Ibhitumene lulwelo olumnyama nolubonakala kakhulu okanye uhlobo oluqinileyo lwepetroleum. Inokufumaneka kwiidiphozithi zendalo zamaminerali. Ukusetyenziswa okuphambili kwe-asphalt (70%) kulwakhiwo lwendlela, njenge-binder okanye i-adhesive ye-asphalt concrete. Olunye usetyenziso lwayo oluphambili lukwimveliso ye-asphalt yokuthintela amanzi, kubandakanywa ukufulela izinto zokuqinisekisa ukufuma ukutywina uphahla olusicaba.

Inkqubo yokuvelisa i-asphalt yokuxuba iquka ukuxuba i-granite aggregates kunye ne-asphalt ukufumana umxube we-asphalt. Umxube obangelwayo usetyenziswa ngokubanzi njengento yokulungisa indlela. Uninzi lwamandla enkqubo lusetyenziselwa ukomisa kunye nokufudumeza i-aggregates. Ngoku iSinoroader Group inikezela ngesizukulwana esitsha sezityalo zokuxuba i-asphalt ezihlangabezana nazo zonke iimfuno zanamhlanje zokuhambelana kwendalo, ukuthembeka kokusebenza, ukuvelisa umgangatho we-asphalt. Umgaqo-nkqubo womgangatho yenye yeengongoma eziphambili zeshishini.
I-Sinoroader Group isebenzisa ubuchwepheshe obutsha kunye nezakhiwo ze-methodological, iphendule ngokuguquguqukayo kwiimfuno zabathengi, iimfuno ezenza kube lula ukuvelisa iimveliso ezikumgangatho ophezulu kunye nokuhlangabezana ngokupheleleyo neemfuno zabathengi: ukuthengisa izixhobo ngexabiso elipheleleyo, iinxalenye zangaphambili kunye nezinto ezidliwayo, ukwenza indibano, ukugunyazisa kunye nokuhlangabezana ngokupheleleyo neemfuno zabathengi. ukufumanisa isiphene, ukwenza iwaranti, ukwenza iplanti yemveliso ibe yeyanamhlanje kunye noqeqesho kwiminyaka edlulileyo.
