1. Pob tshab txheej siv tshuab
1. Muaj nuj nqi thiab siv tau
(1) Lub luag haujlwm ntawm cov txheej txheem permeable: Txhawm rau ua kom cov asphalt nto txheej thiab txheej txheej hauv paus zoo sib xyaw ua ke, emulsified asphalt, thee pitch lossis kua asphalt yog nchuav rau hauv txheej txheej los tsim cov txheej nyias nyias uas nkag mus rau hauv qhov chaw. lub hauv paus txheej.
(2) Txhua hom txheej txheej ntawm asphalt pavement yuav tsum tau txau nrog cov roj nkag. Thaum teeb tsa cov txheej txheem qis rau ntawm lub hauv paus txheej, cov roj permeable yuav tsum tsis txhob muab tshem tawm.
2. Cov kev cai dav dav
(1) Xaiv cov kua asphalt, emulsified asphalt, thiab thee asphalt nrog permeability zoo li cov roj nkag, thiab paub meej tias nws los ntawm kev drilling lossis khawb tom qab txau.
(2) Lub viscosity ntawm cov roj permeable asphalt tuaj yeem hloov kho kom haum rau cov viscosity los ntawm kev kho cov nqi diluent lossis cov concentration ntawm emulsified asphalt.
(3) Cov roj nkag tau siv rau cov txheej txheem semi-rigid yuav tsum tau txau tam sim tom qab txheej txheej txheej yog dov thiab tsim, thaum lub npoo qhuav me ntsis tab sis tseem tsis tau tawv.
(4) Lub sij hawm txau cov roj nkag: Nws yuav tsum tau txau 1 mus rau 2 hnub ua ntej paving txheej asphalt.
(5) Lub sijhawm kho tom qab cov roj txheej nkag mus tau raug txiav txim siab los ntawm kev sim los xyuas kom meej tias cov diluent hauv cov kua asphalt yog volatilized kiag li, cov emulsified asphalt nkag mus thiab cov dej evaporates, thiab asphalt nto txheej yog nteg sai li sai tau. .

3. Ceev faj
(1) Cov roj nkag 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 yuav tsum tsis txhob tsim cov roj zaj duab xis rau saum npoo.
(2) Thaum qhov kub qis dua 10 ℃ los yog cua daj cua dub los nag, tsis txhob tsuag cov roj nkag.
(3) nruj me ntsis txwv tsis pub dhau ntawm tib neeg thiab tsheb tom qab txau cov roj nkag.
(4) Tshem tawm ntau tshaj asphalt.
(5) Kev nkag mus tag nrho, 24 teev.
(6) Thaum cov txheej txheej saum npoo tsis tuaj yeem ua rau lub sijhawm, nthuav tawm cov pob zeb pob zeb lossis cov xuab zeb ntxhib.
2. Kev tsim kho tshuab ntawm cov nplaum txheej
(1) Muaj nuj nqi thiab siv tau
1. Kev ua haujlwm ntawm cov nplaum nplaum: kom ua tiav cov txheej txheem sab saud thiab qis asphalt lossis asphalt structural txheej thiab cov qauv (los yog cov cement pob zeb pavement) rau hauv tag nrho.
2. Yog tias muaj raws li hauv qab no, cov nplaum txheej asphalt yuav tsum tau txau:
(1) Nruab nrab asphalt txheej ntawm ob txheej los yog peb-txheej kub-txheej kub-paved asphalt sib tov pavement.
(2) Ib txheej asphalt yog muab tso rau ntawm cov cement pob zeb pavement, asphalt stabilized gravel puag lossis qub asphalt pavement txheej.
(3) Cov sab qhov twg curbs, rainwater inlets, soj ntsuam lub qhov dej thiab lwm yam yog nyob rau hauv kev sib cuag nrog tshiab paving asphalt sib tov.
(2) Cov kev cai dav dav
1. Kev xav tau rau cov nplaum txheej asphalt. Tam sim no, nrawm nrawm lossis nruab nrab-kawg emulsified asphalt thiab hloov kho emulsified asphalt feem ntau yog siv los ua cov ntaub nplaum nplaum asphalt. Kev ceev thiab nruab nrab qhov chaw ua kua roj av asphalt kuj tseem siv tau.
2. Qhov ntau npaum li cas thiab ntau yam xaiv ntawm cov nplaum txheej asphalt.
(3) Cov lus ceeb toom
(1) Qhov chaw txau yuav tsum huv thiab qhuav.
(2) Nws yog txwv tsis pub siv tshuaj tsuag thaum kub qis dua 10 ℃ lossis txoj kev ntub dej.
(3) Siv asphalt kis cov tsheb thauj khoom los txau.
(4) Tom qab txau cov nplaum txheej asphalt, nco ntsoov tos kom cov emulsified asphalt tawg thiab cov dej kom evaporate ua ntej nteg txheej txheej ntawm asphalt pob zeb.
