Piv nrog rau cov lus txhais ntawm qhov kub thiab txias rov qab, cov khoom siv raw rau emulsified hloov kho asphalt khoom yog txias patching, uas siv qhov kub thiab txias tsis tshua muaj kub raw cov ntaub ntawv rau rov qab. Cov khoom siv rov ua dua qub yog cov khoom siv txias txias.

Qhov sib txawv ntawm emulsified hloov kho asphalt cov khoom ua vaj tse thiab cov khoom siv kho dua tshiab yog tias nws muaj cov khoom sib txuas thiab cov yam ntxwv xoob. Piv nrog rau cov tsoos kub patching, nws zam cov tsoos kub patching txheej txheem ntau lawm xws li round pit square patching thiab txhuam nrog hauv qab roj, thiab ua rau cov tsoos kub patching txheej txheem. Qhov tsis zoo ntawm kev tsis tuaj yeem ua haujlwm hauv kev tsim kho thaum lub caij ntuj no thiab lub caij ntuj no tsis muaj peev xwm txuag tau qhov tsis yooj yim ntawm kev teeb tsa lub lauj kaub thiab qhov cub kom sov asphalt ntawm qhov chaw.
Cov khoom siv zoo li no tuaj yeem siv los kho ntau hom kev npog hauv pem teb hauv txhua qhov huab cua thiab thaj chaw ib puag ncig ntawm kev ua haujlwm kub ntawm -30 ° C thiab 50 ° C. Nws yuav tsis ua pa phem rau huab cua thiab dej hauv av, thiab tuaj yeem rov ua dua thaum nws tawg. Tom qab kev rov qab los, Kev tsheb khiav hauv nroog tuaj yeem rov qab los ntawm kev puas tsuaj yooj yim, kev ua haujlwm ntawm tib neeg, lossis lub log tsheb.
Nws cov khoom muaj zog tiv thaiv kev laus thiab kev sib txuas ua ke ua rau txoj kev rov qab los tsis tshua muaj kev poob los yog tawg, thiab nws lub neej kev pabcuam tuaj yeem muaj ntau tshaj tsib xyoos.
Cov ntaub ntawv raw ntawm emulsified hloov kho asphalt khoom tam sim no nyob rau hauv kev ua lag luam xa mus rau discolored asphalt, xuab zeb thiab gravel ntawm ntau yam xim, thiab dyes uas yog tov thiab stirred ntawm ib tug tshwj xeeb kub los tsim asphalt sib tov ntawm ntau yam xim, thiab ces paved. , dov thiab ces dov los tsim cov yeeb yuj asphalt qhob pavement nrog qee lub zog tensile thiab cov yam ntxwv ntawm txoj kev, tseem hu ua emulsified modified asphalt khoom.
