Ngomhla we-14 kaMeyi, izifundo ezibini, "Ukuthelekiswa koLwakhiwo lwekhoyili olungangenwa ngamanzi" kunye "noPhuhliso oluQhelekileyo lwamaqela e-asphalt angenamanzi", lwenziwa ngokukhawuleza kwisityalo sokuqala sokulinga i-asphalt esingenamanzi sasePetroChina.Ezi zizifundo ezimbini zokuqala eziqaliswe emva kokuba isiseko satyhilwa ngo-Epreli 29.

Njengoko iChina Petroleum isiseko sokuqala sovavanyo lokuvavanya i-asphalt engenamanzi, iziko lophando lwenkampani yeoli ye-oyile kunye ne-Jianguo Weiye Group kunye nezinye iiyunithi ziya kuzibophelela ekukhuthazeni nasekusetyenzisweni kwemveliso ye-asphalt emitsha engenamanzi, uphuhliso lwentsebenziswano ye-asphalt entsha engenamanzi kunye neemveliso ezincedisayo ezinxulumeneyo, kunye nokuphuhliswa kobuchwepheshe kwesi siseko soqeqesho loTshintsho, ukwenza umsebenzi wophando kwi-industry yemveliso yeemveliso ze-asphalt ezingenamanzi.Iza kuba sisiseko sokufukamela ukuguqulwa kweemveliso ezintsha kunye nobuchwepheshe obutsha bePetroChina, ebaluleke kakhulu ukukhawulezisa ukukhuthaza kunye nokusetyenziswa kweemveliso ze-asphalt ezingenamanzi zePetroChina kunye nokubonelela ngeemveliso ze-asphalt ezingcono nezinoqoqosho ngakumbi kushishino olungangeni manzi.

Njengemveliso ephezulu kwintsapho ye-asphalt, i-asphalt engenamanzi iye yaba yintlobo enkulu ye-asphalt ngaphandle kwe-asphalt yendlela.Kunyaka ophelileyo, i-petroleum yaseChina yokuthengiswa kwe-asphalt engenamanzi yafikelela kwi-1.53 ​​yezigidi zeetoni, kunye nesabelo semarike esingaphezulu kwe-21%.
