ibice biri muruganda rwa asfalt bivanze numunaniro byangiritse, birakenewe gutangirira kumusaruro wibice. Ku ruhande rumwe, birakenewe kunoza ubuso burangije ibice. Ku rundi ruhande, intego yo kugabanya imihangayiko yibice bishobora kugerwaho hifashishijwe uburyo bworoshye bwambukiranya ibice. Byongeye kandi, imikorere yibice irashobora kunozwa no gutwika, kuzimya nubundi buryo, kugirango ugere ku ngaruka zo kugabanya umunaniro w’ibice.
Ariko niba ibyangiritse byibice bivangwa na asfalt biterwa no guterana amagambo, hakwiye gukorwa iki? Inzira yoroshye kandi yingirakamaro ni ugukoresha ibikoresho birwanya kwambara bishoboka, kandi mugihe ushushanya imiterere yibigize ibimera bivanga, gerageza kugabanya ubukana bwayo. Byongeye kandi, ruswa nayo ni imwe mu mpamvu zitera kwangirika kw'ibice. Muri iki gihe, urashobora gukoresha nikel, chromium, zinc nibindi bikoresho birwanya ruswa kugirango ushire hejuru yicyuma, cyangwa ugashyiraho amavuta hejuru yibice byicyuma, hanyuma ugashyiraho irangi rirwanya ruswa hejuru yibice bitari ibyuma. kugirango wirinde ibice kwangirika.
