Ngomhla we-14 kaMeyi, izifundo ezibini, "Ukuthelekiswa koBume beKhoyili obungangenwa ngamanzi" kunye "noPhuhliso oluQhelekileyo lwamaqela e-asphalt angenamanzi", lwenziwa ngokukhawuleza kwisityalo sokuqala sokulinga i-asphalt esingenamanzi sasePetroChina. Ezi zizifundo ezibini zokuqala eziqaliswe emva kokuba isiseko satyhilwa nge-29 ka-Epreli.

Njengoko iChina Petroleum isiseko sokuqala sovavanyo lovavanyo lwe-asphalt engangeni manzi, iziko lophando lenkampani yeoli ye-oyile kunye neJianguo Weiye Iqela kunye nezinye iiyunithi ziya kuzibophelela ekukhuthazeni nasekusetyenzisweni kweemveliso ezintsha ze-asphalt ezingenamanzi, uphuhliso lwentsebenziswano ye-asphalt entsha engenamanzi kunye neemveliso ezincedisayo ezinxulumene noko, kunye nophuhliso. yobugcisa kwesi siseko Uqeqesho Utshintshiselwano, enze umsebenzi wophando kwi-imveliso yoshishino iimveliso asphalt amanzi. 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%.
