Igihingwa cyo kuvanga Ashalt ni igice cyihariye cyo kwitegura asfalt, kirimo ibikoresho byinshi imbere, hamwe nuyungururagurika umukungugu nimwe murimwe. Kugirango wuzuze ibisabwa byivanga kuva ikanavanga, ni ibihe bintu bya tekiniki ikuramo ivumbi hano ifite?

Duhereye ku isonga ryayo, gukuraho umukungugu kuyungurura ibihingwa bya asfalt byemeza ikibazo kidasanzwe cyo kuyungurura ibintu, bifite imiterere yoroheje kandi bizigama umwanya; Kandi ifata igishushanyo mbonera cyubatswe, kidafite ikimenyetso cyiza gusa, ahubwo gishobora gushyirwaho byoroshye, kugabanya cyane igihe cya parikingi. Kuva mubikorwa byayo ingingo, umusego wo gukuraho umukungugu ufite imikorere minini. Gufata impuzandengo ugereranije na mikorobe 0.5 yifu nkurugero, imikorere ya filtration irashobora kugera kuri 99.99%.
Ntabwo aribyo gusa, gukoresha iyi filteri birashobora kandi kuzigama ibihuru bifatanye; Imiterere yo kwishyiriraho Silinderi yayunguruzo nayo izahinduka siyansi guhura nikibazo cyabakoresha.
