Sinoroader emulsified asphalt pavement engineering cov cuab yeej siv, tam sim no tau maj mam siv dav.
Peb txhua tus paub tias ua ntej yuav siv cov cuab yeej siv, cov cuab yeej yuav tsum tau tshuaj xyuas ua ntej los xyuas seb lub installation puas zoo li qub, thiab tom qab ntawd muab tso rau hauv kev siv. Kev siv cov cuab yeej hloov kho asphalt hloov kho asphalt ntau lawm tuaj yeem txuas ntxiv rau lub caij nyoog kawg. Kev hloov kho asphalt thiab pob zeb dej tshuab tuaj yeem sib xyaw nrog cov pob zeb ntub dej los tsim cov yeeb yaj kiab tas li nyob rau hauv qhov chaw ntawm qhov kub thiab txias asphalt thiab pob zeb. Lub viscosity ntawm asphalt yog tsawg thiab viscosity ntawm emulsified asphalt yog tsawg. Cov yeeb yaj kiab ntub dej hauv qab 10 degrees.

Tshawb xyuas lub tshuab hloov kho emulsified asphalt hloov khoom siv. Yog tias lub tshuab emulsified asphalt colloid emulsion siv tau ntev, lub tshuab dov yuav loj dua, yog li lub sij hawm no peb yuav tsum tau kho nws mus ntxiv ntau lawm. Qhov no yog ib qho teeb meem yooj yim. Rau kev tsom xam ntawm tus hloov kho, tus nqi dav dav ntawm kev hloov kho ntxiv yuav tsum tau hloov kho raws li qhov sib txawv ntawm cov dej zoo thaum ntxiv tus nqi pH. Qhov teeb meem yuav tsum tau soj ntsuam los ntawm cov kws tshaj lij. Cov cuab yeej hloov kho asphalt nws tus kheej yog qhov teeb meem tshwm sim, vim tias asphalt zoo tib yam kuj muaj cov kev faib tawm sib txawv. Thaum tsim kho asphalt, kev saib xyuas yuav tsum tau them rau qhov xav tau ntawm cov khoom siv raw, uas yog asphalt zoo tib yam thiab zoo.
Cov khoom uas yuav tsum tau kuaj xyuas cov cuab yeej hloov kho asphalt yog thaum kuaj xyuas. Peb yuav tsum ua haujlwm kom raug raws li cov lus qhia. Tsuas yog hauv txoj kev no peb tuaj yeem ua tiav cov txiaj ntsig zoo dua. Yog tias koj tsis nkag siab dab tsi, thov koj xav tiv tauj peb hauv lub sijhawm.
