Nrog rau kev txhim kho txuas ntxiv ntawm tib neeg, kev txhim kho txuas ntxiv ntawm kev lag luam thiab thev naus laus zis, kev lag luam kev loj niaj hnub kuj tseem txhim kho sai, thiab cov kev xav tau ntawm cov ntaub ntawv pavement tau nce siab dua. Cov ntaub ntawv hloov kho bitumen zoo heev yog sib cais los ntawm kev hloov kho bitumen cov ntaub ntawv sib txuas. Cov khoom siv bitumen. Yog li dhau ntawm cov xwm txheej no, lwm yam laj thawj dab tsi uas peb tsis nkag siab? Cia peb saib:
1) Qee cov cuab yeej hloov kho bitumen hauv kev ua lag luam tsis cuam tshuam nrog SBS thaiv qhov teeb meem ua ntej sib tsoo, tsis muaj pretreatment txaus thiab cov qauv ntawm lub zeb tsis tsim nyog. Cov txheej txheem sib tsoo tsis tuaj yeem ncav cuag qee qhov zoo, ua rau hloov kho bitumen. Kev tsim khoom ntawm cov khoom tsis muaj tshuaj lom bitumen tsis siab thiab cov khoom zoo tsis ruaj khov. Nws yuav tsum tau cia siab rau kev sib tsoo rov ua dua thiab ua rau lub sijhawm ntev los daws qhov teeb meem. Qhov no tsis tsuas yog ua rau kev siv zog ntau thiab cov nqi, tab sis kuj ua rau cov khoom tsis ruaj khov thiab cuam tshuam rau kev tsim kho ceev ntawm txoj kev loj.
2) Vim yog txoj hauv kev tsis tsim nyog, kev poob ntawm lub zeb yog loj thiab qhov zoo ntawm cov khoom hloov bitumen tsis ruaj khov. Vim tias qhov o thiab nplawm SBS feem ntau tsim qee cov pob lossis cov khoom loj dua, thaum nws nkag mus rau hauv chav sib tsoo, vim muaj qhov chaw tsawg thiab lub sij hawm sib tsoo luv luv, lub zeb ua rau lub siab loj, thiab kev sib txhuam sai sai, ua rau muaj kev sib txhuam loj heev. tshav kub nce qhov kub ntawm qhov sib tov, uas tuaj yeem yooj yim ua rau qee qhov bitumen rau hnub nyoog. Kuj tseem muaj ib feem me me uas tsis tau muaj av txaus thiab ncaj qha rushed tawm ntawm lub tank sib tsoo. Qhov no muaj kev cuam tshuam ncaj qha rau qhov zoo, qhov zoo, thiab ntws tus nqi ntawm cov hloov bitumen, thiab ua rau lub neej luv ntawm lub zeb.
Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau txhim kho cov txheej txheem hloov kho bitumen thiab khoom siv. Txhawm rau kov yeej cov teeb meem tshwm sim hauv kev ua cov ntaub ntawv hloov kho bitumen bonding, peb lub tuam txhab tau ua kom zoo rau kev tsim cov txheej txheem kev hloov kho bitumen thiab ua cov qauv kev txhim kho rau homogenizer thiab zeb. Los ntawm kev sim thiab lub sijhawm ntawm kev tsim khoom, nws tau raug pov thawj tias cov teeb meem saum toj no tuaj yeem daws tau tag nrho. Peb tau siv cov thev naus laus zis ntau lawm los tsim ib pawg ntawm cov khoom siv zoo hloov kho bitumen, uas tau txhim kho kev tsim khoom thiab txo qis kev siv hluav taws xob thiab hluav taws xob, uas muaj qee yam cuam tshuam rau kev txuag hluav taws xob. Cov neeg siv tshiab thiab qub zoo siab txais tos hu rau peb rau kev sab laj.
