Piv nrog cov tsoos kub thiab kev nce qib kub rov qab, cov qauv siv cov khoom kub qub lossis cov khoom rov qab kub dua yog cov khoom siv raw txias txias.
Qhov sib txawv ntawm emulsified hloov bitumen nroj tsuag pob zeb Piv nrog tsoos kub patching, nws zam cov Tsoos Kub Caij Kub Ntau Lawm Xws Li Caij Ntuj, thiab txuag qhov tsis yooj yim ntawm cov lauj kaub thiab cov qhov cub thiab cov qhov cub ua kom sov bitumen.

Cov ntaub ntawv ntawm no tuaj yeem siv tau ntawm kev ua haujlwm kub ntawm -30 ℃ ℃ ~ 50 ℃ los kho ntau yam hauv av thiab thaj chaw av, thiab tuaj yeem kho kom sai li sai tau thaum nws raug puas. Tom qab rov kho dua, nws tuaj yeem rov qab mus rau nroog loj hauv nroog tom qab kev sib txuas lus yooj yim, phau ntawv kab ke lossis cov log tsheb dov.
Nws cov khoom muaj zog los tiv thaiv kev laus thiab tsevneeg cov khoom ua rau txoj kev rov qab los poob, tawg, thiab nws cov kev pabcuam lub neej ncav cuag ntau tshaj tsib xyoos.
Cov ntaub ntawv raw ntawm lub emulsified hloov cov khoom siv tam sim no ntawm kev sib xyaw nrog ntau yam kub thiab txias rau cov khoom siv kub rau ntau yam
