Ndabaza niba wabonye ko urufunguzo rwo guhitamo ibikoresho byo kuvanga Ashalt biri mubyemezo byubwoko bwabwo. Usibye gusuzuma imiterere yo kuvanga, ibintu bigira uruhare runini. Nibihe bisabwa ibikoresho byo kuvanga Asfalt byateguwe ukurikije?

Hariho ibintu byinshi bigomba gusuzumwa, ntabwo ari ukuzenguruka imisozi gusa; guhuza n'imihindagurikire y'urugero kugeza ku rugero rw'ibikoresho; Imiterere y'urugendo ikozwe n'umufasha, n'ibindi, ariko kandi ibiranga abacamanza batandukanye bakeneye guhuzwa n'imigambi itandukanye. Reka tuganire ku kibazo cyo gutoranya.
Byongeye kandi, ibyingenzi byo guhitamo icyitegererezo ntabwo ari icyemezo cyo kugena ubwoko, gusa ahubwo no mubikoresho nyuma yo kugena ubwoko. Kurugero, ibyuma bya karubone, ibyuma bidafite ishingiro, umurongo wikirahure, nibindi birashobora gutoranywa, muri rusange ukurikije imikorere yibikoresho bivanze. Menya ibizava muriyi ngingo.
