Umthengi uthatha isigqibo sokuthenga isityalo sokuxuba i-asphalt. Kumsebenzisi, ixabiso liyinto ebalulekileyo ekugqibeni ukuthenga. Iinjineli zethu zokuthengisa ziya kukunika iingcebiso malunga nendlela yokukhetha isityalo se-asphalt, kwaye siya kwenza ngokwezifiso isityalo sokuxuba i-asphalt ngaphandle kokuhlawula imali eninzi. Ngophuhliso oluqhubekayo lothutho lwehlabathi, imfuno yokuxutywa kwe-asphalt inkulu, ke lungakanani utyalo-mali olufunekayo kutyalo-mali kwisityalo sokuxuba i-asphalt?

Ngokotyalo-mali kwiseti ye-HMA-B1500 yebhetshi yokuxuba isityalo se-asphalt, iindleko zeenkcukacha zezi zilandelayo:

1. Ukurenta indawo
Kwisityalo sokuxuba i-asphalt, eyona mfuneko isisiseko kukuba nesiza esifanelekileyo. Ummandla wesiza kufuneka ube mkhulu ngokwaneleyo ukuhlangabezana nokubekwa kwezixhobo zemihla ngemihla kunye nokuhamba kwesiqhelo kwezithuthi zothutho lwe-asphalt. Ke ngoko, indawo yokurenta ixabisa i-30,000 yeedola ngonyaka. Eyona ndawo yokusebenza isafuneka ekubaleni.

2. Iindleko zezixhobo
Eyona nto ibaluleke kakhulu kwisityalo sokuxuba i-asphalt zizo zonke iintlobo zezixhobo zokusebenza. Kuphela ngesixhobo esinokuthi imixube ye-asphalt iveliswe ngokuqhelekileyo. Ke ngoko, xa utyala imali kwisityalo se-asphalt, kufuneka ukhethe izixhobo zokuxuba kunye neziphumo ezahlukeneyo ngokwemeko yakho yezoqoqosho. Iindleko zezixhobo jikelele ziphakathi kwe-30-45 yezigidi zeedola.

3. Iindleko zezinto eziphathekayo
Ngaphambi kokuveliswa okuqhelekileyo kwesityalo sokuxuba i-asphalt, kuyimfuneko ukuthenga isixa esikhulu sezinto eziluhlaza. Kuyimfuneko ukuvelisa i-asphalt ehambelanayo ngokomyalelo wayo. Izixhobo kufuneka zithenge i-coarse aggregate, i-fine aggregate, i-screening gravel, i-slag, i-slag yensimbi, njl., ukwenzela ukuba ikwazi ukuhlangabezana neemfuno ezahlukeneyo. Iimfuno zeodolo, ngoko kubiza i-70-100 ikhulu lamawaka eedola.

4. Iindleko zomsebenzi
Kwisityalo sokuxuba i-asphalt, nangona sinezixhobo zokuvelisa kunye nezinto eziluhlaza, kusafuna inani elikhulu labasebenzi ukuba basebenze, ngoko ke iindleko zabasebenzi besityalo sokuxuba i-asphalt nazo kufuneka zithathelwe ingqalelo. Inani elithile labasebenzi kufuneka lijongwe ngokobungakanani bendawo. Ngokuqhelekileyo Kuyimfuneko ukulungiselela malunga ne-12-30 ikhulu lamawaka eedola.

5. Ezinye iindleko
Ukongeza kwezi zinto zingentla ekufuneka zichithwe, kuyafuneka ukuba kuqwalaselwe iindleko zokusebenza kweplanti yokuxuba i-asphalt, iindleko zamanzi kunye nombane, iindleko zokuqhuba iziqinisekiso, kunye neemali zogcino lweshishini, njl., ezifuna malunga ne-30,000 yeedola.

Oku ngasentla ziindleko ezineenkcukacha zotyalo-mali kwiplanti yokuxuba i-asphalt. Ukushwankathela, utyalo-mali kufuneka lubize i-42-72 yezigidi zeedola. Kuxhomekeke kubukhulu besityalo sokuxuba i-asphalt.
