Lub thev naus laus zis ntawm kev sib khi tshuab gravel uas yog ib qho cuab yeej tuaj yeem kis cov khoom sib thooj thiab pob zeb tib lub sijhawm. Cov asphalt thiab pob zeb yuav tsum ua ke hauv ib ob. Qhov kub ntawm cov kub asphalt yog 140 ° C thaum cov ntaub ntawv ua kom tawg, thiab qhov ntsuas kub tuaj yeem lav tau saum 120 ° C thaum lub sijhawm sib raug zoo. Cov asphalt kub poob me me me. Nyob rau lub sijhawm no, lub fluidity ntawm cov asphalt binder yog tseem zoo heev, thiab thaj chaw sib raug zoo nrog lub pob zeb loj, uas tau txhim kho txoj kev sib txuas nrog lub pob zeb. Lub zog ntawm lub pob zeb sib khi. Cov ib txwm muaj kev sib khi ua ke yog siv ob qho sib txawv thiab ob qho txheej txheem rau kev sib kis. Xws li lub sijhawm tsim kho ntev yuav ua rau qhov kub ntawm asphalt kom poob qis, thiab cov nyiaj tsis zoo ntawm lub pob zeb loj thiab cuam tshuam rau kev ua tau zoo ntawm kev sib khi txheej.
Synchronous gravel seering tshuab muaj cov yam ntxwv hauv qab no:

(1) waterproofantness zoo dua. Lub sijhawm txau ntawm cov ntaub ntawv uas tau khi rau hauv txoj kev sib nraus, yog li kev txhim kho cov kab nrib pleb
(2) Zoo adhesion thiab anti-diab ntawm cov khoom. Asphalt lossis lwm cov ntaub ntawv khi cov ntaub ntawv cog lus ua rau muaj kev sib sau ua ke rau txoj kev qub. 1 / 3 ntawm cov aggregegregregregregrege tuaj yeem tiv thaiv cov log tsheb ncaj qha. Nws roflness nce kev sib txhuam coefficient nrog cov log tsheb, txhim kho cov nplaum thiab cov nplaum ntawm txoj kev nto. Npleem tsis kam.
(3) hnav tsis kam thiab kav ntev. Lub gravel thiab asphalt kis ib ib txhij ua rau thaj tsam asphaltly, thiab 2 ntawm qhov siab ntawm thaj chaw asphalt, thiab ib qho siab concave tuaj yeem tsim vim yog tag nrho cov quab yuam ntawm kev ua si liphalt binder ntawm asphalt binder. Nws yog ze ze nrog gravel kom tiv thaiv cov gravel, yog li synchronous gravel foob muaj cov coj zoo thiab kav ntev. Qhov no tseem yog ib qho tseem ceeb rau cov khoom siv thev naus laus zis synchronous tshuab kom txuas ntxiv txoj kev ua haujlwm ntawm txoj kev.
(4) kev lag luam. Tus nqi-ua tau zoo ntawm tib lub sijhawm gravel sealing yog qhov zoo dua li lwm txoj kev kho kev kho mob hauv txoj kev, yog li txo kev tswj hwm txoj kev.
(5) Cov txheej txheem kev tsim kho yog yooj yim, kev tsim kho nrawm nrawm, thiab cov tsheb khiav tuaj yeem qhib hauv lub sijhawm.
