Synchronous gravel sealing tekinoroji yakashandiswa zvishoma nezvishoma kumba nekune dzimwe nyika. Iyo inyanzvi yehupfumi uye inoshanda yekuchengetedza tekinoroji. Rori yekuisa chisimbiso yematombo inoshandiswa kuparadzira asphalt binder (yakagadziridzwa asphalt, emulsified asphalt, nezvimwewo) uye matombo emhando imwe chete (anowanzo shandiswa 4 kusvika 6 mm, 6 kusvika 10 mm) mumugwagwa panguva imwe chete, uye ozopfuura nepakati. muchina wekutenderedza matayi erabha Kana kuti kutenderedzwa kwemotokari kunoumba jira rakapfeka reasphalt gravel pavement. Inogona kugadzirisa mitswe yemigwagwa, kuderedza kutsemuka kwepavevement, uye kuwedzera kupfeka. Iyo asphalt firimu yakaumbwa pamugwagwa wemugwagwa inogona kupikisa kupinza kwemvura yepamusoro. Iine nguva pfupi yekuvaka, tekinoroji yakapusa, uye kushanda kwakasimba. Parizvino, iyo synchronous gravel seal layer inoshandiswa mukuchengetedza kuchengetedza kwemigwagwa mikuru, migwagwa mikuru, migwagwa yedhorobha neyemataundi, uye inogona zvakare kushandiswa mugadziko yakapfeka layer yemigwagwa mitsva uye yepasi chisimbiso chisimbiso chenzvimbo dzakasimbiswa dzemigwagwa. Kana mari yekuvaka yakamanikana, inogona kushandiswa senzira inochinjika yemigwagwa mikuru yakaderera.
Munguva yekuvaka chaiyo, tekinoroji iyi inonyanya kutarisisa pamusoro pedenga, nepo chepamusoro chisimbiso chisimbiso uye yekupfeka layer inowanzo furatirwa, zvichikonzera kurasikirwa kwezviwanikwa. Mumakore achangopfuura, matekinoroji akadai senge micro-surfacing uye ultrasonic abrasion yakaramba ichibuda. Mukugadzirisa kuchengetedza kwekudzivirira kwemigwagwa yeasphalt, teknolojia yekuisa chisimbiso inowanzoshandiswa. Tekinoroji dzinowanzo shandiswa dzinosanganisira kupisa uye kutonhora kutetepa layer yekuvharisa uye crack sealing. layers nemamwe marudzi mazhinji. Sarudzo huru yekuisa chisimbiso tekinoroji yeasphalt pavement ndiyo imwe chete asphalt gravel sealing layer. Iyi tekinoroji inogona kunyatso kuchengetedza mutengo weprojekiti. Mukuwedzera, sezvo teknolojia iyi yakashandiswa muFrance pakupera kwezana remakore rechi20, yakakurumidza kuwedzera kuUnited States neEurope. Nyika, kusanganisira shoma dziri muAsia, Africa, neAustralia, dzakatangawo kushandisa tekinoroji iyi muzvirongwa zvakati. Nhamba dzinoratidza kuti chete 5% yemapurojekiti muEurope haashandise tekinoroji iyi kudzivirira kugadzirisa migwagwa. Parizvino, kana uchishandisa iyi tekinoroji yekuisa chisimbiso munyika yedu, zvinotevera zvinodiwa zvinofanirwa kuzadzikiswa.
(1) Ongorora zvinodiwa. Kuti udzivise kusakara uye kubvaruka kwemotokari panguva yekushanda kwemugwagwa mukuru, mapavement aggregates anofanirwa kuve nekuoma kwakakwana. Kunyanya munyaya yekuyerera kwemotokari uye mutoro wemotokari, kusarudzwa kwekuoma kwehuwandu kunowedzera kuoneka; iyo gradation kazhinji haina kusanganiswa nehupfu. Shandisa rudzi rumwe rwegiredhi; paunenge uchisarudza maaggregates, kuitira kudzivirira kutaridzika kwepini-flake marudzi, shandisa cubic chimiro kuti uve nechokwadi chekumisikidza kwakazara kweaggregates muasphalt.
(2) Asphalt. Kusarudzwa kweasphalt kunofanirwa kutanga kuzadzisa zvinodiwa pakusarudzwa kweasphalt zvakaiswa nedhipatimendi remigwagwa. Pahwaro hwekusangana zvakatemwa, emulsified, modified, rubber, kana yakajairika petroleum asphalt inogona kusarudzwa.
(3) Kushandiswa kwezvinhu. Paunenge uchishandisa tekinoroji yekuisa chisimbiso chematombo ekugadzirisa migwagwa, matombo anofanirwa kubatanidzwa zvakasimba, uye dombo rinofanira kuvharwa zvizere neasphalt kuti rirambe kupfeka uye kubvaruka munzira yemugwagwa nemavhiri. Kana imwe nguva iyo inopararira yakawanda yakawandisa, asphalt binder ichasvinwa kubva pamatombo mumatombo apo motokari inoputika mumugwagwa, uye nzvimbo yemafuta ichaonekwa, nokudaro kuderedza indekisi ye-anti-skid uye friction yemugwagwa; zvisinei, Kana uwandu hwematombo hwakapararira hwakanyanya kuduku, matombo haagoni kusungirirwa zvinobudirira, uye matombo anogona kukandwa kunze kwemugwagwa.
Muchidimbu, kushandiswa kweasphalt panguva imwe chete yematombo ekuisa chisimbiso tekinoroji kune yakakosha inoshanda mhedzisiro. Izvo hazvigone chete zvinobudirira kudzivirira kuunganidzwa kwemvura mumugwagwa, kuvandudza simba rekugera remugwagwa, asi zvakare zvinobudirira kusimudzira kushanda kwemugwagwa pasi peyakadzika uye yakakwirira tembiricha mamiriro. Iyo yakakwira crack resistance inogona kuchengetedza asphalt pamusoro kubva mukukukurwa kana kuputika. Iyi tekinoroji inoparadzira asphalt yakagadziridzwa uye ibwe rinoenderana zvakaenzana munzira yemugwagwa panguva imwe chete kuti ive nechokwadi chekubatana kunoshanda pakati pezviviri uye kuwedzera kunamira uye simba pakati pezviviri. Pamusoro pezvo, tekinoroji iyi iri nyore, inochengetedza zviwanikwa uye mutengo, uye ine simba rinogoneka. Panguva imwecheteyo, nekuda kwezvinodiwa zvakakwirira zvemidziyo yakabatana, mari yebasa inoderedzwa zvakanyanya. Naizvozvo, iyi tekinoroji nzira inogona kusimudzirwa kuvandudza kutsemuka kuramba uye anti-skid kuita kwemigwagwa yeasphalt zvakanyanya sezvinobvira.
