Nekusimudzira nzanga uye nekukasira kukura kwehupfumi hwenyika yedu, zvivakwa zvemumba zviri kukura nekukurumidza uye nekukurumidza. Hazvina maturo kutaura, kushandiswa kwemusika kweasphalt kusanganisa zvidyarwa zviri kuwedzerawo zvishoma nezvishoma. Vazhinji vashandisi nevagadziri vanoona mukana wemusika muindasitiri iyi. Watoiswa mari. Naizvozvo, mukuita uku, kusarudzwa kwenzvimbo yekuvaka kwakakosha zvikuru. Nzvimbo yeasphalt mixing plant yakabatana zvakananga nekushanda kwayo kwenguva refu.

Kazhinji kutaura, pane zvinhu zvitatu zvakakosha zvekusarudza nzvimbo yakakodzera yekuvaka yeasphalt yekusanganisa chirimwa. Chimiro ndechekuti mushandisi anofanirwa kujairana nemafambisirwo enzvimbo yekuvaka. Sezvo kureba kwekufambisa kweasphalt mbishi kunokanganisa zvakananga kunaka kweasphalt, pakusarudza kongiri asphalt, kero yechiteshi chekusanganisa inofanirwa kutariswa zvizere kuti isangane nezvinodiwa zvesaiti zvizere sezvinobvira. Mugadziri wacho anodawo kusimbisa kugoverwa kweasphalt zvichienderana nemifananidzo yekuvaka kuitira kuti inenge yepakati peiyo asphalt yekusanganisa michina inowanikwa.
Chechipiri chechipiri ndechekuti vagadziri vanofanirwa kugona uye kunzwisisa zvinhu zvakakosha zveasphalt kusanganisa michina, senge mvura, magetsi uye pasi nzvimbo inodiwa panguva yekushanda kweasphalt kusanganisa michina.
Rutivi rwokupedzisira rwokupa ngwariro kwarwo inzvimbo yakapoteredza nzvimbo yokuvaka. Iyo asphalt yekusanganisa chiteshi inzvimbo yekugadzirisa ine yakakwira dhigirii yemagetsi, saka guruva, ruzha uye kumwe kusvibiswa kunogadzirwa panguva yekugadziriswa kuchave kwakanyanya. Nokudaro, pakusarudza nzvimbo yekuvaka, zvikoro nemapoka ekugara zvinofanira kudziviswa sezvinobvira. Deredza kukanganisa pane zvakatipoteredza.
