Kudzivirira kuchengetedza kwepavement inzira inoshanda yekuchengetedza yakasimudzirwa zvakanyanya munyika yangu mumakore achangopfuura. Pfungwa yaro ndeyekutora matanho akakodzera panguva yakakodzera pachikamu chemugwagwa chakarurama apo mugwagwa wepamusoro hauna kukuvadzwa kwemaitiro uye kushanda kwebasa kwakaderera kune imwe nhanho. Matanho ekugadzirisa anotorwa kuti achengetedze kushanda kwepavement pamwero wakanaka, kuwedzera hupenyu hwebasa repavement, uye kuchengetedza mari yekugadzirisa nzira. Parizvino, matekinoroji ekuchengetedza ekudzivirira anowanzo shandiswa kumba nekune dzimwe nyika anosanganisira fog seal, slurry seal, micro-surfacing, panguva imwe chete gravel seal, fiber seal, yakaonda layer overlay, asphalt regeneration kurapwa uye mamwe matanho ekugadzirisa.

Fiber synchronized gravel seal ndiyo itsva yekudzivirira kuchengetedza tekinoroji yakaunzwa kubva kunze kwenyika. Iyi tekinoroji inoshandisa yakatsaurirwa fiber synchronized gravel seal chisimbiso kuparadzira michina panguva imwe chete kuparadzira (kusasa) asphalt binder uye girazi faibha, uye wozoiparadzira pamusoro Iyo aggregate inokungurutswa uye yobva yapfapfaidzwa neasphalt binder kuti iite nhurikidzwa nyowani. Fiber yakawiriraniswa kuvharwa kwematombo kunoshandiswa zvakanyanya mune dzimwe nzvimbo dzakagadziridzwa kunze kwenyika, uye ichiri nyowani yekuchengetedza tekinoroji munyika yangu. Iyo fiber yakawiriraniswa gravel yekuisa chisimbiso tekinoroji ine zvinotevera zvakanakira: inogona zvinobudirira kuvandudza yakazara ma mechanic zvimiro zvechisimbiso layer senge tensile, shear, compressive uye kukanganisa simba. Panguva imwecheteyo, inogona kuvhurika kune traffic nekukurumidza mushure mekuvakwa kwapera, ine yakanakisa skid kuramba, uye ine yakanaka yemvura inopikisa kuramba. , kunyanya yekudzivirira kunoshanda kwekudzivirira kwekutanga asphalt kongiri pavement, nekudaro ichiwedzera kutenderera kwekuchengetedza uye hupenyu hwebasa repavement.
Kuvaka: Kusati kwavakwa, muchina wekuongorora unoshandiswa kuongorora akaunganidzwa kaviri kubvisa pesvedzero yezvisina kurongeka. Iyo fiber synchronous gravel seal inogadzirwa uchishandisa yakakosha synchronous gravel seal paving michina.
Iyo chaiyo yekuvaka maitiro eiyo fiber synchronous gravel seal ndeye: mushure mekutanga dhizaini emulsified asphalt uye girazi fiber yakapfapfaidzwa panguva imwe chete, iyo aggregate inopararira. Iyo yakazara paving rate inofanira kusvika kune 120%. Huwandu hweasphalt hwakapararira kazhinji 0.15 yehuwandu hweasphalt yakachena. ~ 0.25kg/m2 kudzora; shandisa rubber tire roller inopfuura 16t kuikungurusa 2 kusvika ku3 nguva, uye kudzora kumhanya kwe 2.5 kusvika 3.5km/h; wobva washandisa aggregate recovery equipment kuchenesa yakasununguka aggregate; chengetedza kuti nzvimbo yemugwagwa haina kusununguka Kana zvimedu zvakasununguka, pfapfaidza chikamu chechipiri chemodified emulsified asphalt. Kuwanda kweasphalt kupararira kunowanzodzorwa pa 0.10 ~ 0.15kg/m2 yeasphalt yakachena. Mushure mekunge traffic yakavharwa kwe2 ~ 6 maawa, inogona kuvhurwa kune mota traffic.
