Ngokuqiniswa kwendlela yokukhuselwa kwendalo kunye nokugcinwa kwamandla, ukukhuselwa kokusingqongileyo kwezikhululo zokuxuba i-asphalt ngokuthe ngcembe ibe yindlela eqhelekileyo yophuhliso lwesikhululo sokuxuba. Loluphi uhlobo lwezixhobo ezinokubizwa ngokuba sisikhululo sokuxuba i-asphalt esisingqongileyo? Zeziphi iimeko ezisisiseko ekufuneka kuhlangatyezwane nazo?

Okokuqala, njengesikhululo sokuxuba i-asphalt yekhonkrithi ehambelana nokusingqongileyo, kufuneka ihlangabezane nemfuneko yokusebenzisa amandla amancinci ngexesha lokusetyenziswa. Oko kukuthi, phantsi kweemeko zobuninzi kunye nomgangatho ofanayo, amandla amancinci asetyenziswa ngexesha lenkqubo yokusebenza, kubandakanywa nezibonelelo ezahlukeneyo ezifana namanzi kunye nombane.
Okwesibini, izikhululo zokuxuba i-asphalt zekhonkrithi ezihambelana nokusingqongileyo azifuni nje ukusetyenziswa kwamandla amancinci, kodwa kufuneka zifezekise ukusebenza kakuhle kwemveliso, kwaye kwangaxeshanye zinciphise ukukhutshwa kwekhabhoni kuyo yonke inkqubo yokuvelisa, ukuze kuhlangatyezwane neemfuno ezicetywayo zokuvelisa i-carbon low-carbon.
Ukongezelela, kuphela abo banokulawula ngokufanelekileyo ukungcola okwenziwe kunye nokunciphisa umonakalo othe ngqo kwimo engqongileyo obangelwa ukungcola okwenziwa ngexesha lenkqubo yokuvelisa bafanelekile ukuba bachazwe njengezikhululo zokuxuba i-asphalt ikhonkrithi ehambelana nokusingqongileyo. Kukho neemfuneko zokucwangciswa kwesityalo sayo, nokuba yindawo yemveliso okanye indawo yokuguqulwa kwamanzi amdaka kunye negesi eyinkunkuma, kufuneka ibe nengqiqo.
Ngokwesiqhelo, izikhululo zokuxuba i-asphalt zekhonkrithi ehambelana nokusingqongileyo, njengezikhululo zokuxuba zekhonkrithi ze-asphalt eziqhelekileyo, zinokwahlulwa zibe ziindidi eziphazamisayo neziqhubekayo. Kodwa kungakhathaliseki ukuba yeyiphi na ifom, inokuxuba kwaye igxobhoze i-aggregates eyomileyo kunye neshushu yobukhulu bamasuntswana ahlukeneyo, iifayili kunye ne-asphalt ibe ngumxube ofanayo ngokuhambelana nomlinganiselo owenziweyo wokuxuba kwiqondo lokushisa elichaziweyo.
Kuphela iseti epheleleyo yezityalo zokusingqongileyo zokuxuba i-asphalt zekhonkrithi ezihlangabezana nezi meko zokusingqongileyo kunye neemfuno zokusebenza ezinokuthi zisetyenziswe ngokubanzi kulwakhiwo oluthile lobunjineli olufana nohola wendlela ephezulu, iindlela zasezidolophini, izikhululo zeenqwelo moya, iidocks, iindawo zokupaka, njl. umgangatho we-asphalt kwipavumente.
