Bhitumini matangi "yemukati kudziyisa mhando munharaunda nokukurumidza bhitumini okuchengetera hita zvishandiso". Iyi nhevedzano parizvino ndiyo yakanyanya kusimira asphalt midziyo muChina iyo inobatanidza kupisa nekukurumidza, kuchengetedza simba uye kuchengetedza kwezvakatipoteredza. Iyo yakananga kupisa inotakurika midziyo muchigadzirwa haina kungoita kukurumidza kupisa kumhanya, inochengetedza mafuta, asiwo haisvibise zvakatipoteredza, uye iri nyore kushanda.

Iyo inoshanda preheating system inobvisa zvachose dambudziko rekubheka kana kuchenesa bhitumini nemapaipi. Iyo inoshanda yekutenderera maitiro inobvumira bhitumini kuti ipinde otomatiki mu hita, muunganidzi weguruva, induced draft fan, bhitumini pombi, uye bhitumini tembiricha kuratidza sezvinodiwa.
Iyo ine chiratidziro chemvura, gwenya jenareta, pombi uye bhitumini pombi preheating system, inodzvinyirira system, sitimu yekupisa, tangi yekuchenesa system, uye tangi yekuburitsa mafuta. Ese akaiswa pane tangi muviri (mukati) kugadzira compact yakabatanidzwa chimiro.
Hunhu hwebhitumini matangi ndeichi: kudziya nekukurumidza, kuchengetedza simba, hukuru hwekugadzira, hapana tsvina, hapana kuchembera, kushanda kuri nyore, zvese zvishongedzo zviri pamuviri wetangi, uye zvinonyanya nyore kufamba, kusimudza, uye kuchengetedza. Rudzi rwakagadziriswa rwakanyanya nyore.
