Ngomhla ziyi-14 kuNhlaba, izifundo ezimbili, “Ukuqhathaniswa Kokwakhiwa Kwekhoyili Engangeni Manzi” kanye “Nokuthuthukiswa Okujwayelekile Kwamaqembu Etiyela Angangeni Manzi”, zenziwa ngokugcwele embonini yokuqala yokuhlola i-asphalt engangeni manzi yasePetroChina. Lezi yizifundo ezimbili zokuqala ezethulwe ngemuva kokwembulwa kwesisekelo ngo-Ephreli 29.

Njengesisekelo sokuqala sokuhlola umshayeli wetiyela elingangeni manzi eChina Petroleum, isikhungo socwaningo senkampani kawoyela kawoyela kanye neJianguo Weiye Group namanye amayunithi azozibophezela ekukhuthazeni nasekusetshenzisweni kwemikhiqizo emisha yetiyela engangeni manzi, ukuthuthukiswa ngokubambisana kwetiyela elingangeni manzi nemikhiqizo ehlobene nayo, kanye nentuthuko. yobuchwepheshe kulesi sisekelo sokuqeqeshwa kokushintshana, yenza umsebenzi wocwaningo ngokusetshenziswa kwezimboni kwemikhiqizo yetiyela engangeni manzi. Izoba isizinda sokufukamela sokuguqulwa kwemikhiqizo emisha kanye nobuchwepheshe obusha bePetroChina, okubaluleke kakhulu ukusheshisa ukukhuthazwa nokusetshenziswa kwemikhiqizo yetiyela engangeni manzi yePetroChina nokuhlinzeka ngemikhiqizo yetiyela engangeni manzi engcono neyongayo embonini engenamanzi.

Njengomkhiqizo osezingeni eliphezulu emndenini we-asphalt, i-asphalt engenamanzi isibe yizinhlobonhlobo ezinkulu ze-asphalt ngaphandle kwe-asphalt yomgwaqo. Ngonyaka odlule, ukuthengiswa kwe-asphalt ye-petroleum engangeni manzi eChina kwafinyelela amathani ayizigidi ezingu-1.53, nesabelo semakethe esingaphezu kwama-21%.
