Amavuta yo gutwika akoreshwa mugihe uruganda ruvanga asfalt rukora, ariko amavuta yo gutwika agabanijwe mubyiciro bitandukanye. Gukoresha neza nurufunguzo rwo gusobanukirwa. Ibikurikira nibisobanuro byo gukoresha amavuta yaka mumashanyarazi avanze na asfalt, nyamuneka wemeze kubyubahiriza.

Ukurikije ibyiciro bitandukanye bya viscosity, amavuta yaka ashobora kugabanywamo amavuta yoroheje namavuta aremereye. Amavuta yoroheje arashobora kubona ingaruka nziza za atomisiyasi adashyushye, mugihe amavuta aremereye agomba gushyuha mbere yo kuyakoresha kugirango yizere ko ububobere bwayo bujuje ibikoresho byemewe. Ntabwo bikwiye kuranga gusa amavuta, ariko igikoresho nacyo kigomba kugenzurwa, guhindurwa no gusukurwa kugirango birinde umuriro n’amavuta.
Byongeye kandi, nyuma yakazi karangiye, icyotezo kigomba kubanza kuzimwa, hanyuma gushyushya amavuta aremereye bigomba kuzimwa. Niba ari ngombwa kuzimya igihe kirekire cyangwa mugihe hakonje, valve yumuzunguruko wamavuta igomba guhindurwa kandi umuzenguruko wamavuta ugomba guhanagurwa namavuta yoroheje, bitabaye ibyo bizatuma uruziga rwamavuta ruhagarikwa cyangwa bigoye gutwikwa, bikaba bidakwiye cyane imikorere yikimera cyose kivanga asfalt.
