Kusiyana pakati pa asphalt kulowetsedwa, tack wosanjikiza ndi kusindikiza wosanjikiza!
Zofunikira zomanga za asphalt zimayenda motere. Mafuta a kulowamo amagwiritsa ntchito asphalt pc-2, ndipo mlingo wake umatha kutsimikizika ndi kupopera kutsutsidwa molingana ndi muyezo wa 1.5 malita pa mitambo, ndipo kuwunika kwamiyala sikuyenera kukhala kochepera 5mm. Pambuyo kupopera mafuta olowa m'malo mwake, pomwe mapiri a emu-1 a phula amafunika kupatsa, kukula kwa malita a 2,5-1ct, ndipo makulidwe sayenera kukhala ochepera 0,6. Musanatasaume nephalrete, mafuta a tack ayenera kuthiridwa m'magawo apamwamba ndi otsika a chidindo chotsika, komanso m'mbali mwa ma curbs, zitsime zamvula ndi zina. Mafuta a Tack amagwiritsa ntchito emulsimed asphalt pc-3, ndipo mlingo wake ndi malita 0,5 pa mita imodzi.

M'dera lamvula ndi nyama yadziko, ngati phula la phula la phula la masitepe limakhala ndi chidwi chachikulu ndipo pamafunika kudutsa, kapena kuti magalimoto azitha kuthira malo owiritsa.
Ndikofunikira kusiyanitsa mosamalitsa pakati pa mkulu wotsika wotsika komanso mafuta osanjikiza: Cholinga cha chidindo chotsirizika chapansi ndikutchinga pansi, ndipo sizoyenera kuti zikhazikike; Mafuta ovomerezeka amafunikira kulowerera kuzama kwa ena. Palinso kusiyana kwakukulu pazogwira ntchito ndi zolinga zawo. Mu ntchito zina zamakono, popeza mafuta ophatikizika omwe amathiridwa ndi maziko a semi-rigid sangalowe, ophatikizidwa ndi mchenga amakonkhedwa ndi mafuta osanjikiza ngati chidindo chotsika. Izi zitha kusewera ndi ntchito yosindikiza, koma sangathe kusintha mafuta osanjikiza.
Chisindikizo chosalala nthawi zambiri chimagwiritsidwa ntchito pokonzanso misewu yayikulu ya kalasi yachiwiri komanso yotsika mtengo kwambiri, komanso yoyenera kutsimikizira kutsitsa kwamisewu yayikulu yomangidwa kumene.
Chophimba chotsikira chimakhala pamwamba pa maziko a semi-rigid. Ntchito zake ndi: Choyamba, kuteteza maziko kuti asawonongeke ndi magalimoto omanga, omwe amalimbitsa pakuchiritsa zida zokhazikika; Chachiwiri, kuteteza madzi amvula kuti asatenge gawo limodzi. Chachitatu, kulimbikitsa kuphatikiza pakati pa osanjikiza ndi maziko. Pali njira zambiri zopangira chitetezo chapansi. Kuchita kumawonetsa kuti phula limodzi la asphalt ndi njira imodzi yazachuma komanso yothandiza.
Ntchito ndi nyengo zogwiritsidwa ntchito za phula la phula la asphalt zimasanjikiza, tack wosanjikiza ndi kusindikiza osanjikiza ali motere:
(1) Ntchito ndi ntchito zogwirizira zolowa
Ntchito ya kusanjikiza kulowera ndikupangitsa kuti phula la phulusa lasungunuke komanso losasunthika losanjikiza bwino. Ndiwo woonda womwe umalowa pamwamba pa maziko osankha asphalt, phula la malasha kapena madzi phula pansi.
Zikakumana izi zikakumana, phula la phula liyenera kukonkhedwa:
① Masoka adayala ndi udzu wosweka miyala ya phula la phula la phula.
② simenti, laimu, ntchentche phulusa ndi omangirira ena okhazikika amakhazikika nthaka.
Phula la phula liyenera kuwazidwa pa malo osakhazikika a granular.
(2) Ntchito ndi zofunikira za Tack yosanjikiza
Ntchito ya Tack yosanjikiza ndikulimbitsa ubale wapakati pakati pa asphal asfa ndipo pakati pa phula ndi manrement manrete podi pompopompo.
Phula la Fact liyenera kuthiridwa m'milanduyi:
① Kusanjikiza kwa asphalt pansipa kapena atatu-osanjikiza masheya ozizira a phula atayipitsidwa kwakhala ndikuwonongeka kwapamwamba asanapatsidwe.
② Osanjikiza wosanjikiza wa phula amawonjezeredwa panja la phula la phula la phula la phula.
③ Kusanjikiza kwa phula la phula kumayikidwa panjira ya simenti.
Mbali za ma curbs, ma inlets amvula, zitsime zoyendera, etc. omwe akukhudzana ndi osakaniza a phula watsopano.
(3) Ntchito ndi zofunikira za chidindo
Ntchito ya Chisindikizo ndikusindikiza pansi mipata ndikuletsa chinyezi kuti chisalowe pamtunda kapena malo osanjikiza. Chotsekeka pamtunda wotsegulira chimatchedwa kuti chapamwamba chidindo chosindikizira, ndipo chimangacho chimayang'ana pansi pamtunda umatchedwa wotsika.
Chosanjidwa chapamwamba chiyenera kuyikika pazakudya za phulusa motsatira:
① Mipata yomwe ili mu phula la phula la phula ndi lalikulu komanso madzi ali ndi vuto.
② Phala lakale la phula lakale lili ndi ming'alu kapena kukonza.
③ Kumanja kwa phula lakale lomwe likufunika kupanikizidwa ndi kuvala chosanjikiza kukonza ma skid.
④ Kumanja kwatsopano kwa phula la phula labwino lomwe likufunika kupanikizidwa ndi kuvala chosanjikiza kapena choteteza.
(4) Udindo ndi zofunikira za chisindikizo
Udindo wa Chisindikizo Chosale: Ndi Chisindikizo cha Milpharal chidapangidwa mwamphamvu kufalitsa mapistel osakanizidwa ndi tchipisi kapena mafinya, timiyala.
Chophimba chotsikira chimayenera kukhazikitsidwa pansi pa phula la phula la phula pomwe chimodzi mwazinthu zotsatirazi zakwaniritsidwa:
Ipezeka kudera lamvula ndipo phula loyera la phula limakhala ndi mipata yayikulu komanso kutsika kwamadzi.
② Pambuyo pamunsi pamunsi yolumikizidwa, malo otsetsereka a phula satha kupakiridwa mu nthawi, ndipo magalimoto ayenera kutsegulidwa.
