I-asphalt yokusabalalisa i-quota q (L/㎡) iyahluka kunye nento yokwakha, kwaye uluhlu lwayo lulandelayo:
1. Indlela yokungena ekusasazeni, 2.0 ~ 7.0 L/㎡
2. Ukusasazeka konyango lomphezulu, 0.75 ~ 2.5 L/㎡
3. Ukuthintela uthuli ukusasazeka, 0.8 ~ 1.5 L /㎡
4. Izinto eziphantsi zokudibanisa ukusabalalisa, i-10 ~ 15 L /㎡.

I-asphalt yokusabalalisa i-quota ichazwe kwiinkcukacha zobugcisa bokwakha.
Umyinge wokuhamba Q (L/㎡) wempompo ye-asphalt iyatshintsha ngesantya sayo. Ubudlelwane bayo kunye nesantya sesithuthi V, ububanzi obusasaza b, kunye nokusabalalisa isixa q: Q=bvq. Ngokuqhelekileyo, ububanzi obusasazekayo kunye nexabiso lokusabalalisa linikezelwa kwangaphambili.
Ngoko ke, isantya sesithuthi kunye nokuhamba kwepompo ye-asphalt zizinto ezimbini eziguquguqukayo, kwaye ezimbini zinyuka okanye ziyancipha ngokulinganayo. Kwi-asphalt ye-asphalt ene-injini ekhethekileyo eqhuba impompo ye-asphalt, isantya sempompo ye-asphalt kunye nesantya semoto sinokubakho.
zihlengahlengiswe ziinjini zazo, ngoko ukonyuka okuhambelanayo kunye nokuncipha kobudlelwane phakathi kwezi zibini kunokulungelelaniswa ngcono. Kubasasaza be-asphalt abasebenzisa i-injini yemoto ukuqhuba impompo ye-asphalt, kunzima ukuhlengahlengisa
Ukonyuka okuhambelanayo kunye nokuncipha kobudlelwane phakathi kwesantya semoto kunye nesantya sempompo ye-asphalt kuba indawo yegiya yebhokisi yemoto kunye nokuthathwa kwamandla kukhawulelwe, kwaye isantya sempompo ye-asphalt sitshintsha ngesantya semoto.
injini enye. Ngokuqhelekileyo, ixabiso lokuhamba kwempompo ye-asphalt kwisantya esithile sinqunywe kuqala, kwaye emva koko isantya sesithuthi esihambelanayo sihlengahlengiswa, kwaye isixhobo esinamavili amahlanu kunye nokusebenza kwezakhono zomqhubi kusetyenziselwa ukulwela ukuqhuba ngokuzinzile.
