Dhizaini yehurongwa hwekutonga, iyo yakakosha chikamu cheasphalt kusanganisa chirimwa, yakaunzwa kwauri. Zviviri zvinotevera ndezvekuchengetedza kwayo kwezuva nezuva. Usafuratira chikamu ichi. Kuchengetedza kwakanaka kuchabatsirawo hurongwa hwekutonga kuita basa rayo, nekudaro kukurudzira kushandiswa kweasphalt kusanganisa chirimwa.

Kufanana nemimwe michina, iyo asphalt inosanganisa chirimwa chekutonga system inofanirwawo kuchengetedzwa mazuva ese. Izvo zvekuchengetedza zvemukati zvinonyanya zvinosanganisira kuburitswa kwemvura yakapfupikiswa, kuongororwa kwemafuta ekuzora uye manejimendi nekuchengetedza iyo air compressor system.
Sezvo kubuda kwemvura yakanyungudutswa kunosanganisira iyo yose pneumatic system, zvinodikanwa kudzivirira madonhwe emvura kupinda muzvikamu zvekutonga. Kana iyo pneumatic mudziyo iri kushanda, tarisa kuti mafuta ekudonhedza yababa oiri anosangana nezvinodiwa uye kuti ruvara rweoiri rwakakwana here. Usasanganisa tsvina yakaita seguruva nehunyoro mairi. Kutarisirwa kwemazuva ese kweiyo air compressor system haisi chinhu kunze kwekunzwika, tembiricha uye mafuta ekuzora, nezvimwewo, kuve nechokwadi kuti izvi hazvipfuuri zviyero zvakatarwa.
