Mamiriro Ezvino Ekushandiswa Kwetsvagurudzo yeFly Ash muRoad Engineering

Kushandiswa kwedota rinobhururuka muhwaro hwenzira kunonyanya kutaurwa muzvikamu zviviri: dota rinobhururuka (raimu nedota rinobhururuka) zvinhu zvakagadzikana uye simende rinoputika nedota rinoputika. Zvinhu izvi zviviri zvakaunganidzwa muzviyero zvenyika, tekinoroji yacho yakakura, uye kune mashandisirwo akawanda anoshanda. Kushandiswa kwedota rinobhururuka pamusoro penzira kunonyanya kushandiswa pamusoro peasphalt musanganiswa wepamusoro uye simende yekongiri. Jiao Hua weChang'an University muongororo yake yemaster's thesis kunoratidza kuti kana dota rinobhururuka richitsiva upfu hwese hweore mumusanganiswa weasphalt weAC-16, harina kusimba kwekupisa kwakanyanya uye kugadzikana kwakanyanya kwekupisa kupfuura kwakasanganiswa nedota rinoputika. , kugadzikana kwemvura kwakagadziridzwa asi mhedzisiro yacho haisi yakanaka. Xie Jun, Wu Shaopeng, nevamwe vakadzidza mhedzisiro yekurapa pamusoro pemvura inofamba nedota rinoputika uye chinhu chinobatanidza pakukuvara kwehunyoro hwemusanganiswa weasphalt. Kubatanidza filler nechinhu chinobatanidza nedota rinoputika kunonzi composite fly ash modifier. Hunhu hwecomposite fly ash modifier hwakanyanya kuratidzwa ne scanning electron microscopy uye Fourier transform infrared spectroscopy. Sechinozadza, mhedzisiro yaro pakunzwa kwehunyoro hwemusanganiswa weasphalt yakaongororwa kuburikidza nekuyedzwa kwehunyoro hwemusanganiswa weasphalt zvisina tsarukano, kuyedzwa kwehunyoro hwemusanganiswa westatic, uye kuyedzwa kwekuneta zvisina tsarukano. Mhedzisiro yacho inoratidza kuti musanganiswa weasphalt une modifier yecomposite fly ash ine simba rakawanda rekunzwa uye simba rekunzwa panguva yechando uye ine hunyoro hwakanaka. Pamusoro pezvo, musanganiswa weasphalt wakagadziriswa une modifier yehunyoro iri nani, unodzivirira kuchinjika zvachose, uye hupenyu hwekuneta mushure mekurapwa kwehunyoro hwakati. Mhedziso: Musanganiswa weasphalt une modifier inogona kuvandudza hunyoro hwemusanganiswa weasphalt.

Makomba emvura anobhururuka anoshandiswawo zvakanyanya mukugadzira migwagwa, kunyanya muzvikamu zvemigwagwa yevhu rakapfava. Inogona kushandisa zvizere huremu hushoma hwemakomba emvura kuderedza huremu hwemakomba emvura pamwe nekumanikidzwa kwenheyo yakapfava yevhu, nokudaro ichideredza kugara kwese uye kuvandudza kugadzikana kwemakona. Saizvozvowo, kuzadza makomba emvura nevhu rakapfava pamusoro pebhiriji kunogona kugadzirisa dambudziko rekusvetuka kwebhiriji rinokonzerwa nekugadzika kunokonzerwa nehuremu hwevhu rakapfava pamusoro pebhiriji. Liu Tiejun akadzidza maitiro emuchina wemakomba emvura anoshandiswa sekuzadza makomba uye akasvika pamhedziso inotevera: kuwanda kwemvura kwakaoma kwemakomba emvura kwakaratidza kutanga kwawedzera uye kwozodzikira nekuwedzera kwehuwandu hwehunyoro, uye kuwanda kwakanyanya kwehunyoro hwakaoma kwaive 19%; Kuwanda kwemvura mumarasha emarasha kunoderera zvakanyanya nekuwedzera kwehuwandu hwakaoma. Kana kuwanda kwemvura mumarasha ari pasi pe1.35g/cm3, kuwanda kwemvura kwakaoma hakuna zvakunokanganisa pahuwandu hwayo hwemvura; kubatana kwedota remafuru kunowedzera nehuwandu hwemvura Kana hunyoro hwedota remafuru huchiwedzera uye huchidzikira, uye kudzikira kunonoka kana hunyoro huri pasi pe26%, zvikasadaro hunodzikira nekukurumidza; kana hunyoro hwedota remafuru huchiwedzera ne1%, kona yekukweshana yemukati inodzikira neinenge 0.25°; Kubatana kwedota remafuru kunowedzera zvakananga nekuwedzera kwedhigirii rekukweshana, nepo kona yekukweshana yemukati yedota remafuru inowedzera zvakanyanya nekuwedzera kwedhigirii rekukweshana; hunyoro hwedota remafuru Kana iri pedyo nehuwandu hwehunyoro hwakanaka kana kuti iri pedyo ne100% yekukweshana, kudzikira kwekubatana uye kona yekukweshana yemukati nekuwedzera kwenguva dzekukweshana, uye zviri nyore kusvika padanho rekutanga rekukweshana. Chen Yunyong naGao Liang vakaitawo bvunzo dzemukati meimba pamadziro edota remafuru akasimbiswa. Zvichienderana nepfungwa yekufanana, varume vaviri ava vakaderedza madziro chaiwo pachiyero che1:8 uye vakashandisa bidirectional geogrid sezvinhu zvekusimbisa, uye vakaita tsvakiridzo yekuyedza pamusoro pekumanikidzwa uye kumanikidzwa kwemadziro akasimbiswa edota remafuru. Zvakabuda zvinoratidza kuti kusawirirana kwenzvimbo yemvura inoputika neash kunogona kuderedzwa zvakanyanya nekushandiswa kwegeogrid, uye kugona kwekutakura zvinhu kunogona kuvandudzwa zvakanyanya.
