Mbere ya byose, gutoranya pompe yo kugemura muri sitasiyo ivanze ya asfalt bigomba kuba byujuje ibisabwa byigihe kinini cyo gusuka asfalt mugihe cyubwubatsi, uburebure burebure, nintera nini itambitse. Muri icyo gihe, hagomba kubaho umubare munini wububiko bwa tekiniki n’umusaruro, kandi umusaruro uringaniye nibyiza inshuro 1,2 kugeza 1.5.

Icya kabiri, sisitemu ebyiri zingenzi zavanze na asfalt, kugenda na hydraulics, bigomba kuba bisanzwe, kandi ntihakagombye kubaho amajwi adasanzwe no kunyeganyega kugirango wirinde ibintu byinshi hamwe nibibyimba imbere mubikoresho, bitabaye ibyo biroroshye kwizirika ku biryo icyambu cyo kuvanga sitasiyo cyangwa guhagarikwa kubera arching. Indi ngingo ni uko iyo sitasiyo ivanze ya asfalt iri murubuga rumwe, ntibikwiye gukoresha pompe nyinshi na pompe biva mubakora inganda nyinshi kugirango birinde kugira ingaruka mubikorwa bisanzwe.
