Qhov sib txawv ntawm asphalt nkag siab txheej, txheej tav thiab ntaub ntim txheej!
Kev tsim kho cov kev tsim kho ntawm asphalt nkag siab txheej yog raws li hauv qab no: hauv 6 teev tom qab txheej txheej roj yuav tsum tau muab txau hauv lub sijhawm. Lub Penetration roj siv emulsified asphalt PC-2, thiab nws liters tau txiav txim siab los ntawm kev sib tsoo tshuaj, thiab lub tob tob yuav tsum tsis pub tsawg tshaj 5mm. Tom qab txau cov roj penetration, cov emulsified asphalt pc-1 qis dua cov khoom siv ascases, qhov twg lub embulgeifield ntau npaum li cas yog 0.5-1cness yuav tsum tsis pub tsawg tshaj 0.6 cm. Ua ntej paving roj av yuav tsum tau muab txau rau ntawm cov txheej txheem sab saud, zoo li ntawm cov ntug dej hiav txwv, tshuaj xyuas cov teeb meem dej nag thiab lwm yam qauv. Cov roj tack siv emulsified asphalt pc-3, thiab cov tshuaj 0.age yog 0.5 liv ib square Meter.

Nyob rau hauv cov dej nag thiab av noo, yog tias cov txheej txheem asphalways thiab yog tsim nyog rau Paved txheej txheem tom qab tshuaj tsuag permeable.
Nws yog ib qho tsim nyog yuav nruj me ntsis cov txheej ntawm cov roj qis dua thiab cov txheej txheem tso tawm: Lub hom phiaj ntawm cov txheej hauv qab, thiab nws tsis tas yuav nkag mus; Cov roj permeable permable yuav tsum nkag mus rau qee qhov tob. Kuj tseem muaj qhov sib txawv loj hauv lawv cov haujlwm thiab cov hom phiaj. Hauv qee qhov haujlwm tam sim no, txij li cov roj permeable tsuag tsis tuaj yeem nkag mus, agregates thiab xuab zeb tau txau cov roj permeable raws li cov txheej hauv qab. Qhov no tuaj yeem ua lub luag haujlwm sib khi, tab sis nws tsis tuaj yeem hloov cov roj txheej permleable.
Slurrry foob feem ntau yog siv rau kev tiv thaiv txij nkawm ntawm chav kawm thib ob thiab qis-txoj kev loj, thiab tseem muaj rau cov txheej hauv qab ntawm cov kev loj tshiab.
Cov txheej qis qis dua tau teev nyob rau saum npoo ntawm lub hauv paus semi-rigid puag. Nws cov haujlwm yog: Ua ntej, los tiv thaiv lub hauv paus los ntawm kev puas tsuaj los ntawm kev tsim kho cov tsheb, uas yog qhov ua rau cov khoom kho kom zoo rau kev kho cov ntaub ntawv semi-rigid; Thib ob, kom tiv thaiv dej nag los ntawm kev pom hauv cov txheej txheem txheej txheem hauv qab no hauv paus; Thib peb, kom ntxiv dag zog rau kev sib xyaw ntawm cov txheej saum npoo thiab lub hauv paus. Muaj ntau txoj hauv kev los ua kom cov txheej ntim qis dua. Kev xyaum ua tau pom tias ib txheej ntawm asphalt yog ib txoj kev lag luam ntau tshaj plaws thiab cov qauv siv tau zoo.
Cov haujlwm thiab cov mob uas siv tau ntawm asphalt nkag, txheej txheej tav thiab kaw txheej muaj raws li hauv qab no:
(1) muaj nuj nqi thiab siv cov xwm txheej ntawm cov txheej nkag
Txoj haujlwm ntawm cov txheej nkag yog ua kom cov khoom siv asquhalt txheej thiab asphalt buas txheej zoo sib khi ua ke. Nws yog ib txheej nyias nyias uas nkag mus rau txheej saum npoo ntawm cov txheej ntawm cov txheej los ntawm cov roj pleev emulsified, thee li tar lossis kua asphalt ntawm lub hauv paus txheej.
Thaum cov xwm txheej hauv qab no tau ntsib, nkag mus rau txheej Asphalt yuav tsum tau sprinkhled:
① Graded Gravel thiab graded crushed pob zeb ntawm asphalt pavement.
② Maas Caas, Qeeb, ya tshauv thiab lwm yam inorganic bindilize av.
③ Nkag mus rau txheej Asphalt yuav tsum yog sprinkhalt yuav tsum yog sprinkhled ntawm semi-rigid paus ntawm cov khoom siv granular.
(2) ua haujlwm thiab muaj cov xwm txheej ntawm cov txheej txheem khi
Txoj haujlwm ntawm cov txheej txheem khi yog kom txhawb txoj kev sib khi ntawm asphalt txheej thiab ntawm asphalt txheej los ntawm sprinkling ib txheej asphalt.
Cov Khaub Ncaws Hnav As As As As As As As As As As As As As As As As As As As As As As As As As As As As As As As As As As Asly:
① Cov txheej Asphalt txheej hauv qab no ob-txheej lossis peb txheej kub-LOV-Laid As-Lauj dej sib xyaw ua ntej cov txheej txheem sab saud yog pua.
② ASPHALT txheej yog ntxiv rau ntawm cov txheej txhab asphalt qub txheej.
③ Cov txheej Asphalt sab npoo av yog nteg rau ntawm cov cement pob zeb ua.
Ntawm ob sab ntawm curbs, dej nag, tshuaj ntsuam kom zoo, thiab lwm yam uas muaj kev sib cuag tshiab ntawm tus tshiab tso ashly ashint.
(3) muaj nuj nqi thiab tsim nyog ntawm cov ntaub ntim
Txoj haujlwm ntawm cov txheej ntim cov txheej yog los txiav cov khoob npoo thiab tiv thaiv kom noo los ntawm kev nkag mus rau saum npoo txheej lossis txheej txheej. Cov txheej paved ntawm txheej saum npoo yog hu ua txheej saum toj kawg nkaus yog hu ua txheej txheej sab saud, thiab txheej pua pua hauv qab ntawm txheej txheej hauv qab.
Cov txheej txheej saum toj sab saud yuav tsum tau muab tso rau ntawm lub pob zeb asphalt sab hauv cov rooj plaub hauv qab no:
Qhov khoob hauv cov txheej Asphalt saum npoo av loj thiab dej permeability yog loj.
② qhov qub asphalt txoj kev taug kev nrog cov kab nrib pleb lossis kev kho kom haum.
③ Qhov kev ua ashrhalt txoj kev taug kev uas yuav tsum tau ua tus hnav hnav los ua kom muaj kev ua tau zoo los txhim kho kev ua yeeb yam los ntawm kev tawm tsam.
Reminhal fab kev taug kev tshiab tshiab uas yuav tsum tau ua kom pua cov ntoo txheej lossis txheej tiv thaiv.
(4) lub luag haujlwm thiab muaj feem xyuam ntawm slurry foob
Lub luag haujlwm ntawm cov pob zeb slurry: nws yog cov pob zeb asphalt sib xyaw ua ke tau los ntawm cov neeg asphalt, thiab lwm yam.
Cov txheej hauv qab cov txheej yuav tsum tau nteg nyob rau hauv asphalt sabfoo ncej txheej txheem hauv qab no yog ntsib:
① Nyob rau hauv thaj chaw los nag thiab thaj av asphalt muaj cov khoob loj thiab dej txaus nyiam.
② Tom qab txheej txheej txheej yog pua txheej, cov txheej txheem asphalt sab hauv lub sijhawm, thiab tsheb yuav tsum qhib.
