Imyitozo yerekanye ko tekinoroji ya asfalt yatewe kashe ya tekinoroji ari ingamba zifatika zo gufata neza indwara z’imihanda hakiri kare no kwirinda amazi y’imihanda irimo kubakwa n’imihanda ivuguruye. Iri koranabuhanga rifite ubukungu, ryihuta, ridafite amazi, kandi rirashobora kuvura neza indwara hakiri kare ya asfalt. Ikoreshwa rya emulisifike ya asifalt ya kashe ikoresha neza ibiranga igifuniko cyiza, amazi meza, kwinjira cyane hamwe no gufatira hamwe ibikoresho bya asfalt byatewe na emulisile, bishobora gukiza umuhanda, kumeneka, kumeneka nizindi ndwara, kuzamura amazi, kurwanya skid hamwe no gutwara neza hejuru yumuhanda.

Hamwe nogukomeza kunoza kwagura umuhanda wigihugu hamwe nibisabwa hejuru yumuhanda, igihe cyo kubaka umuhanda no gufata neza kirageze! Kugirango turusheho kunoza uburyo bwo gufata neza umuhanda nubushobozi bwubwishingizi bwihutirwa, ingamba zo gukumira nko kubaka umuhanda no gufata micro-surfacing ni ngombwa cyane. Sinoroader slurry kashe yikinyabiziga nigicuruzwa cya chassis cyujuje ibyifuzo byisoko ryigihe cyo kubaka no kubungabunga. Ikoreshwa cyane cyane mu kubaka ibice bikora (hejuru ya kashe yo hejuru, kashe yo hepfo) ya paje ya asifalt yubatswe, kubaka ibyiciro bitandukanye bya kaburimbo ya asifalt (kashe ya kashe ya kashe, micro-surfacing) no gusana ibiti. Ikidodo cyoroshye gishobora kugira uruhare mu kwirinda amazi, kurwanya skid, gusibanganya, kutambara, no kugarura isura yumuhanda.
