Amavuta yo gutwika ikoreshwa mugihe igihingwa cyo kuvanga Asfalt gikora, ariko amavuta yo gutwika agabanijwe mumanota atandukanye. Gukoresha neza nurufunguzo rwo gusobanukirwa. Ibikurikira nibisobanuro byo gukoresha amavuta yo gutwika mu bimera bya Asfalt, nyamuneka wemeze kubahiriza.

Nk'uko amanota atandukanye ya virusire, amavuta yo gutwika arashobora kugabanywamo amavuta yoroheje n'amavuta aremereye. Amavuta yoroheje arashobora kubona ingaruka nziza zitoza nta gushyushya, mugihe amavuta aremereye agomba gushyuha mbere yo gukoreshwa kugirango amenye neza ko uruzitiro rwayo ruhuye nurwego rwemewe rwibikoresho. Ntabwo ari ikintu gikwiye gusa mumavuta gusa, ariko igikoresho kigomba no gusuzumwa, cyahinduwe kandi kisukura kugirango wirinde umuriro n'amavuta.
Byongeye kandi, imirimo irangiye, gutwika gutwikwa bigomba kuzimwa mbere, hanyuma gushyushya peteroli biremereye bigomba kuzimwa. Niba ari ngombwa guhagarika igihe kirekire cyangwa mugihe hakonje, valve yumuzunguruko igomba guhinduka hamwe numuzunguruko wa peteroli ugomba gusukurwa namavuta yoroheje, bitangira gutwikwa n'amavuta yoroheje, bitameze neza kubikorwa byigihingwa cya Asfalt.
