Paunenge uchitenga simiti yekusanganisa asphalt, vashandi vehunyanzvi hwemugadziri vakaita zviyeuchidzo zvakakosha pamusoro pezvinodiwa zvekuzora zvemidziyo, kusanganisira mafuta echikamu chimwe nechimwe, chisingagoni kuregererwa. Panyaya iyi, vashandisi vakagadzirawo mitemo yakasimba yekuvatonga, sezvinotevera:
Chekutanga pane zvese, yakakodzera mafuta ekuzora anofanirwa kuwedzerwa nguva nenguva kune chimwe nechimwe chikamu muasphalt kusanganisa zvirimwa; maererano nehuwandu hwemafuta ekuzora, inofanira kuchengetwa yakazara. Oiri yemafuta mudziva remafuta inofanira kusvika pachiyero chemvura inotsanangurwa nechiyero, uye haifaniri kunge yakanyanyisa kana kuti shoma. Kana zvisina kudaro, zvichakanganisa kushanda kwezvikamu; maererano nemhando yemafuta, inofanirwa kuve yakachena uye haifanirwe kusanganiswa netsvina senge tsvina, guruva, machipisi, uye mwando kudzivirira kukuvadzwa kwezvikamu zveasphalt kusanganisa chiteshi nekuda kwekusagadzikana kwemafuta.
Chechipiri, mafuta ekuzora mutangi anofanira kutsiviwa nguva nenguva, uye tangi inofanira kucheneswa risati ratsiviwa kudzivirira kusvibiswa kwemafuta matsva. Kuti usakanganiswa nezvinhu zvekunze, midziyo yakaita sematangi emafuta inofanira kuvharwa zvakanaka kuitira kuti tsvina isapinde.
