Lub Hom Phiaj Hloov Kho Cov Ntaub Ntawv: Ntxiv cov hloov kho tshiab thiab cov tshiab hloov kho rau cov roj ntsha ua tau zoo, muaj xws li cohesion, kev tiv thaiv kub thiab qhov tseem ceeb txuas kev tiv thaiv cov haujlwm.

Lub hauv paus ntsiab lus hloov tshiab: asphalt cov khoom sib xyaw ua ke muaj kev sib xyaw ntawm Aspastres, collagen fibers, paraxylene thiab saturated hydrocarbons. Asphaltenes vam khom rau collagen fibers mus rau disperse hauv paraxylene thiab saturated hydrocarbons los tsim cov qauv tshuaj colloidal. Asphaltene thaum cov khoom xyaw me me, bitumen muaj cov nplaum zoo, riam phom yas deformation, thiab qhov kub thiab txias. Cov kev hloov kho polymer yog zoo li cov aspaltreure hauv asphalt. Nws ntxiv, tom qab txaus yaj thiab oping thiab collagen fibers nyob rau hauv asphalt bibers hauv asphaltbed los ua ib qho kev daws teeb meem tshiab. Thaum lub sij hawm sib xyaw ua ke ntawm cov sib tov, tus neeg sawv cev sib xyaw sov thiab asphalt yog txau rau hauv lub lauj kaub ua ke. Raws li kev sib xyaw txhua yam, muaj ntau ntau ntawm surfactant micellhaltes tau nkag mus rau hauv ib pab dej hiav txwv sai sai, thiab cov dej sab nraud sai sai thiab poob, ua rau cov papophilic tiv thaiv cov asphalt; Thaum cov dej uas tseem tsis tau ploj yog nyob rau hauv kev sib cuag nrog cov pab pawg hydrophilic ntawm lub surfactant. Ua ke, muaj ntau tus nqi ntawm cov dej shrinkating nrog lubricating cov nyhuv yog tsim ntawm nruab nrab ntawm cov txiv ntoo sib xyaw; Los ntawm lubricating nyhuv ntawm cov dej shrinkage, nws tsis yog txhim kho kev ua kom sib xyaw ntawm kev sib xyaw, tab sis kuj yog zam qhov teeb meem rau qee yam. Asphalt cug yog clumping.
Qhov no tsis tsuas yog khaws cia lossis txhim kho cov adminalion, yog kuj txhim kho qhov kev ua kom asphalt, yog li ua tiav lub hom phiaj ntawm kev txhim kho kev ua haujlwm asphalt txuas hniav;
Hloov kho cov khoom siv thev naus laus zis: tus hloov kho thiab kho kom zoo nkauj rau hauv lub tshuab asphalt thiab tom qab ntawd nws tau txiav los ntawm cov qoob loo ntawm kev ua kom zoo nkauj thiab cov qauv hloov kho kom meej, kev loj hlob thiab loj hlob. Nws tsis tsuas yog nce txoj kev siv ntawm kev hloov kho tab sis kuj txhim kho kev ua tau zoo ntawm thawj cov thawj asphalt.
