1. Pob tshab Txheej Txheej Txheem Siv Tshuab
1. Muaj nuj nqi thiab siv cov xwm txheej
(1) Lub luag haujlwm ntawm cov txheej permleable: txhawm rau ua cov txheej asphalt, pemulsified asphalt, pulsified asphalt, pulsified asphalt yog penetrates mus rau saum npoo ntawm lub hauv paus txheej.
(2) Txhua yam ntawm lub hauv paus txheej ntawm asphalt pavemental yuav tsum tau txau nrog cov roj txho. Thaum teeb tsa cov txheej sealing hauv qab ntawm txheej txheej txheej, cov roj txheej permleable yuav tsum tsis txhob raug rho tawm.
2.Txhua yuav tsum tau
(1) Xaiv cov kua dej asphalt, Emulsified asphalt, thiab thee asphalt nrog zoo permeability uas yog qhov tseeb tias nws los ntawm kev zom lossis kev khawb tom qab tsuag.
(2) Lub viscosity ntawm pakecosity roj Asphalt tuaj yeem hloov kho viscosity los ntawm kev kho cov nyiaj ntawm diluent lossis kev xav ntawm emulsified asphalt.
(3) Cov roj tob txiav rau cov roj semi-rigid hauv paus txheej yuav tsum tau muab tshem tawm tam sim ntawd tom qab tsim, thaum lub ntsej muag qhuav me ntsis tab sis tseem tsis tau muaj qhov tawv me me.
(4) lub sijhawm rau kev txau cov roj penetrating: nws yuav tsum tau muab tshuaj tsuag 1 mus rau 2 hnub ua ntej paving cov txheej asphalt txheej.
(5) lub sijhawm kho tom qab cov roj nkag mus yog kev sim ua kom ntseeg tau tias cov kua dej asphaltly, thiab cov dej uas aspultifulation
3. Kev ceev faj
(1) Cov roj loj yuav tsum tsis txhob ntws tom qab sib kis. Nws yuav tsum nkag mus rau hauv lub hauv paus txheej rau ib qho tob thiab tsis tas yuav tsim cov roj pleev xim rau saum npoo.
(2) Thaum qhov ntsuas kub qis dua 10 ℃ lossis nws yog cua lossis nws yuav los nag, tsis txhob tshuaj tsuag rau cov roj.
(3) nruj me ntsis txwv txoj kev hla ntawm cov neeg thiab cov tsheb tom qab tshuaj tsuag cov roj tseem ceeb.
(4) Tshem tawm ntau dhau kev asphalt.
(5) tag nrho cov kev nkag mus, 24 teev.
(6) Thaum txheej txheej saum npoo tsis tuaj yeem raug nplua nyob rau hauv lub sijhawm, kis tus nqi uas tsim nyog ntawm pob zeb pob zeb lossis ntxhib xuab zeb.
2. Siv thev naus laus zis ntawm cov nplaum txheej
(1) kev ua haujlwm thiab cov xwm txheej muaj feem xyuam
1. Kev ua haujlwm ntawm cov nplaum txheej txheem: kom tiav daim ntawv sib txuas ntawm sab saud thiab qis dua li asphalt cov txheej txheem thiab cov qauv (lossis MAAs pob zeb ua ke) rau hauv tag nrho.
2. Yog tias cov xwm txheej hauv qab no tau ntsib, nplaum txheej Asphalt yuav tsum tau txau:
(1) Nruab nrab ntawm asphalt txheej ntawm ob-txheej lossis peb-txheej kub-sib tov kub-leem ay-leb txoj kev ua ke.
(2) Ib txheej Ashbal Asphalt yog pw ntawm Caas pob zeb ua kev TEMAGE, ASLAST DID STRIGILED MOBER LOS SIS ELE Asnhalt Systemric txheej.
(3) Cov tog npoo uas muaj cov tshuaj ntsuab, dej nag, tshuaj xyuas kom zoo rau cov qauv zoo thiab lwm yam kev sib cuag tau muaj kev sib tshuam tshiab.
(2) cov kev cai dav dav
1. Kev xav tau rau cov txheej zoo li txheej asphalt. Tam sim no, nrawm-tawg lossis nruab nrab-tawg emulsified asphalt feem ntau yog siv los ua cov khoom siv nplaum asphalt cov ntaub ntawv. Ceev thiab Nruab Nrab Chaw ua kua roj av kuj tseem siv tau.
2. Cov tshuaj thiab ntau yam kev xaiv ntawm cov nplaum txheej asphalt.
(3) yam kom nco ntsoov
(1) cov tshuaj txau yuav tsum huv thiab qhuav.
(2) Nws txwv tsis pub tshuaj tsuag thaum qhov kub nyob qis dua 10 ℃ lossis txoj kev saum npoo av ntub.
(3) Siv cov thauj khoom thauj khoom rau cov tshuaj tsuag.
(4) Tom qab txau cov txheej nplaum asphalt, nco ntsoov tos kom muaj emulsified asphalt mus tawg ua ntej tso txheej txheej asphalt.
