Blacktop (asphalt) txoj kev tsav tsheb yuav kawg thiab tawg, ua rau tsis zoo thiab tsis ruaj khov. Tsuav qhov kev puas tsuaj raug txwv rau ob peb qhov chaw, tsis tas yuav hu xov tooj rau tus neeg cog lus. Ua ntawv thov txheej tshiab ntawm blacktop patching cov khoom hla qhov kev puas tsuaj yuav txhawb koj txoj kev tsav tsheb rau tus nqi qis dua.
Cov kauj ruam
Ntu 1 ntawm 3: Npaj Txoj Kev Mus Los
Kauj Ruam 1. Txheeb xyuas koj li kev tsav tsheb
Blacktop thaj ua rau thaj tsis tuaj yeem daws txhua qhov teeb meem. Ua tibzoo saib cov cheeb tsam puas ua ntej txiav txim siab yuav ua licas:
- Txog kev nyuaj siab, cov kab nrib pleb me me, thiab cov nab kuab tawg (tawg hauv cov qauv ntsuas), kho lawv tus kheej raws li tau piav qhia hauv qab no.
- Yog tias kev puas tsuaj npog thaj tsam loj ntawm txoj kev tsav tsheb, lossis yog tias muaj qhov tawg ntau dua ¼ "(6mm) dav, tsuas yog kev daws teeb meem tas mus li yog ntiav tus neeg cog lus tshem tawm thiab hloov txoj kev tsav tsheb. muaj hnub nyoog.
- Kev ntiav tus neeg cog lus txhawm rau hla txoj kev tsav tsheb nrog ntau lub blacktop yog qhov pheej yig dua tom qab hloov pauv, tab sis nws tsis pom zoo rau txoj kev tsav tsheb uas muaj teeb meem nqes dej, lossis nrog thaj tsam loj ntawm cov nab kuab tawg.
Kauj Ruam 2. Tshem cov av thiab cov khib nyiab ntawm txoj kev tsav tsheb
Siv lub tshuab cua tshuab nplooj ntoo, lub tshuab cua nrawm nrog lub taub hau, lossis cov khaub ncaws los tshem tawm cov av, hmoov av, thiab pob zeb xoob.
Kauj Ruam 3. Txiav cov nyom thiab cov nyom kom deb ntawm cov ntug kev
Yog tias muaj cov nyom loj hlob tuaj, koj yuav xav txau cov nroj tsuag nrog cov tshuaj tua kab uas siv tau ntev li ob lub lis piam ua ntej pib qhov haujlwm. Qhov no yuav ua kom cov nroj tsuag tsis loj hlob rov qab.
Yog tias cov nyom lossis cov nyom tau loj hlob hauv cov kab tawg hauv txoj kev tsheb, muab lawv tshem tawm nrog tus ntsia hlau, tom qab ntawd txhuam cov kab nrib pleb nrog txhuam
Kauj Ruam 4. Tshem tawm cov roj me me
Thov ib qho tshuaj txhuam degreasing hnyav thiab txhuam nrog txhuam txhuam hlau xaim.
Zam kev siv cov tshuaj ntxhua ntxhua. Lawv yuav tso tsis pom qhov seem tom qab, uas yuav muaj qhov cuam tshuam tsis zoo rau blacktop's adhesion
Kauj Ruam 5. Sau rau hauv lub suburface rau qhov tob
Yog tias thaj chaw ntawm txoj kev tsav tsheb tau tawg tawm thiab nthuav tawm cov hauv qab hauv qab, sau lub qhov nrog av, pob zeb, lossis xuab zeb kom txog thaum nws qib nrog rau lwm qhov hauv qab.
Ntu 2 ntawm 3: Sau Potholes thiab Kev Nyuaj Siab
Kauj Ruam 1. Hnav khaub ncaws tiv thaiv
Hnav cov hnab looj tes, tsom iav qhov muag, thiab lub tes tsho ntev thiab lub ris ntev ua ntej tuav lub blacktop. Txheeb daim ntawv lo khoom rau cov lus qhia kev nyab xeeb.
Kauj Ruam 2. Xaiv qhov txias ncuav cov pothole patching cov khoom
Blacktop (asphalt) kho cov khoom tuaj hauv ob peb yam sib txawv. Cov khoom siv asphalt pothole patching yog qhov kev xaiv zoo tshaj plaws rau qhov uas ploj lawm ntawm asphalt (potholes), thiab rau kev nyuaj siab tob dua 2 ntiv tes (5 cm). Koj yuav xav tau cov khoom txias txias los kho tsev, vim cov khoom kub ncuav xav tau cov tshuab tshwj xeeb.
Kauj Ruam 3. Txiav lub qhov kom tsim cov npoo ncaj
Koj tuaj yeem hla cov kauj ruam no kom txuag tau kev ua haujlwm, tab sis cov khoom siv sib txuas ua ke yuav tsim kom muaj zog dua, ua kom ntev dua nyob rau hauv lub qhov nrog cov npoo ntsug. Asphalt pom yog txoj hauv kev yooj yim tshaj plaws kom ua tiav qhov no, tab sis koj tuaj yeem siv rauj thiab txiab txhawm rau txhawm rau txhawm rau ntawm ntug ntawm lub qhov.
Ntxuav tawm ib qho hmoov av thiab tawg asphalt tsim los ntawm cov txheej txheem no
Kauj Ruam 4. Ncuav rau txheej txheej ntawm cov khoom ntim
Ncuav nws ncaj qha los ntawm lub hnab kom txog rau thaum koj tau ntxiv ½ rau 1 (1.25 txog 2.5 cm) txheej thoob plaws hauv lub qhov. Rau qhov loj dua, kis cov khoom ib puag ncig nrog rake lossis duav.
Nws tsis yog teeb meem yog tias cov khoom tawg mus rau saum npoo ib puag ncig
Kauj Ruam 5. Tamp nws
Thawb cov khoom ntim nrog lub pothole tamper, vibrating plater, cov nyom nyom, lossis lwm yam khoom hnyav.
Rau thaj tsam loj, koj tuaj yeem roj ib daim plywood los tiv thaiv kom tsis txhob lo, tom qab ntawd muab nws tso rau sab sab ntawm lub thaj. Tsav hla cov plywood kom sib dhos cov khoom hauv qab
Kauj Ruam 6. Rov ua dua kom txog thaum lub qhov puv lawm
Ua ntawv thov txuas ntxiv thiab ua cov txheej txheej ntawm cov khoom sib txuas kom txog thaum lub qhov yog theem nrog txoj kev tsav tsheb ib puag ncig. Siv cov txheej tsis tuab dua 1 (2.5cm) yuav pab tiv thaiv huab cua kom tsis txhob tsim thiab ua kom tsis muaj zog.
Kauj Ruam 7. Kaw thaj tsam thaum muaj kev tso cai
Ua ntawv thov lub asphalt sealer hla kev kho yuav ua rau nws ruaj dua. Txawm li cas los xij, koj tsuas tuaj yeem siv lub foob rau qee yam xwm txheej:
- Tos tsawg kawg 4 teev rau thaj tsam kho, lossis raws li qhia hauv daim ntawv qhia qhia.
- Tos kom txog thaum huab cua tsawg kawg 60ºF (16ºC), txoj kev tsav tsheb qhuav, thiab koj tsis xav tias yuav los nag. Yog tias lub foob ntim tau ntub ua ntej nws kho tau, qee cov ntaub qhwv yuav raug muab tshem tawm.
Ntu 3 ntawm 3: Filling Crack thiab Kev Nyuaj Siab Me
Kauj Ruam 1. Ua raws li cov lus qhia kev nyab xeeb
Txheeb xyuas txhua daim ntawv lo khoom rau cov lus qhia kev nyab xeeb ua ntej koj pib. Hnab looj tes, khaub ncaws ua haujlwm, thiab tsom iav tiv thaiv yog txhua tus pom zoo.
Kauj Ruam 2. Sau cov kab tawg me me nrog asphalt crack filler
Yog tias koj muaj ib qho tawg qis dua ¼ (6mm) dav, siv asphalt crack filler. Txheeb daim ntawv lo rau daim ntawv thov kev qhia lossis siv raws li hauv qab no:
- Co lub raj mis kom sib tov cov khoom sib npaug.
- Txiav tawm sab saum toj ntawm lub taub hau kom qhib tau nqaim dua qhov tawg. (Yog tias tsis muaj lub taub hau, thauj cov khoom rau hauv rab phom asphalt caulk xwb.)
- Nyem qhov muab tub lim ncaj qha rau hauv qhov tawg kom txog thaum nws yaug nrog txoj kev tsav tsheb.
- Cia kom qhuav rau 24 teev. Yog tias tus muab tub lim tau poob qis dua qib kev tsav tsheb, siv lub tsho ntxiv.
- Tos tsawg kawg 24 teev tom qab lub tsho kawg ua ntej taug kev lossis tsav tsheb hla kev kho.
Kauj Ruam 3. Yuav cov nab kuab asphalt thaj ua rau tawg ntau dua
Cov khoom siv no yog npaj rau "tus nab npawb nplai" lossis "kab laug sab kab laug sab" cov qauv tawg, ib qho tawg tawg ntau dua ¼ "(6mm), thiab kev nyuaj siab me me qis dua 2" (5cm).
Yog tias tus nab kuab tawg yog qhov hnyav, ib feem ntawm asphalt yuav raug cais tawm ntawm txoj kev tsav tsheb. Koj tuaj yeem ua tiav kev kho kom zoo dua yog tias koj tshem tag nrho cov no, tom qab ntawd rov ua lub qhov uas siv cov txheej txheem pothole saum toj no
Kauj Ruam 4. Tshaj cov tsiaj txhu thaj ua rau thaj nrog asphalt squeegee
Ncuav me ntsis ntawm cov khoom nkag mus rau qhov chaw puas. Tshaj tawm nrog asphalt squeegee (lossis txhuam asphalt) kom txog rau thaum kev puas tsuaj raug npog nrog ⅛ rau ¼ (3 txog 6 hli) ntawm cov khoom.
Txheeb daim ntawv qhia ua ntej. Qee yam khoom yuav tsum tau muab sib xyaw rau hauv lub thoob ua ntej thov
Kauj Ruam 5. Rov ua dua kom txog qib
Tshaj tawm ntawm cov tsiaj txhu ntxiv cov khoom kom txog thaum thaj tsam tawg lossis kev nyuaj siab yog qib nrog nws ib puag ncig.
Rau kev hloov pauv ntau dua, rub tawm ib txheej nyias ib lossis ob txhais taw (0.3 txog 0.6m) hauv txhua qhov kev taw qhia
Kauj Ruam 6. Cia kom qhuav
Cov khoom siv yuav hnyav dua li ob peb teev, nyob ntawm huab cua thiab qhov tob ntawm kev kho.
Kauj Ruam 7. Rov ua dua yog tias xav tau
Kev kho tuab yuav tawg me ntsis hauv ob peb hnub. Thov ib lub tsho me me ntxiv yog tias qhov no tshwm sim.
Kauj Ruam 8. Cia 24 teev rau lub blacktop kom qhuav thiab kho ua ntej nres tsheb lossis taug kev ntawm txoj kev tsav tsheb
Yees duab - Los ntawm kev siv qhov kev pabcuam no, qee cov ntaub ntawv yuav raug muab qhia rau YouTube
