Lub hauv paus txheej ntawm asphalt pavement tau muab faib ua ib nrab thiab tsis yeem. Txij li thaum pib txheej thiab txheej txheej saum npoo yog cov khoom siv ntawm cov khoom sib txawv, kev sib txuas lus zoo thiab txuas ntxiv ntawm ob yog cov tseev kom tseem ceeb ntawm ob yog cov tseev kom tseem ceeb ntawm ob yog cov kev cai tseem ceeb rau cov hom ntawm no. Ib qho ntxiv, thaum cov dej assalt shopa dej, feem ntau yuav muaj cov txheej txheem li saum npoo av xws li slurry, looseness, thiab potholes. Yog li no, ntxiv ib txheej ntim qis dua nyob rau sab saum toj ntawm ib nrab ntawm cov txheej txheem tseem ceeb hauv kev txhim kho lub zog, kev ruaj khov thiab kev nqus dej ntawm cov txheej txheem txheej txheem txheej txheem. Feem ntau siv ib yog siv asphalt gravel squchronous sealing thev naus laus zis.

Yog li cia peb mus saib yuav ua li cas kev tsim kho asphalt gravel squchronous foob tsheb yog nqa tawm:
(1) crushing. Cov txheej dej dej uas nyuam qhuav tau sprinkled (sprinkled) tsis tau muab dov tam sim ntawd, txwv tsis pub cov qib siab tau hloov zuj zus thiab tshem tawm cov pob zeb. Thaum qhov ntsuas kub ntawm SBS hloov asbs hloov asphalt detps txog 100 ° Tsheb thiab tswj cov tsheb thauj khoom nrawm rau ib puag ncig txoj kev tsheb thiab yog li ntawd cov pob zeb as-1, yog li ntawd cov pob zeb loj uas tau hloov kho thiab sib khi ua ke.
(2) txij nkawm. Tom qab cov txheej sealing yog nteg, nws yog nruj me ntsis txwv tsis pub siv cov tsheb thauj mus los thiab ua kom U-tig. Tsheb yuav tsum raug kaw kom txog thaum cov kev tsim kho ntawm SBT kev hloov kho ntawm cov txheej Asphalt, ces txheej qis dua tuaj yeem qhib rau cov roj av nkaus xwb tom qab txheej qis yog pua. Nyob rau saum npoo ntawm waterproof txheej tsim los ntawm cov roj hmab log tsheb cov menyuam, daim ntawv sib khi ntawm gravel thiab asphalt muaj zog heev. Kev hloov kho asphalt muaj kev rov qab zoo nkauj (elastic rov qab) thiab ua tau kev ncua kev ntxhov siab, uas tuaj yeem txo cov kab nrib pleb hauv lub hauv paus txheej ntawm txheej txheej saum npoo av. Reflective kab nrib pleb.
(3) on-site zoo soj ntsuam. Cov tsos tshuaj xyuas qhia tau hais tias aspalt kis los ntawm asphalt Foob Txheej yuav tsum tau sib kis tusyees yam tsis muaj dej los yog ntau dhau txheej; Ib leeg-grained gravel hauv cov asphalt txheej thiab aggrate txheej yuav tsum tau sib kis tusyees yam tsis muaj hnyav lossis xau. Kev kuaj pom cov nyiaj tau faib tau faib ua tag nrho cov nyiaj tau kuaj pom thiab ib qho taw tes nrhiav tau; Cov qub qub tswj tau cov nqe lus sib txuas lus tag nrho, hnyav cov gravel thiab asphalt, suav nrog ntu kev sib koom tes, thiab tom qab ntawd suav nrog ntu kev sib kis tau; Cov tom kawg tswj cov nyiaj thiab kev sib tw ntawm kis ntawm cov ntsiab lus ntawm tus kheej.
